Journal Articles: Pediatrics

Retinol (vitamin A) is essential, so the objective of this Institutional Review Board approved study is to evaluate retinol placental concentration, intrauterine transfer, and neonatal status at time of term delivery between cases of maternal retinol adequacy, insufficiency, and deficiency in a United States population. Birth information and biological samples were collected for mother-infant dyads (n = 260). Maternal and umbilical cord blood retinol concentrations (n = 260) were analyzed by HPLC and categorized: deficient (≤0.7 umol/L), insufficient (>0.7-1.05 umol/L), adequate (>1.05 umol/L). Intrauterine transfer rate was calculated: (umbilical cord blood retinol concentration/maternal retinol concentration) × …

Cardiorespiratory Fitness Diminishes The Effects Of Age On White Matter Hyperintensity Volume, Nathan F. Johnson, Ahmed A. Bahrani, David K. Powell, Gregory A. Jicha, Brian T. Gold

Physical Therapy Faculty Publications

White matter hyperintensities (WMHs) are among the most commonly observed marker of cerebrovascular disease. Age is a key risk factor for WMH development. Cardiorespiratory fitness (CRF) is associated with increased vessel compliance, but it remains unknown if high CRF affects WMH volume. This study explored the effects of CRF on WMH volume in community-dwelling older adults. We further tested the possibility of an interaction between CRF and age on WMH volume. Participants were 76 adults between the ages of 59 and 77 (mean age = 65.36 years, SD = 3.92) who underwent a maximal graded exercise test and structural brain …

OBJECTIVE: Hypotension following endotracheal intubation in the ICU is associated with poor outcomes. There is no formal prediction tool to help estimate the onset of this hemodynamic compromise. Our objective was to derive and validate a prediction model for immediate hypotension following endotracheal intubation.

METHODS: A multicenter, prospective, cohort study enrolling 934 adults who underwent endotracheal intubation across 16 medical/surgical ICUs in the United States from July 2015-January 2017 was conducted to derive and validate a prediction model for immediate hypotension following endotracheal intubation. We defined hypotension as: 1) mean arterial pressure < 65 mmHg; 2) systolic blood pressure < 80 mmHg and/or decrease in systolic blood pressure of 40% from baseline; 3) or the initiation or increase in any vasopressor in the 30 minutes following endotracheal intubation.

RESULTS: Post-intubation hypotension developed in 344 (36.8%) patients. …

Comparison Of Longitudinal Changes In Resting State Functional Magnetic Resonance Imaging Between Alzheimer’S And Healthy Controls, Berk Can Yilmaz

Theses

Resting State Functional Magnetic Resonance Imaging (rs-fMRI) is a technique that is widely used for analyzing brain function using different approaches and methods. This study involves rs-fMRI analysis of Blood Oxygenation Level Dependent (BOLD) signals acquired from Alzheimer’s disease (AD) Patients and Healthy Controls (HC). Each subject in the study had both functional and anatomical images with at least one rs-fMRI scan with their Anatomical (T1) scans. Previous rs-fMRI studies have demonstrated that AD shows differences in Amplitude of Low Frequency (<0.1 Hz) Fluctuations (ALFF), and Regional Homogeneity (ReHo) measures according to HCs.

The aim of the study is to investigate individual and group level differences using ReHo and mALFF related …

Pericardiocentesis Indications And Complications: A Retrospective Observational Study In A Tertiary Care Hospital In Karachi, Pakistan, Abdul Baqi, Intisar Ahmed Aug 2020

Pericardiocentesis Indications And Complications: A Retrospective Observational Study In A Tertiary Care Hospital In Karachi, Pakistan, Abdul Baqi, Intisar Ahmed

Section of Cardiology

Introduction: Pericardiocentesis is crucial for the diagnosis and management of diseases responsible for significant pericardial effusions. Pericardiocentesis was performed the first time by Riolanus for cardiac tamponade. He described the process of trephination of the sternum to remove the abnormally accumulated fluid from the pericardial space. However, with the advancement of expertise in echocardiography assisted procedures, echocardiography-guided diagnostic and therapeutic pericardiocentesis is now considered standard clinical practice in the treatment of pericardial effusions.
Objectives: We aim to study different causes of pericardial effusion and indications of pericardiocentesis as well as complications associated with it in our population.
Methods: This is …


The Intertwined Relationship Between Malnutrition And Poverty, Faareha Siddiqui, Rehana Salam, Zohra S. Lassi, Jai K. Das Aug 2020

The Intertwined Relationship Between Malnutrition And Poverty, Faareha Siddiqui, Rehana Salam, Zohra S. Lassi, Jai K. Das

Woman and Child Health

Despite social and economic development, the burden of malnutrition across the globe remains unacceptably high. A vital relationship exists between nutritional status, human capital, and economic standing. Malnutrition adversely affects the physiological and mental capacity of individuals; which in turn hampers productivity levels, making them and their respective countries more susceptible to poverty. A two-way link exists between malnutrition and poverty, creating a vicious cycle with each fueling the other. Malnutrition produces conditions of poverty by reducing the economic potential of the population and likewise, poverty reinforces malnutrition by increasing the risk of food insecurity. The aim of the paper …

The Slc25a42 Transcript Is A Biomarker For Fetal Reprogramming In Response To Placental Insufficiency In Preterm Newborns Under 32 Weeks Gestation-A Pilot Study., Fu-Sheng Chou, Pei-Shan Wang

Manuscripts, Articles, Book Chapters and Other Papers

Introduction: Timing of medical delivery of preterm newborns exposed to placental insufficiency is largely determined by umbilical artery blood flow and maternal clinical manifestations. There is a lack of tools to properly assess fetal body response to placental insufficiency before or upon delivery. Yet, short- and long-term comorbidities associated with placental insufficiency and the consequential intrauterine growth restriction may be a result of fetal response following prolonged stress. This study aims to establish a procedure to investigate fetal/neonatal transcriptional response to placental insufficiency as part of an initiative to identify cost-effective biomarkers for assessing fetal response to placental insufficiency.

Toxicology and Cancer Biology Faculty Publications

The insulin-like growth factor 1 receptor (IGF-1R) governs several signaling pathways for cell proliferation, survival, and anti-apoptosis. Thus, targeting IGF-1R appears as a reasonable rationale for tumor treatment. However, clinical studies showed that inhibition of IGF-1R has very limited efficacy due to the development of resistance to IGF-1R blockade in tumor cells. Here, we discovered that prolonged treatment of colon cancer cells with IGF-1R inhibitors (BMS-754807 and GSK1838705A) stimulates p70 KDa ribosomal protein S6 kinase 1 (p70S6K1) activation, a well-known kinase signaling for cell survival. We also found that p70S6K1 activation by IGF-1R inhibition is independent of K-Ras and PIK3CA …

Folic Acid Supplementation In Patients With Elevated Homocysteine Levels, Alan D. Kaye, George M. Jeha, Alex D. Pham, Mitchell C. Fuller, Zachary I. Lerner, Gerald T. Sibley, Elyse M. Cornett, Ivan Urits, Omar Viswanath, Christopher G. Kevil

School of Medicine Faculty Publications

Introduction: Folic acid is the most important dietary determinant of homocysteine (Hcy). Hcy serves as a critical intermediate in methylation reactions. It is created from methionine and either converted back to methionine or transformed into cysteine. This process is aided through several enzymes and three vitamins, folic acid, B12, and B6. Daily supplementation with 0.5–5.0 mg of folic acid typically lowers plasma Hcy levels by approximately 25%. Hyperhomocysteinemia is a known risk factor for coronary artery disease. In this regard, elevated levels of Hcy have been found in a majority of patients with vascular disease. Methods: A literature review of …

Not All Free Air In The Nicu Is Necrotizing Enterocolitis., Paul Holtrop, Paras Khandar, Nathan Novotny

Articles

When a tiny preterm baby in our neonatal intensive care unit (NICU) has an intestinal perforation, it is always necrotizing enterocolitis (NEC), right? Not so fast, my friend. Many of these preterm infants who perforate have free air from spontaneous intestinal perforation (SIP) and not NEC. As it turns out, not all free air in the NICU is NEC. How can you tell the difference and does it matter?

It can be challenging to tell the difference, but SIP tends to occur earlier in life, often within the first week, whereas NEC usually occurs slightly later. One analysis of a …


The Impact Of Myeloid-Mediated Co-Stimulation And Immunosuppression On The Anti-Tumor Efficacy Of Adoptive T Cell Therapy, Pasquale Patrick Innamarato Aug 2020

The Impact Of Myeloid-Mediated Co-Stimulation And Immunosuppression On The Anti-Tumor Efficacy Of Adoptive T Cell Therapy, Pasquale Patrick Innamarato

USF Tampa Graduate Theses and Dissertations

Adoptive T cell therapy (ACT) in combination with lymphodepleting chemotherapy is an effective strategy to induce the eradication of tumors, providing long-term regression in cancer patients. However, only a minority of patients that receive ACT with tumor infiltrating lymphocytes (TILs) exhibit durable benefit. Thus, there is an urgent need to define strategies that potentiate anti-tumor activity conducted by adoptively transferred T cells. In these studies, we aimed to identify novel strategies to enhance the therapeutic efficacy of ACT. Accordingly, we describe the disparate roles of myeloid cells in the context of ACT characterized by the augmentation of TIL proliferation in …

Factor Structure And Measurement Invariance Of The Maslach Burnout Inventory In Emergency Medicine Residents, Tim P. Moran, Nicole Battaglioli, Simiao Li-Sauerwine

Journal of Wellness

Introduction: Emergency medicine residents suffer from high rates of occupational burnout. Recent research has focused on identifying risk and protective factors for burnout as well as targets for intervention. This research has primarily employed the Maslach Burnout Inventory to evaluate burnout in this population. Factor analytic work has identified three underlying factors measured by the Maslach Burnout Inventory: Emotional Exhaustion, Depersonalization, and Personal Accomplishment. However, this three-factor structure has not been evaluated in emergency medicine residents. Furthermore, its structural equivalence has not been demonstrated across commonly-studied risk factors, such as gender and year of post-graduate training. In the present study, …


Friendship And Informant Characteristics Associated With The Agreement Among Adolescent And Friend Ratings Of Behavior Problems, Brea-Anne Lauer, Kimberly Renk Aug 2020

Friendship And Informant Characteristics Associated With The Agreement Among Adolescent And Friend Ratings Of Behavior Problems, Brea-Anne Lauer, Kimberly Renk

Journal of Adolescent and Family Health

The present study investigated the relative agreement between adolescent self-reports and friend informant reports of behavior problems as well as factors that might impact this agreement. High school students were placed into friendship dyads based on perceived friendship closeness and rated friendship quality, their own internalizing and externalizing behavior problems, and the behavior problems of their matched friend. Self- and friend ratings demonstrated high levels of agreement across behavior problems presentations. Further, raters’ own behavior problems were related inconsistently to rating agreement, whereas friendship quality demonstrated some impact on the informant’s reports of specific behavior problems. This study provided additional …
