Gliopathy Of Demyelinating And Non-Demyelinating Strains Of Mouse Hepatitis Virus., Lawrence C. Kenyon, Kaushiki Biswas, Kenneth S Shindler, Manasi Nabar, Marjorie Stout, Susan T Hingley, Judith B Grinspan, Jayasri Das Sarma

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Demyelination in the central nervous system induced by neurovirulent strains of Mouse Hepatitis Virus (MHV) is mediated by the viral spike glycoprotein, but it is not clear whether the mechanism of this disease pathology involves direct viral infection of oligodendrocytes. Detailed studies of glial cell tropism of MHV are presented, demonstrating that direct MHV infection of oligodendrocytes differs between demyelinating (RSA59) and non-demyelinating (RSMHV2) viral strains both in vitro and in vivo. Our results indicate that direct injury of mature oligodendrocytes is an important mechanism of virus-induced demyelination. In vivo, RSA59 infection was identified in spinal cord gray and white …

Metastatic Brain Tumors: Current Therapeutic Options And Historical Perspective, Mark Rivkin, Richard Kanoff

Mark Rivkin

Metastatic brain tumors affect more than 150,000 patients annually in the United States. The therapeutic paradigms for these tumors have evolved over the years and currently encompass numerous modalities implemented by treating physicians across several medical disciplines. The armamentarium of brain tumor treatment involves neurosurgical intervention, whole-brain and focused radiation modalities, chemotherapy, and immunotherapy. Patient selection, however, remains critical to achieve maximal therapeutic benefit and depends on functional status, number and location of lesions, and tissue histologic findings. Best outcomes can be expected with a multidisciplinary approach to patient care where state-of-the-art treatment options are readily available.

Progtar: A Database Of Prognostically Inversely Correlated Mirnas And Genes (Pics) In Multiple Cancers, Chirayu Pankaj Goswami

Department of Pathology, Anatomy, and Cell Biology Posters

ABSTRACT

PROGTar is a database of Prognostically Inversely Correlated miRNA-mRNA pairs (PIC’s) in 23 cancer types. Partner miRNA and mRNA in a PIC show inverse correlation of expression and opposite hazards. We analyzed miRNA and mRNA expression data downloaded from The Cancer Genome Atlas (TCGA) in a 3 step approach to identify PICs in different cancer types. In first step we performed correlation analysis between miRNAs and mRNAs for each cancer type. This was followed by performing hazard analysis separately for miRNAs and mRNAs using expression data and survival related clinical variables. In the third step we merged the correlation …

Department of Pathology, Anatomy, and Cell Biology Resident's Posters

Background:

Metaplastic breast carcinoma (MBC) is a rare subtype of breast carcinoma less responsive to conventional chemotherapy relative to usual breast carcinomas such as ductal and lobular subtype. In molecular terms, MBC usually clusters with triple negative breast cancers (TNBC), but MBCs portray a worse prognosis in comparison with TNBC. Published studies investigating MBCs for specific biomarkers of therapy response are rare and limited by the methodological approaches.

Methods:

297 samples [MBC (n=75), triple-negative breast cancer of no-special-type (TNBC-NOS, n=106), HER2-positive breast cancers (n=32) and luminal breast cancers (n=84)] were profiled using direct sequencing analysis [Illumina MiSeq Next Generation Sequencing …

Fair Weight Loss After Gastric Rebanding For Slippage, Ahmed Dalmar, Maharaj Singh, Sara K. Roloff, Thomas Y. Chua

Journal of Patient-Centered Research and Reviews

Background: Laparoscopic adjustable gastric banding (LAGB) is one of the most common bariatric surgery procedures performed in the United States. LAGB results in safe and satisfactory weight loss, but it is often complicated with slippage, a complication requiring rebanding (reoperation). There is a paucity of studies and no uniform consensus regarding weight loss after rebanding.

Purpose: This study assessed the effect of rebanding for slippage after LAGB on weight loss up to five years.

Methods: This is a historical cohort study of 865 patients who underwent LAGB from 2001 to 2011. Rebanding was performed in 103 (11.9%) patients. Primary outcome …

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Rearrangements of 3q26 have been described in 5% of de novo or therapy related acute myeloid leukemia, myelodysplastic syndrome (MDS), and blast phase of chronic myeloid leukemia. The most common translocations involving 3q26 are t(3;12)(q26;p13), t(3;21)(q26;q22), t(3;3)(q21;q26), t(2;3)(p15∼23;q26∼27) and rarely t(3;7)(q26;q21). However, t(3;8)(q26;q24) with or without monosomy 7 is a rare phenomenon and has been reported in only 10 patients so far. Hereby, we describe a 58 year old patient who was diagnosed with refractory anemia with multilineage dysplasia. Cytogenetic studies revealed monosomy 7. He was then lost to follow-up. A year later he was found to have worsening cytopenias …

Cross-Sectional Survey Of Relevant Literatures As To The Current Proposed Disease Mechanisms And Treatments Of Amyotrophic Lateral Sclerosis (Als), Zachary Sanford

Marshall Journal of Medicine

Amyotrophic Lateral Sclerosis (ALS), more commonly referred to as Lou Gehrig’s disease, is a progressively degenerative neuromuscular disorder affecting both the upper and lower motor neurons and preferentially affecting males in their forties to seventies. Although the pathology of ALS has been clearly elucidated elsewhere, the precise mechanisms by which the disease progresses and the means by which it is acquired are still poorly understood areas of medicine. Current genomic and proteomic studies in human and animal models have yielded exciting and promising new findings that may help elucidate this pathology. It is the purpose of this review article to …

The Role Of Perlecan And Endorepellin In The Control Of Tumor Angiogenesis And Endothelial Cell Autophagy., Stephen Douglass, Atul Goyal, Renato V. Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

During tumor growth and angiogenesis there is a dynamic remodeling of tissue architecture often accompanied by the release of extracellular matrix constituents full of biological activity. One of the key constituents of the tumor microenvironment is the large heparan sulfate proteoglycan perlecan. This proteoglycan, strategically located at cell surfaces and within basement membranes, is a well-defined pro-angiogenic molecule when intact. However, when partially processed by proteases released during cancer remodeling and invasion, the C-terminal fragment of perlecan, known as endorepellin, has opposite effects than its parent molecule. Endorepellin is a potent inhibitor of angiogenesis by exerting a dual receptor antagonism …

Sanders-Brown Center on Aging Faculty Publications

ABCC9 genetic polymorphisms are associated with increased risk for various human diseases including hippocampal sclerosis of aging. The main goals of this study were 1 > to detect the ABCC9 variants and define the specific 3′ untranslated region (3′UTR) for each variant in human brain, and 2 > to determine whether a polymorphism (rs704180) associated with risk for hippocampal sclerosis of aging pathology is also associated with variation in ABCC9 transcript expression and/or splicing. Rapid amplification of ABCC9 cDNA ends (3′RACE) provided evidence of novel 3′ UTR portions of ABCC9 in human brain. In silico and experimental studies were performed focusing on …

Ceramides Promote Apoptosis For Virus-Infected Lymphoma Cells Through Induction Of Ceramide Synthases And Viral Lytic Gene Expression, Lu Dai, Jimena Trillo-Tinoco, Aiping Bai, Yihan Chen, Jacek Bielawski, Luis Del Valle, Charles D. Smith, Augusto C. Ochoa, Zhiqiang Qin, Chris Parsons

School of Medicine Faculty Publications

Kaposi's sarcoma-associated herpesvirus (KSHV) is the etiologic agent for several human cancers including primary effusion lymphoma (PEL), a rapidly progressive malignancy arising preferentially in immunocompromised patients. With conventional chemotherapy, PEL continues to portend high mortality, dictating the development of novel therapeutic strategies. Sphingosine kinase 2 (SphK2) represents a key gatekeeper for sphingolipid metabolism, responsible for conversion of ceramides to sphingosine-1-phosphate (S1P). We have previously demonstrated that targeting SphK2 using a novel selective inhibitor, ABC294640, leads to intracellular accumulation of ceramides and induces apoptosis for KSHV-infected PEL cells, while suppressing tumor progression in vivo. In the current study, we sought to …

Myasthenia Gravis, Abbe R. Feaver

Nursing Student Class Projects (Formerly MSN)

Myasthenia gravis (MG) is a chronic autoimmune neuromuscular disease characterized by ocular, bulbar, facial, and skeletal muscle weakness due to a defect in the transmission of nerve to muscle impulses at the neuromuscular junction (Mestecky, 2013, p. 110). Approximately 14-20 in 100,000 people are diagnosed with myasthenia gravis in the United States (Leis, Moore, Kofler, Beric, De Visser, 2014, p. 112). Typically, diagnosis occurs in middle-aged adults with women generally acquiring the disease at a younger age than men (Mestecky, 2013, p. 110). MG has the potential to greatly affect the quality of life of a patient. Although the disease …

Nursing Student Class Projects (Formerly MSN)

Neurocysticercosis (NCC) is one of the most common parasitic infections of the central nervous system in humans and is the most serious clinical manifestation of cysticercosis. NCC is caused by the ingestion of the larval form of the pork tapeworm Taenia solium. NCC is endemic in low income developing countries where pigs are commonly raised, including the countries of Central America, South America, and parts of Africa and Asia. (Naddaf, Seeger, & Stafstrom, 2014). The parasite Taenia solium encysts in the brain and can express a broad range of symptoms including seizures, headache, hydrocephalus, encephalitis, stroke and mental health and …

Prevalence Of Sepsis In Pediatric Populations, Brittany Barnes

Nursing Student Class Projects (Formerly MSN)

Sepsis and more specifically septic shock in the pediatric population is a diagnosis that is full of complexities. There are instances where a neutropenic oncology patient observes a better outcome than a previously healthy patient who is suffering from the same pathogen related sepsis. Sepsis is the 10th leading cause of death according to the Center for Disease Control and Prevention, and each year between 20,000 and 42,000 children are diagnosed with severe sepsis (Riley & Wheeler, 2012). Even with significant advances in medical treatment, sepsis is still associated with high morbidity and mortality rates. A retrospective study of patient …

Marfan Syndrome In Athletes, Chelsey Hastings

Nursing Student Class Projects (Formerly MSN)

Genetic disorders are widely misunderstood in our society and can lead to early mortality. Marfan syndrome (MFS) is a genetic disorder that affects connective tissue (Harris, Croce, & Tian, 2014). Antoine Marfan, a French pediatrician, first described this disease in 1896 (Elshershari & Harris, 2014). MFS can manifest in several different organ systems. The cardiovascular complications of aortic dilation and dissection often account for the morbidity associated with this disease (Harris et al., 2014). Understanding the inheritance, pathophysiology, and treatment of MFS is important for the advanced practice nurse (APN). Prevalence of the disease is approximately two per 10,000 individuals, …

Granulomatosis With Polyangiitis (Wegner’S) : Often Mistaken For Tuberculosis, Dawn Palumbo

Nursing Student Class Projects (Formerly MSN)

The exact cause of GPA has yet to be identified. Dinić et al. (2013) defines GPA/WG as “anti-neutrophil cytoplasmic antibodies (ANCAs)- associated systemic vasculitis of unknown etiology” (p. 887). According to Alam, Dastider, Ahmed, and Rabbani (2012) both cellular and humoral immunity are thought to be involved in the pathogenesis of wegener’s granulomatosis. “ The initial pathologic lesion is granuloma believed to be caused by cellular immune process. The strong association on C-ANCA with this disease suggests the role of humoral immunity” (Alam et al., 2014, p. 98). Huang et al. (2013) suggest, “The main pathological features of limited Wegeners’ …

Nursing Student Class Projects (Formerly MSN)

Basal cell carcinoma (BCC) is a nonmelanoma skin cancer. According to the Skin Cancer Foundation, “BCC is the most frequently occurring form of all skin cancers. More than one out of every three new cancers is a skin cancer, and the vast majority are BCC’s” (www.skincancer.org). Exposure to ultraviolet (UV) rays is one of the main risk factors in developing a BCC. People with a lighter skin tone are at a higher risk of developing a BCC than those with a darker skin tone.

Nash: Non-Alcoholic Steatohepatitis, Jennifer Heck

Nursing Student Class Projects (Formerly MSN)

Non-alcoholic fatty liver disease (NAFLD) is a chronic liver disease which refers to the presence of hepatic steatosis without significant intake of alcohol. Non-alcoholic fatty liver disease develops in a variety of forms from reversible simple steatosis to non-alcoholic steatohepatitis (NASH), which if left unchecked can progress to liver fibrosis, cirrhosis and even develop into hepatocellular carcinoma (Mells et al., 2014). NAFLD is thought to be nonthreatening, but with progression over several years could lead to NASH. A strong link between obesity and NASH has been shown. In addition to obesity, insulin resistance (type II diabetes mellitus), and hyperlipidemia all …

Nursing Student Class Projects (Formerly MSN)

Atrial fibrillation (afib) is the most common sustained cardiac arrhythmia and second most common cardiovascular condition in adults in the United States (Zarraga & Kron, 2012). •2.2 million affected, increases risk of stroke 4 to 6 times (National Institute of Neurological Disorders and Stroke [NINDS], 2015). •Vitamin K antagonists (VKAs) have been mainstay of therapy for over 60 years (King, Holley& Moores, 2013). •Limitations with VKAs such as variability in response, need for frequent lab draws, food and drug interactions which decrease patients adherence and under prescribing by physicians (Halperin & Goyette, 2012). •Novel oral anticoagulants (NOACs) have been approved …

The Importance Of Evaluation And Management Of Sepsis, Severe Sepsis, And Septic Shock, Katherine Herda

Nursing Student Class Projects (Formerly MSN)

Sepsis is a life-threatening and complicated host response to the presence of infection that is affecting millions of individuals around the world each year (Dellinger et al., 2013, p. 583). According to Gray et al. (2013), sepsis is not only one of the primary causes of hospital admission but it is also a leading cause of morbidity and mortality worldwide (p. 397). Severe sepsis and septic shock are the more advanced and detrimental stages of sepsis, which are starting to increase in incidence and are killing one in four (and sometimes more) individuals infected (Dellinger et al., 2013, p. 583). …

Nursing Student Class Projects (Formerly MSN)

Gout is a syndrome caused by an inflammatory response creating an over production of uric acid increasing uric acid levels in the blood and body fluids. Gout is defined as a disorder resulting from tissue deposition of MSU crystals (in joints, bursae, bone, and certain other soft tissues, such as ligaments, tendons and occasionally, skin) and/or crystallization of uric acid within the renal collecting system (tubules and renal pelvis) that typically occurs in acid urine” (Terkeltaub & Edwards, 2013, p. 20). Gout is among the oldest diseases affecting approximately 3.9% of adults in America (Terkeltaub & Edwards, 2013, p. xv). …

Diabetic Ketoacidosis, Mario Bianconi

Nursing Student Class Projects (Formerly MSN)

According to “Statistics About Diabetes” (2014), in 2012, 29.1 million Americans, or 9.3% of the population, had diabetes. Additionally, of the 29.1 million, 21 million of the population were diagnosed, and 8.1 million were undiagnosed. With such a high prevalence, it is imperative that the hospital nurse is aware not only how to treat diabetes, but also how to look for complications of diabetes. One of the severe complications of diabetes is Diabetic Ketoacidosis, or DKA. DKA occurs as a result of prolonged untreated diabetes. It is the result of the body not being able to produce, or use, insulin …

Nursing Student Class Projects (Formerly MSN)

Environmental lead exposure is a pertinent public health risk that affects our rural population in Wyandot County, Ohio. Children exposed to lead hazards through toys, home remodeling and contaminated soil and water are at a greater risk for developing neurological, cognitive and behavioral issues than are children not exposed to lead (Cecil et al., 2011). Wyandot County parents are not adequately educated on the risks and consequences of elevated blood lead levels in their children. As a child advocate and director of the Women, Infant and Children program for Wyandot County there is an obligation to educate and inform parents …

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 …

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 …

Multiple Sclerosis (MS) is an autoimmune process characterized by inflammation and demyelination of axons in the brain and spinal cord (Schneider, 2005). According to Maclean (2010), MS is one of the most common debilitating neurological disorders in young adults. My intent of this research project is to explain the pathophysiological process and become familiar with the implications of anesthesia related to MS. This research will enable me to prepare a safe, individualized anesthetic plan, taking all essential precautions when caring for a patient with multiple sclerosis.

Takotsubo Cardiomyopathy, Angela J. Occidental

Nursing Student Class Projects (Formerly MSN)

Takotsubo cardiomyopathy is a rare, reversible form of cardiomyopathy. First cases of takotsubo cardiomyopathy were described in Japan, twenty years ago (Milinis, & Fisher, 2012). takotsubo cardiomyopathy is a transient left ventricular dysfunction, typically triggered by severe emotional or physical distress. Left ventricular ballooning is characteristic of Takotsubo syndrome. Images of this ballooning resemble a takotsubo vessel used in Japan for collecting octopus, thus the reason for the syndrome name (Pelliccia, et. al, 2014). In recent years, this cardiomyopathy has been described as “Broken heart syndrome” because severe emotional stress has been implicated as the cause of this cardiomyopathy in …
