Byrd, Maya Dangerfield

Capstones

In April 2015, William Byrd Wilkins or ‘Byrd’, 50, a theatre and television actor, was diagnosed with pancreatic cancer. In August, his friends crowd-funded an all expense paid trip to New York for Byrd who wasundergoing chemotherapy in his rural hometown of Louisburg, North Carolina. Originally described as ‘an opportunity to reconnect’ the trip soon developed into a ‘living funeral’ as Byrd and his friends grappled with Byrd’s terminal prognosis. As he visited his favorite New York haunts and met with friends, Byrd wrestled with the decision to end his chemotherapy upon his return home.

Steroid Receptor Isoform Expression In Drosophila Nociceptor Neurons Is Required For Normal Dendritic Arbor And Sensitivity, Aidan L. Mcparland, Taylor L. Follansbee, Gwendolyn D. Vesenka, Alexandra E. Panaitiu, Geoffrey K. Ganter

Biology Student Publications

Steroid hormones organize many aspects of development, including that of the nervous system. Steroids also play neuromodulatory and other activational roles, including regulation of sensitivity to painful stimuli in mammals. In Drosophila, ecdysteroids are the only steroid hormones, and therefore the fly represents a simplified model system in which to explore mechanisms of steroid neuromodulation of nociception. In this report, we present evidence that ecdysteroids, acting through two isoforms of their nuclear ecdysone receptor (EcR), modulate sensitivity to noxious thermal and mechanical stimuli in the fly larva. We show that EcRA and EcRB1 are expressed by third instar larvae in …

Progression Of Non-Alcoholic Steatosis To Steatohepatitis And Fibrosis Parallels Cumulative Accumulation Of Danger Signals That Promote Inflammation And Liver Tumors In A High Fat-Cholesterol-Sugar Diet Model In Mice, Michal Ganz, Terence N. Bukong, Timea Csak, Banishree Saha, Jin-Kyu Park, Aditya Ambade, Karen Kodys, Gyongyi Szabo

Gyongyi Szabo

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is becoming a pandemic. While multiple 'hits' have been reported to contribute to NAFLD progression to non-alcoholic steatohepatitis (NASH), fibrosis and liver cancer, understanding the natural history of the specific molecular signals leading to hepatocyte damage, inflammation and fibrosis, is hampered by the lack of suitable animal models that reproduce disease progression in humans. The purpose of this study was first, to develop a mouse model that closely mimics progressive NAFLD covering the spectrum of immune, metabolic and histopathologic abnormalities present in human disease; and second, to characterize the temporal relationship between sterile/exogenous danger …

Pathogen-Specific Burdens Of Community Diarrhoea In Developing Countries: A Multisite Birth Cohort Study (Mal-Ed), Sadia Shakoor, Shahida Qureshi, Furqan Kabir, Anita K. M. Zaidi, Zulfiqar Ahmed Bhutta, Imran Ahmed, Didar Alam, Syed Asad Ali, Muneera Rasheed, Sajid Bashir Soofi, Ali Turab, Aisha Khizar Yousafzai

Department of Pathology and Laboratory Medicine

Background: Most studies of the causes of diarrhoea in low-income and middle-income countries have looked at severe disease in people presenting for care, and there are few estimates of pathogen-specific diarrhoea burdens in the community.
Methods: We undertook a birth cohort study with not only intensive community surveillance for diarrhoea but also routine collection of non-diarrhoeal stools from eight sites in South America, Africa, and Asia. We enrolled children within 17 days of birth, and diarrhoeal episodes (defined as maternal report of three or more loose stools in 24 h, or one loose stool with visible blood) were identified through …

Microrna-155 Deficiency Attenuates Liver Steatosis And Fibrosis Without Reducing Inflammation In A Mouse Model Of Steatohepatitis, Timea Csak, Shashi Bala, Dora Lippai, Karen Kodys, Donna Catalano, Arvin Iracheta-Vellve, Gyongyi Szabo

Gyongyi Szabo

BACKGROUND and AIM: MicroRNAs (miRs) regulate hepatic steatosis, inflammation and fibrosis. Fibrosis is the consequence of chronic tissue damage and inflammation. We hypothesized that deficiency of miR-155, a master regulator of inflammation, attenuates steatohepatitis and fibrosis.

METHODS: Wild type (WT) and miR-155-deficient (KO) mice were fed methionine-choline-deficient (MCD) or -supplemented (MCS) control diet for 5 weeks. Liver injury, inflammation, steatosis and fibrosis were assessed.

RESULTS: MCD diet resulted in steatohepatitis and increased miR-155 expression in total liver, hepatocytes and Kupffer cells. Steatosis and expression of genes involved in fatty acid metabolism were attenuated in miR-155 KO mice after MCD feeding. …

Investigating The Mechanism Of Ectopic Mineralization In A Mouse Model Of Diffuse Idiopathic Skeletal Hyperostosis (Dish), Neil A. Tenn

Electronic Thesis and Dissertation Repository

Equilibrative nucleoside transporter 1 (ENT1) transfers adenosine across plasma membranes. Mice lacking ENT1 (ENT1^-/-) develop pathological calcification of spinal tissues resembling diffuse idiopathic skeletal hyperostosis (DISH) in humans. Our goal was to investigate the mechanism underlying ectopic mineralization in ENT1^-/- mice. We detected aberrant alkaline phosphatase (ALP, promoter of mineralization) activity in the annulus fibrosus (AF) of ENT1^-/- mice. In vitro, AF cells from ENT1^-/- mice exhibited greater ALP activity than cells from wild-type (WT) mice. Inhibition of ENT1 in the presence of extracellular adenosine modeled in WT cells the phenotype of ENT1 …

Chikungunya Virus: More Than A Mosquito Bite, Abigail Shaw

Nursing Student Class Projects (Formerly MSN)

Chikungunya fever is a viral infection caused by the Chikungunya virus (CHIKV). Although seldom fatal, CHIKV causes high fevers, polyarthralgia, and rash. The mosquito-borne virus has spread rapidly in the last ten years, causing over three million cases of CHIKV worldwide (Powers, 2015). The recent outbreak initiated in Africa and the islands of the Indian Ocean in 2004 has quickly spread to Asia, Europe and the Americas (CDC, 2015). According to the CDC (2015), until 2014, cases in the United States had only been linked to foreign travel outside of the Americas. As the outbreak has grown, cases of local …

Thrombotic Thrombocytopenia Purpura, Ann Oliva

Nursing Student Class Projects (Formerly MSN)

Patients with Thrombotic Thrombocytopenia Purpura, or TTP, are often times seen in the emergency department and subsequently admitted to the inpatient or the critical care unit. The problems that TTP patients can present with vary greatly and astute nursing assessment plus knowledge of the pathophysiology behind the diagnosis is vital to deliver excellent nursing care. Thrombotic Thrombocytopenia Purpura or TTP is a rare but potentially fatal condition that occurs as result of decreased levels of ADAMTS-13, a cleaving protease for von Willebrand factor (vWF), which causes platelet aggregation and microvascular thrombi and subsequent end-organ damage, along with thrombocytopenia, hemolytic anemia, …

Malignant Hyperthermia: A Clinical Crisis, Eric Reing

Nursing Student Class Projects (Formerly MSN)

Malignant hyperthermia, though uncommon, is a serious and life threatening condition. Malignant hyperthermia is an autosomal dominant disorder that affects skeletal muscle. It can be caused by various general anesthetic agents like succinylcholine and several inhaled anesthetics. Malignant hyperthermia is a relevant topic to certified registered nurse anesthetists due to the potentially fatal result if not recognized and treated promptly. In understanding the pathophysiology, risk factors, signs and symptoms, epidemiology, and current treatments the health care provider can help to prevent complications due to this disorder (Nagelhout, 2014).

Preparedness Of Nurses For Malignant Hyperthermia, Melissa Flemming

Nursing Student Class Projects (Formerly MSN)

Malignant hyperthermia (MH) is a potentially life threatening disorder that occurs following exposure to certain inhaled anesthetics such as halothane, isoflurane, sevoflurane, desflurane, enflurane, ether, and methoxyflurane alone or in combination with the depolarizing muscle relaxant, succinylcholine (Seifert,, Wahr, Pace, Cochrane, & Bagnola, 2014, p. 189). Patients experiencing malignant hyperthermia may progress to death if it is not recognized and treated early. Patient outcomes improve the earlier an intervention is given. Malignant hyperthermia is not a common condition and, therefore, nurses are frequently unfamiliar with the common signs, symptoms, and treatments. Malignant hyperthermia can occur in a variety of settings …

What You Need To Know About Malignant Hyperthermia, Regan C. Siegman

Nursing Student Class Projects (Formerly MSN)

The first case of malignant hyperthermia (MH) that can be identified dates back to the 1960s when a patient with a known familial history of anesthesia complications demonstrated tachycardia, increased body temperature and hypotension following induction of anesthesia. After this incident, clinicians described MH as an increased metabolic state that has a range of signs associated with induction of inhaled anesthetics (Seifert, Wahr, Pace, Cochrane, & Bagnola, 2014). MH is a serious, life-threatening reaction that occurs after being exposed to certain inhaled and local anesthetics. Some of the inhaled volatile anesthetic agents that can trigger MH include halothane, sevoflurane, desflurane …

Neuroleptic Malignant Syndrome: A Pathophysicological Dilemma, Samantha Davis

Nursing Student Class Projects (Formerly MSN)

Neuroleptic malignant syndrome (NMS) is a rare disease occurring from an adverse reaction to anti-psychotic use. The diagnosis and predictability of the disease is extremely difficult as it mimics other syndromes (Margetić & Aukst-Margetić, 2010). The disease onset can occur when initiating medications, escalating doses, or adding an adjunctive anti-psychotic to the regimen. Although causing the unpredictability, the disease can occur at any dose (Paul, Michael, John, & Lenox, 2012). Further increasing the difficulty of diagnostics, signs and symptoms are very wide spread. The Diagnostic and Statistical Manual of Mental Disorders created a tool to assist in the clinical setting; …

Raynaud’S Phenomenon, Sarah Gasper

Nursing Student Class Projects (Formerly MSN)

Raynaud’s phenomenon (RP) is a widely prevalent clinical disorder commonly seen in outpatient settings. It is characterized by episodic vasospastic attacks of the digital arteries and arterioles that limit blood flow to the extremities, causing severe pain. Temperature changes and stress are the primary triggers that exacerbate this disease. The classic biphasic color changes of RP are pallor, cyanosis, and erythema and commonly affect the fingers and toes and more rarely, the nose, nipples, ears, lips, and penis. RP is divided into subcategories. Primary Raynaud’s phenomenon (PRP) is when no underlying medical disease exists and the condition happens spontaneously. It …

The Plight Of The Lucluc: Examining The Deadly Mystery Of Nodding Syndrome, Ethan K. Mcgann

Senior Honors Theses

Nodding syndrome (NS) is an emerging epidemic neurological disease that is shrouded in mystery. It is currently only found in the post-conflict regions of South Sudan, northern Uganda, and Tanzania. NS occurs in children from the ages of five to fifteen and is characterized by a loss of motor control in the neck muscles. Seizure episodes can range in intensity from atonic to tonic-clonic, and the onset of the first episode generally marks the beginning of a decline in the child’s physical and mental health. NS is a progressive disease that generally results in physical wasting, stunted growth, behavioral difficulties, …

Leukoaraiosis And Sex Predict The Hyperacute Ischemic Core Volume, Nils Henninger, Eugene Lin, Diogo Haussen, Laura Lehman, Deepak Takhtani, Magdy Selim, Majaz Moonis

Nils Henninger

BACKGROUND AND PURPOSE: Leukoaraiosis (LA) and male sex have been associated with decreased cerebrovascular reactivity, which potentially adversely affects tissue viability in acute stroke. Therefore, we aimed to elucidate the contribution of LA-severity and sex to the extent of the hyperacute ischemic core volume after intracranial large artery occlusion. METHODS: We analyzed data from 87 patients with acute intracranial large artery occlusion who had acute multimodal computed tomography-imaging. LA-severity was assessed using the van Swieten scale on noncontrast computed tomography. Computed tomography perfusion data were analyzed using automatic calculation of the mean transit time and hyperacute cerebral blood volume defects. …

Severity Of Pre-Existing Cerebral Small Vessel Disease Is Associated With Outcome After Traumatic Brain Injury, Nils Heninger, Saef Izzy, Raphael Carandang, Wiley Hall, Susanne Muehlschlegel

Nils Henninger

Background and purpose: It is now well accepted that traumatic white matter injury constitutes a critical determinant of post-traumatic functional impairment. However, the contribution of pre-existing white matter rarefaction on outcome following traumatic brain injury (TBI) is unknown. Hence, we sought to determine whether the burden of pre-existing cerebral small vessel disease related white matter rarefaction (leukoaraiosis) is independently associated with outcome after TBI. Methods: We retrospectively analyzed consecutive, prospectively enrolled patients of ≥50 years (n=136) that were admitted to a single neurological-trauma intensive care unit. Supratentorial white matter hypoattenuation on head CT was graded on a 5-point scale (range …
