Analysis Of Invariant Natural Killer T Cells In Intra-Abdominal Sepsis, Ram Venkatesh Anantha

Electronic Thesis and Dissertation Repository

Sepsis is characterized by a severe systemic inflammatory response to infection that is associated with high morbidity and mortality despite optimal care. Invariant natural killer T (iNKT) cells are potent regulatory lymphocytes that can produce pro- and/or anti-inflammatory cytokines, thus shaping the course and nature of immune responses; however, little is known about their role in sepsis. We demonstrate here that patients with sepsis/severe sepsis have significantly elevated proportions of circulating iNKT cells in their peripheral blood, as compared to non-septic patients. We therefore investigated iNKT cells in mice with intra-abdominal sepsis (IAS). Our data show that iNKT cells are …

Weight-Based Discrimination And Medication Adherence Among Low-Income African Americans With Hypertension: How Much Of The Association Is Mediated By Self-Efficacy?, Michael Richardson, Molly Waring, Monica Wang, Lisa Nobel, Yendelela Cuffee, Sharina Person, Sandral Hullett, Catarina Kiefe, Jeroan Allison

Monica L. Wang

OBJECTIVES: Much of the excessive morbidity and mortality from cardiovascular disease among African Americans results from low adherence to anti-hypertensive medications. Therefore, we examined the association between weight-based discrimination and medication adherence. METHODS: We used cross-sectional data from low-income African Americans with hypertension. Ordinal logistic regression estimated the odds of medication non-adherence in relation to weight-based discrimination adjusted for age, sex, education, income, and weight. RESULTS: Of all participants (n = 780), the mean (SD) age was 53.7 (9.9) years and the mean (SD) weight was 210.1 (52.8) lbs. Reports of weight-based discrimination were frequent (28.2%). Weight-based discrimination (but not …

Ponatinib-Induced Adverse Effects: Thrombocytopenia, Pancreatitis And Hepatoxicity-- A Case Report, Saba Hasan, Crystal Fedorkiv, Naba Rahman, Jennifer Andres

Research Day

Abstract: Chronic myeloid leukemia (CML) is a myeloproliferative disease that generates from malignant transformation of pluripotent hematopoietic stem cells. First line treatment for CML is the tyrosine kinase inhibitor (TKI), imatinib. For patients resistant or intolerant to imatinib, other TKIs, dasatinib, nilotinib, and ponatinib, are approved treatments. Patients who are resistant or intolerant to other agents are started on ponatinib as a last line option. Common adverse events of ponatinib are hypertension, dry skin, rash, abdominal pain, constipation, and nausea. More serious adverse effects include cardiovascular effects, fluid retention, pancreatitis, severe myelosuppression, and hepatotoxicity. Treatment for these adverse effects can …

Anterior Cervical Foraminotomy: Short Term Outcomes In Patients With Isolated Cervical Radiculopathy, Howard Eisenbrock, Mark Rivkin, Amir R. Dehdashti

Research Day

Intro: Anterior cervical foraminotomy (ACF) is a novel approach involving direct decompression of nerve from an offending agent without fusion. Historically, several anterior and posterior approaches were utilized to treat cervical radiculopathy. Anterior cervical discectomy necessitates fusion and is subject to adjacent segment disease as well as loss of ROM. Posterior laminoforaminotomy seldom allows for removal of disc fragment and is associated with higher postoperative pain.

Methods: Between May 2010 and March 2013, 16 patients with one or two level cervical spondylosis with radiculopathy without myelopathy who failed conservative therapies such as anti-inflammatory medications, physical therapy or injections underwent anterior …

Kyphotic Progression After Thoracolumbar Burst Fractures Treated Conservatively, With Mis, Or Via Open Approach, Mark Rivkin, Howard Eisenbrock

Research Day

Management of thoracolumbar burst fractures (AO A3) without neurological deficit is subject to debate in the literature. While TLICS provides guidance for injuries necessitating intervention, it makes little mention of best surgical approaches. Furthermore, intact patients with suspected posterior ligamentous complex injury (TLICS 4) compose an additional level of management uncertainty. Present study examined outcomes for TL burst fractures in neurologically intact patients with suspected disruption of the PLC treated with bracing, MIS, or open fixation and fusion.

Gp91ds-Tat, A Selective Nadph Oxidase Peptide Inhibitor, Increases Blood Nitric Oxide (No) Bioavailability In Bind Limb Ischemia And Reperfusion (I/R), Sydney Walker, Tyler Galbreath, Qian Chen, Robert J. Barsotti, H. Patel, William Chau, Lindon H. Young

Research Day

I/R injury induces cell death and organ dysfunction in part due to a burst of reactive oxygen species that occurs upon the reintroduction of oxygen into the ischemic area, leading to endothelial dysfunction: decreased blood NO and increased hydrogen peroxide (H2O2 ) levels. We’ve previously shown in isolated rat hearts subjected to I/R injury, gp91ds-tat attenuated cardiac contractile dysfunction and reduced infarct size compared to controls presumably by the inhibition of NADPH oxidase induced superoxide release. Superoxide can quench NO via the formation of peroxynitrite and also be converted to H2O2 in blood. We attempted to confirm this hypothesis using …

Mitoquinone (Mitoq) Exerts Antioxidant Effects Independent Of Mitochondrial Targeted Effects In Phorbol-12-Myristate-13-Acetate (Pma) Or N-Formyl-L-Methiony-L-Leucyl-L-Phenylalanine (Fmlp) Stimulated Polymorphonuclear Leukocyte (Pmn) Superoxide (So) Release, Matthew Lepera, D. Pesikan, J. Voeun, Kerry-Anne Perkins, Qian Chen, Robert J. Barsotti, Lindon H. Young

Research Day

MitoQ is a mitochondrial-targeted coenzyme Q antioxidant analog that dose-dependently restored cardiac function and reduced infarct size in isolated perfused rat hearts subjected to ischemia reperfusion (I/R). Moreover, mitoQ also dose-dependently attenuated PMA stimulated PMN superoxide (SO) release at the same concentration (10uM) as the cardioprotective dose. NADPH oxidase is the principle source of PMN SO release. We speculate that mitoQ may exert antioxidant effects independent of the mitochondria. Therefore, we hypothesized that inhibition of mitoQ on PMN-SO release will be similar as other coenzyme Q analogs: coenzyme Q1 and decylubiquinone without affecting cell viability. SO release was measured spectrophotometrically …

Insulin Pump Class: Back To The Basics Of Pump Therapy, Sara Wilson Reece, Cheryl Williams

Research Day

Insulin pump therapy is a common mechanism for insulin delivery in Type 1 diabetes mellitus as well as in some patients with Type 2 diabetes mellitus. At the Longstreet Clinic, approximately 3% of patients on insulin therapy utilize insulin pumps. After several patients on insulin pump therapy experienced severe hypoglycemic episodes while driving, the need for review of insulin pump survival skills were identified. The insulin pump class which was conducted in a small group setting reviewed all of the necessary survival skills for effective insulin pump therapy. Pre- and post-class hemoglobin A1c values and emergency room visits as well …

Center for Translational Medicine Faculty Papers

Abstract Aims: Mitochondrial Ca(2+) homeostasis is crucial for balancing cell survival and death. The recent discovery of the molecular identity of the mitochondrial Ca(2+) uniporter pore (MCU) opens new possibilities for applying genetic approaches to study mitochondrial Ca(2+) regulation in various cell types, including cardiac myocytes. Basal tyrosine phosphorylation of MCU was reported from mass spectroscopy of human and mouse tissues, but the signaling pathways that regulate mitochondrial Ca(2+) entry through posttranslational modifications of MCU are completely unknown. Therefore, we investigated α1-adrenergic-mediated signal transduction of MCU posttranslational modification and function in cardiac cells. Results: α1-adrenoceptor (α1-AR) signaling translocated activated proline-rich …

Does Cariogenic Streptococcus Mutans Play A Role In Cardiovascular Disease?, Brittany Burks

The Review: A Journal of Undergraduate Student Research

The link that exists between oral health and the entire well-being of the body is continuously becoming more emphasized. As illnesses such as cardiovascular disease become more prevalent, dentists and researchers have suggested that a link between the transfer of bacteria in the mouth into the blood stream plays a direct cause in onset of the disease in some patients. The American Dental Association has begun stressing the importance of preventive care techniques and also the importance of understanding the role the mouth plays in a multitude of processes that occur in the body. Streptococcus mutans, which is the …

Background: Osteoporosis is the most common bone disease in the United States, and it is particularly common among women with multiple sclerosis (MS). However, despite this association, the temporal relationship between these two conditions has not been previously studied. Data from the Women’s Health Initiative provides a unique opportunity to examine the risk of developing osteoporosis over time in individuals diagnosed with MS. Objective: The purpose of this study is to refine the relationship between MS and osteoporosis, clarifying the impact of environmental and pharmacologic factors on each condition, as well as addressing treatment and preventative efforts for a patient …

Sirt1 Deletion Leads To Enhanced Inflammation And Aggravates Endotoxin-Induced Acute Kidney Injury, Rong Gao, Jiao Chen, Yuxin Hu, Zhenyu Li, Shuxia Wang, Sreerama Shetty, Jian Fu

Toxicology and Cancer Biology Faculty Publications

Bacterial endotoxin has been known to induce excessive inflammatory responses and acute kidney injury. In the present study, we used a mouse model of endotoxemia to investigate the role of Sirt1 in inflammatory kidney injury. We examined molecular and cellular responses in inducible Sirt1 knockout (Sirt1-/-) mice and wild type littermates (Sirt1+/+) in lipopolysaccharide (LPS)-induced kidney injury. Our studies demonstrated that Sirt1 deletion caused aggravated kidney injury, which was associated with increased inflammatory responses including elevated pro-inflammatory cytokine production, and increased ICAM-1 and VCAM-1 expression. Inflammatory signaling such as STAT3/ERK phosphorylation and NF-κB activation was markedly elevated in kidney tissues …

Pediatric Asthma Telemonitoring: Literature, Theory, And Application To Practice, Erin Christine Shankel

DNP Scholarly Projects

Asthma is one of the most prevalent and costly chronic diseases faced by Americans today. It is marked by inflammation and hyperresponsiveness of the airways which fluctuates, often unpredictably, in response to triggers. As such, it causes particular challenges symptom management, especially on the part of the patient who is tasked with dealing with these frequent fluctuations for months at a time between regularly scheduled health care appointments. This is further complicated when the patient is a child, and symptoms must be interpreted and managed second-hand by a caregiver. Uncertainty about how to manage symptoms, as well as minimization of …

The Effect Of Patient Reminders On Osteoporosis Screenings, Billie-Ann Black

Evidence-Based Practice Project Reports

Osteoporosis is characterized by reduction of bone mass and compromised bone strength, resulting in an increased fracture risk. Since a reduction of bone mass has been shown to be predictive of future fracture risk, prevention strategies target screening those patients at risk for decreased bone mass by using bone mineral density (BMD) dual energy x-ray absorptiometry (DXA) scans. Current national guidelines recommend that all women 65 years and older undergo BMD testing using central DXA every two years. Despite these recommendations, women age 65 years and older still do not participate in this screening. Greater rates of osteoporosis screening could …

The Effects Of Education On Cardiovascular Disease Knowledge, Lauren A. Ostrowski-Winkler

Evidence-Based Practice Project Reports

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality for adults in the United States. The three main risk factors for the development of CVD include hypertension, high cholesterol, and tobacco use; these factors are largely prevented or reduced through lifestyle modifications. Researchers indicate that knowledge of CVD mortality has been linked with individual action to reduce one’s CVD risk. Researchers have also indicated that segments of our underserved society, particularly those with the highest CVD mortality rates, are also the least knowledgeable about CVD and their own personal risk. These risk factors were a concern within the …

Nanotoxicity In Cells Of The Immune System, Jonathan J. Pelc

Science Scholars

Nanoparticles (NPs) provide a new medical approach to drug therapy. As with every new approach, safety precautions need to be taken, and the immediate and long-term effects for many NPs are still unclear. When administering a medical treatment into the human body, the first issue that needs to be addressed is host detection of the medicine and inflammation as a possible result of the treatment. If a new NP treatment causes inflammation before it releases its medicine, that treatment may be ineffective, even damaging to the patient. Small metallic and organic particles have been shown to elicit an inflammatory responses …

Effects Of An Osteoporosis Educational Intervention: Knowledge And Self-Efficacy Of Prevention In Young Adult Collegiate Females, Valerie A. Bollenbacher

Evidence-Based Practice Project Reports

Osteoporosis is a silent and potentially debilitating chronic illness. In 2012, the CDC reported that 4.5 million women over the age of 50 were diagnosed with osteoporosis in the United States. Within the next 20 years, 41 million women worldwide are projected to have osteoporosis. The annual financial burden of osteoporosis is estimated to be 19 billion dollars. The objective of this evidence-based practice project was to answer the clinical question: In young adult collegiate females, how does an osteoporosis educational intervention compared to current education effect osteoporosis knowledge and self-efficacy of osteoporosis prevention over a one-month time period? The …
