The Role Of Inflammatory Pathways In Development, Growth, And Metabolism Of Skeletal Muscle In Iugr Offspring: Blood Gene Expression Of Inflammatory Factors As Novel Biomarkers For Assessing Stress And Wellbeing In Exotic Species, Robert J. Posont

Department of Animal Science: Dissertations, Theses, and Student Research

Our first study identified the effects of maternal inflammation-induced intrauterine growth restriction (MI-IUGR) on growth and muscle glucose metabolism in offspring supplemented with curcumin. MI-IUGR lambs exhibited asymmetric growth restriction at birth and 30d of age, but normal glucose-stimulated insulin secretion. Hindlimb glucose oxidation was reduced by MI-IUGR and not improved by curcumin supplementation. Ex vivo muscle glucose oxidation was reduced by MI-IUGR but improved somewhat by curcumin. These finding indicate that fetal programming responses to MI contribute to neonatal growth and metabolic deficits. Neonatal curcumin supplementation had minimal effect on growth deficits but may improve glucose metabolism. …

Asthma-Related Health Outcomes In New Jersey After A Natural Disaster Event, My Ngoc Thuy Nguyen

Health Services Research Dissertations

The occurrence of a natural disaster event such as a hurricane may further hinder the asthma management of asthmatic individuals. Unmanaged asthma has led to increased work absenteeism, preventable emergency department visits, costly hospitalizations and possibly death in severe cases. To improve asthma management in asthmatic adults in New Jersey (NJ) following a natural disaster event, this study examined whether predisposing, enabling and need factors are predictors for asthma exacerbation and asthma-related health care utilization in New Jersey. A retrospective secondary analysis of New Jersey Behavioral Risk Factor Surveillance System (NJBRFSS) data and New Jersey Asthma Call Back Survey (NJACBS) …

Effectiveness Of Artificial Neochordae Implantation In Tricuspid Valve Repair, Salih Salihi, H Tarik Kiziltan, Ahmad Huraibat, Askin Ali Korkmaz, Ibrahim Kara, Mustafa Guden

The Texas Heart Institute Journal

Various techniques for treating tricuspid regurgitation have been described; however, because of scarce data about the long-term outcomes of different repairs, the optimal technique has not been established. We evaluated the effectiveness and durability of artificial neochordae implantation in the treatment of tricuspid regurgitation. From 2009 through 2014, 507 patients underwent tricuspid valve repair at our institution. Of those, 48 patients implanted with artificial neochordae were included in our study. The median age of the participants was 62 years (range, 4-77 yr) and 50% were women. Thirty patients (63%) were in New York Heart Association functional class III, and 11 …

Minimally Invasive Endovascular Repair Of Ascending Thoracic Aortic Aneurysm With Use Of Local Anesthesia And Conscious Sedation, Abdelkader Almanfi, Zvonimir Krajcer

The Texas Heart Institute Journal

Ascending thoracic aortic aneurysm (ATAA) is typically treated surgically. No commercially available device has been specifically designed for endovascular ATAA repair, and currently, multiple anatomic and technical challenges affect its feasibility. Previously, such repairs have been performed with the patients under general anesthesia. We describe a novel, minimally invasive approach to endovascular repair of ATAA, involving local anesthesia, conscious sedation, and 24-hour hospitalization. Two consecutive male patients (ages, 79 and 54 yr) who had comorbidities underwent percutaneous transfemoral endovascular ATAA repair with use of commercially available endografts. Patient 1 had a saccular aneurysm, and Patient 2 had a pseudoaneurysm consequent …

Unconventional 2:1 Ventricular Pacing In A Neonate With Congenital Heart Block And Biventricular Noncompaction, Andrew E Schneider, Philip L Wackel

The Texas Heart Institute Journal

Congenital complete heart block with concomitant biventricular noncompaction cardiomyopathy has been reported once previously. Although not universal, when restrictive physiology is present, impaired diastolic filling may pose a distinct challenge to pacing during the neonatal period. We present the case of a neonate with congenital complete heart block and biventricular noncompaction that resulted in severe diastolic dysfunction and atrioventricular dyssynchrony. We intentionally used 2:1 ventricular pacing to provide atrioventricular synchrony with every paced beat, and this resulted in hemodynamic and clinical improvement. This unconventional pacing technique may be beneficial in other neonates who have complete heart block and diastolic dysfunction.

Effect Of Percutaneous Suction Thromboembolectomy On Improved Right Ventricular Function, Akbarshakh Akhmerov, Heidi Reich, James Mirocha, Danny Ramzy

The Texas Heart Institute Journal

Venous thromboembolism is a leading cause of cardiovascular death. Historically, surgical intervention has been associated with high morbidity rates. Pharmacologic therapy alone can be inadequate for patients with substantial hemodynamic compromise, so minimally invasive procedures are being developed to reduce clot burden. We describe our initial experience with using the AngioVac system to remove thromboemboli percutaneously. We reviewed all suction thromboembolectomy procedures performed at our institution from March 2013 through August 2015. The main indications for the procedure were failed catheter-directed therapy, contraindication to thrombolysis, bleeding-related complications, and clot-in-transit phenomena. We collected details on patient characteristics, procedural indications, thrombus location, …

Faculty Publications & Research of the TUC College of Pharmacy

Background: Data suggest that vancomycin + β-lactam combinations improve clearance of methicillin-resistant Staphylococcus aureus(MRSA) bloodstream infections (BSIs). However, it is unclear which specific β-lactams confer benefit. This analysis evaluates the impact of concomitant empiric cefepime on outcomes of MRSA BSIs treated with vancomycin.

Methods: Retrospective cohort study of adults with MRSA BSI from 2006 to 2017. Vancomycin + cefepime therapy was defined as ≥24 hours of cefepime during the first 72 hours of vancomycin. The primary outcome was microbiologic failure, defined as BSI duration ≥7 days and/or 60-day recurrence. Multivariable logistic regression was used to evaluate the association between …

Ecological Determinants Of Respiratory Health: Examining Associations Between Asthma Emergency Department Visits, Diesel Particulate Matter, And Public Parks And Open Space In Los Angeles, California, Jason A. Douglas, Reginald S. Archer, Serena E. Alexander

Health Sciences and Kinesiology Faculty Articles

Los Angeles County (LAC) low-income communities of color experience uneven asthma rates, evidenced by asthma emergency department visits (AEDV). This has partly been attributed to inequitable exposure to diesel particulate matter (DPM). Promisingly, public parks and open space (PPOS) contribute to DPM mitigation. However, low-income communities of color with limited access to PPOS may be deprived of associated public health benefits. Therefore, this novel study investigates the AEDV, DPM, PPOS nexus to address this public health dilemma and inform public policy in at-risk communities. Optimized Hotspot Analysis was used to examine geographic clustering of AEDVs, DPM, and PPOS at the …

Ethanolamine Regulates Cqsr Quorum-Sensing Signaling In Vibrio Cholerae, Samit Watve, Kelsey Barrasso, Sarah A. Jung, Kristen J. Davis, Lisa A. Hawver, Atul Khataokar, Ryan G. Palaganas, Matthew B. Neiditch, Lark Perez, Wai-Leung Ng

College of Science & Mathematics Departmental Research

The pathogen that causes cholera, Vibrio cholerae, uses the cell-cell communication process known as quorum sensing (QS) to regulate virulence factor production and biofilm formation in response to changes in population density and complexity. QS is mediated through the detection of extracellular chemical signals called autoinducers. Four histidine kinases, LuxPQ, CqsS, CqsR and VpsS, have been identified as receptors to activate the key QS regulator LuxO at low cell density. At high cell density, detection of autoinducers by these receptors leads to deactivation of LuxO, resulting in population-wide gene expression changes. While the cognate autoinducers that regulate the activity of …

The Influence Of Stressful Life Events On The Development Of Type 2 Diabetes, Joshua Minks

Dissertations

This study examined the relationship between distress and the development of Type 2 diabetes mellitus (T2DM) in the presence of established risk factors. Distress secondary to mental health disparities, stressful life events, and work conditions has been shown to promote insulin resistance and the development of T2DM.

Subjects (N=79) diagnosed with T2DM within the previous six months were recruited from SSM Health Centers and VA Medical Centers in the greater St. Louis area. They completed the Recent Life Changes Questionnaire, ENRICHD Social Support Instrument, and a demographic survey and analyses were conducted to determine differences between the veteran …

The Effect Of Sepsis On Cerebral Microvascular Blood Flow, Laura Mawdsley, Mamadou Diop, Chris G. Ellis

Western Research Forum

Background: Sepsis is a dysregulated host response to infection that affects 18 000 000 people worldwide, and over 325 000 000 dollars are spent treating sepsis in Canada every year. One of the symptoms of severe sepsis is an altered mental state, which is accompanied with a measured decrease in oxygen levels in the skeletal muscle microvasculature. It is hypothesized that his altered mental state is due to a lack of oxygenated blood reaching the brain.

Hypothesis: After the onset of sepsis, microvascular cerebral blood flow and oxygen levels in the blood will decrease. Onset of decreased blood flow in …

Dirt, Saliva And Leprosy: Anti-Inflammatory And Anti-Infectious Effects, Helieh S. Oz

Internal Medicine Faculty Publications

Ancient Egyptians smeared a mixture of dark soil on their eyelids and believed it protected eyes from unknown forces (illness). Recent studies have proven that the dark soil across the Nile River is rich in natural compounds including lead sulfide, which in low levels, promotes the production of nitric oxide (240-fold) by keratinocytes, with strong immune stimulatory and antimicrobial properties. Current investigations reveal anti-inflammatory and anti-infectious activities—including cytokines and chemokines—in saliva, as well as its friendly microbiota, which lines the surface of the oral cavity, its protection against inflammatory and infectious organisms in the stoma and other organs, such as …

Factors Associated With Condom Use With Non-Commercial Partners Among Sexually-Active Transgender Women In Cambodia: Findings From A National Survey Using Respondent-Driven Sampling., Siyan Yi, Amelia Plant, Sovannary Tuot, Phalkun Mun, Srean Chhim, Navy Chann, Pheak Chhoun, Carinne M. Brody

BACKGROUND: Globally, the prevalence of HIV among transgender women is much higher than that of the general adult population. This can be explained by the persistently low rate of consistent condom use among this population. This study was therefore conducted to explore factors associated with consistent condom use among sexually-active transgender women in Cambodia, specifically with their non-commercial partners.

METHODS: Data used for this study were collected as part of the National Integrated Biological and Behavioral Survey 2016. Participants were recruited from the capital city of Phnom Penh and 12 other provinces with high burden of HIV using the Respondent-Driven …

All Peer-Reviewed Publications

Objective: In Sub-Saharan Africa, there is an increase in trypanosome non-susceptibility to multiple trypanocides, but limited information on judicious trypanocide use is accessible to smallholder farmers and agricultural stakeholders in disease endemic regions, resulting in widespread multi-drug resistance. Huge economic expenses and the laborious nature of extensive field studies have hindered collection of the requisite large-scale prospective datasets required to inform disease management. We examined the efficacy of community-led data collection strategies using smartphones by smallholder farmers to acquire robust datasets from the trypanosomiasis endemic Shimba hills region in Kenya. We used Open Data Kit, an open-source smartphone application development …

The Role Of Thyroglobulin In Thyroid Hormonogenesis, Cintia E. Citterio, Héctor M. Targovnik, Peter Arvan

Pharmacy Faculty Articles and Research

In humans, the thyroid hormones T₃ and T₄ are synthesized in the thyroid gland in a process that crucially involves the iodoglycoprotein thyroglobulin. The overall structure of thyroglobulin is conserved in all vertebrates. Upon thyroglobulin delivery from thyrocytes to the follicular lumen of the thyroid gland via the secretory pathway, multiple tyrosine residues can become iodinated to form mono-iodotyrosine (MIT) and/or di-iodotyrosine (DIT); however, selective tyrosine residues lead to preferential formation of T₄ and T₃ at distinct sites. T₄ formation involves oxidative coupling between two DIT side chains, and de novo T₃ formation involves …

"Herpes zoster, also known as shingles, is a painful cutaneous eruption that develops following the reactivation of the varicella zoster virus (VZV), the same virus that causes chickenpox.¹ About 1 in 3 people in the United States will develop shingles, with an estimated 1 million cases occurring annually. Anyone with a history of chickenpox is at risk for shingles, but the risk increases with age and in patients who are immunocompromised.²"

Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente

Graduate Student Research Symposium

Usually not diagnosed until open laparotomy, aortoduodenalfistulas (ADF) are one of the rarest complications of intestinal transplant surgery. With an incidence rate of only 0.04% at autopsy and only 250 documented cases since the early 1800’s, aortoduodenal fistulas are the most deadly complications of intestinal transplantation with a mortality rate of 100% without surgical intervention. A 39 year old, two-time multi-visceral transplant African American female patient suffered from a primary aortoduodenal fistula formation in a primary modified multi-visceral transplant aortic stump graft site. With emergency open laparotomy repair, revascularization of the secondary multi-visceral transplant was performed, saving the life of …

Vapor Delivery Of Plant Essential Oils Alters Pyrethroid Efficacy And Detoxification Enzyme Activity In Mosquitoes, Scott T. O'Neal, Ellis J. Johnson, Leslie Catherine Rault, Troy D. Anderson

Department of Entomology: Faculty Publications

The use of synthetic insecticides to limit the spread of mosquito-borne disease faces a number of significant challenges, including insecticide resistance, concerns related to the environmental impact of widespread insecticide use, as well as slowed development of new insecticide chemistries. One important alternative to broadcast insecticides is the use of personal protection strategies to limit contact with vector species, including the use of spatial repellents that can employ synthetic pyrethroids or botanical products to effect control. A currently underexplored area of research involves the investigation of botanical products for their potential to serve as insecticide synergists when delivered as a …

Successful Extracorporeal Membrane Oxygenation In The Management Of Acute Respiratory Distress Syndrome And Cardiopulmonary Collapse Secondary To Amniotic Fluid Embolism, Sumon Roy, Nishit A. Biniwale, Venkata S. Pendela, Patricia Oates, Katrina Wojciechowski, Scott C. Feitell

The VAD Journal

Amniotic fluid embolism (AFE) is one of the most devastating complications of pregnancy that typically manifests as acute cardiopulmonary collapse during delivery or in the postpartum period. The potential role of extracorporeal membrane oxygenation (ECMO) as a management technique in severe cases of AFE remains largely unknown given the limited literature available. In this report, we present the first case, to our knowledge, of successful implementation of ECMO as a life-saving measure in a case of hemorrhagic shock due to postpartum bleeding complicated by severe AFE leading to acute respiratory distress syndrome (ARDS) ultimately requiring tracheostomy. Hemodynamic decompensation is often …
