Adult Pulmonary Langerhans Cell Histiocytosis With Osseous Involvement: Understanding This Rare Mimic Of Malignancy, Samantha A. Smith Ms Iii, Adam M. Franks Md, William Rollyson Ms Iv, Doreen Griswold, Tammy Bannister Md

Marshall Journal of Medicine

Langerhans cells are dendritic cells that form the antigenic barrier of the human body. They occur in nearly any tissue but are most prevalent in the skin, submucosa of the bronchial tree, and other mucosae. Langerhans Cell Histiocytosis (LCH) develops when these cells damage the tissues in which they reside through a combination of inflammatory and monoclonal stimulation. The pulmonary variant of LCH involves the lung parenchyma and creates a wide variety of disturbances: pulmonary hypertension and both obstructive and restrictive lung disease. Osseous involvement, in addition to the pulmonary variant, presents with pulmonary masses and lytic bone lesions, which …

Selective Gsk3Β Inhibition Mediates An Nrf2-Independent Anti-Inflammatory Microglial Response, Mohamed H. Yousef

Theses and Dissertations

Glycogen Synthase Kinase 3 (GSK3) is associated with the proinflammatory phenotype of microglia and has been shown to act in concert with Nuclear factor kappa B (NF-κB). . GSK3 is also a suppressor of Nuclear factor erythroid 2-related factor 2 (Nrf2), the principal regulator of redox homeostasis. Agreeing with the oxidative paradigm of aging, Nrf2 is often deregulated in parainflammatory and neurodegenerative diseases. In this study, we aimed to explore a multimodal disease-modifying utility of GSK3 inhibition, beyond neuronal proteopathologies, Furthermore, we aimed to underscore the difference in therapeutic value between the two GSK3 paralogs by isoform-selective chemical inhibition.

Continuing Medical Education On Immunothombosis In Sepsis, Vivienne Van Nguyen

Capstone Showcase

In the past decades, the incidence of sepsis complicated by immunothrombosis has increased in critically ill patients, especially those with sepsis and septic shock. Despite intensive surveillance and prevention of the underlying causes, these disease syndromes are frequently fatal. The increased incidence of immunothrombosis in sepsis has been accompanied by many critical issues and concerns regarding current diagnostic and treatment protocols. This paper offers a concise critical assessment of the current state of knowledge about sepsis and immunothrombosis among clinicians in the ICU as well as problem concerning the recognition of sepsis and immunothrombosis and their management.

The Effects Of Glucocorticoids And Immunosuppressants On Cancer Outcomes In Checkpoint Inhibitor Therapy, Sebastian Bruera, Maria E Suarez-Almazor

Faculty, Staff and Students Publications

The emergence of checkpoint inhibitors has created a paradigm shift for the treatment of various malignancies. However, although these therapies are associated with improved survival rates, they also carry the risk of immune-related adverse events (irAEs). Moderate to severe irAEs are typically treated with glucocorticoids, sometimes with the addition of immunosuppressants as steroid-sparing therapy. However, it is unclear how glucocorticoids and immunosuppressants may impact cancer survival and the efficacy of immune checkpoint therapy on cancer. In this narrative review, we discuss the effects of glucocorticoids and immunosuppressants including methotrexate, hydroxychloroquine, azathioprine, mycophenolate mofetil, tumor-necrosis factor (TNF)-inhibitors, interleukin-6 inhibitors, interleukin-1 inhibitors, …

Effects Of Gaba On Inflammation And Intestinal Barrier Disruption, Tyrel W. Long

EWU Masters Thesis Collection

Gut dysbiosis and intestinal barrier disruption have been linked to multiple sclerosis (MS). Our previous works show that experimental autoimmune encephalomyelitis (EAE) induction modifies the gut's microbiota composition, reducing frequencies of gamma-aminobutyric acid (GABA)-producing bacteria. GABA levels are reduced in the brains and circulation of MS patients. We engineered Lactococcus lactis with extra copies of gadB (glutamic acid decarboxylase) and gadC (glutamate/GABA antiporter) to increase GABA levels produced by the bacterium (GAD-L. lactis). EAE studies showed that the treatment with GAD-L. lactis and not with a L. lactis control expressing an empty plasmid (P-L. lactis) reduced the severity of the …

Evaluating The Efficacy Of Automated Smoking Treatment For People With Hiv: Protocol For A Randomized Controlled Trial, Damon J Vidrine, Thanh C Bui, Michael S Businelle, Ya-Chen Tina Shih, Steven K Sutton, Lokesh Shahani, Diana Stewart Hoover, Kristina Bowles, Jennifer I Vidrine

Faculty, Staff and Student Publications

BACKGROUND: Smoking prevalence rates among people with HIV are nearly 3 times higher than those in the general population. Nevertheless, few smoking cessation trials targeting smokers with HIV have been reported in the literature. Efforts to develop and evaluate sustainable, low-cost, and evidence-based cessation interventions for people with HIV are needed. Given the widespread proliferation of mobile phones, the potential of using mobile health apps to improve the reach and efficacy of cessation interventions is promising, but evidence of efficacy is lacking, particularly among people with HIV.

OBJECTIVE: This study will consist of a 2-group randomized controlled trial to evaluate …

Anti-Vaxxers: Parents Fighting Science, Katie West

Symposium of Student Scholars

Immunizing children helps protect the health of our community, especially those people who cannot be immunized. Yet, since 1996 after a study was released that linked autism to vaccinations, there has been a trend of parents refusing to vaccinate their children. What are the demographics of the parents who believe their children are better off without vaccines? By knowing where these parents live and what decisions they make for their children’s education, counties and medical professionals can provide education and address their concerns.

My research involves data on 116,141 kindergarten classes from 2000-2015 in California. The two vaccine exemption options …

Osteoporosis Implications For The Aging Adult, Grace Alford

Nursing Student Class Projects (Formerly MSN)

This poster describes the pathophysiology, symptoms, implications for care, and treatment of osteoporosis for advanced practice RNs. The research was conducted within health-related databases. The literature review narrowed the search to only include the pathophysiology, interventions, and care for osteoporosis. Literature was restricted to within the past five years. The research showed that osteoporosis reduces mineral density in bones and can be adequately treated within a short amount of time. It is important for nurses and advanced practice providers to be aware of current guidelines, screenings, and treatments for osteoporosis.

Trichomonas vaginalis is a prevalent sexually transmitted infection (STI). Diagnosis has historically relied on either microscopic analysis or culture, the latter being the previous gold standard. However, these tests are not readily available for male diagnosis, generally only perform well for symptomatic women, and are not as sensitive as nucleic acid amplification tests (NAATs). Men are largely asymptomatic but carry the organism and transmit to their sexual partners. This multicenter, prospective study evaluated the performance of the cobas T. vaginalis/Mycoplasma genitalium (TV/MG) assay for detection of T. vaginalis DNA compared with patient infection status (PIS) defined by a combination of …

Acute Encephalitis, Myoclonus And Sweet Syndrome After Mrna-1273 Vaccine, Gabriel Torrealba-Acosta, Jennifer C Martin, Yve Huttenbach, Catherine R Garcia, Muhammad R Sohail, Sandeep Krishna Agarwal, Carina Wasko, Eric M Bershad, Mohammad I Hirzallah

Faculty, Staff and Students Publications

A patient presented with fever, generalised rash, confusion, orofacial movements and myoclonus after receiving the first dose of mRNA-1273 vaccine from Moderna. MRI was unremarkable while cerebrospinal fluid showed leucocytosis with lymphocyte predominance and hyperproteinorrachia. The skin evidenced red, non-scaly, oedematous papules coalescing into plaques with scattered non-follicular pustules. Skin biopsy was consistent with a neutrophilic dermatosis. The patient fulfilled the criteria for Sweet syndrome. A thorough evaluation ruled out alternative infectious, autoimmune or malignant aetiologies, and all manifestations resolved with glucocorticoids. While we cannot prove causality, there was a temporal correlation between the vaccination and the clinical findings.

Oral Manifestations Of Tuberculosis, Diana V. Macri, Sandra Castellanos, Elvir Dincer

Publications and Research

This article will update the reader on tuberculosis and its oral manifestations.

After decades of decreasing incidence, tuberculosis resurgence is being seen in some global regions due to factors that include the human immunodeficiency virus (HIV) epidemic, increased immigration from countries with endemic tuberculosis, transmission of tuberculosis in crowded or unsanitary environments, and poor healthcare infrastructure. Additionally, this review is especially prescient considering the increasing prevalence of drug-resistant tuberculosis.

Assessment Of Pathogenic Changes In The Gut-Liver Axis In Plwh With Heavy Alcohol Drinking And Gut Dysbiosis Marked By Decreased Butyrogenic Potential., Smita Ghare, Vaughn Bryant, Richa Singhal, Sabina Gautam, Chanakya Charan Tirumala, Andrea Reyes-Vega, Craig J. Mcclain, Ronald Cohen, Varand Govind, Robert L. Cook, Shirish Barve

Faculty and Staff Scholarship

Purpose: People living with HIV infection (PLWH) experience increasing risk for non-AIDS diseases including liver dysfunction and injury. Both HIV-infection and heavy alcohol drinking (HAD) are known to cause gut microbial dysbiosis and systemic inflammation that may potentially contribute to altered Gut-Liver axis. However, the specific pathogenic features associated with combinatorial harmful effects of alcohol and HIV infection on gut-liver interactions are not completely understood. This study evaluate the pathogenic changes in the Gut-Liver axis in PLWH with HAD.

Diabetes Mellitus And Immunomodulation: A Double-Edged Sword., James Harte

International Undergraduate Journal of Health Sciences

Diabetes is an endocrinological disorder characterised by chronic hyperglycaemia due to abnormalities in insulin secretion, insulin action or a combination of both. According to the International Diabetes Federation, 463 million people worldwide are living with diabetes; 700 million people will be affected by 2045. The severity of the disease is dependent on the type and the stage of progression; when not correctly managed, diabetes can lead to potentially life-threatening micro- and macrovascular complications.

Prior to the discovery of insulin in 1922, the life expectancy of children with diabetes was short and the prognosis was very poor. The advocated treatment for …

The Effect Of Carfilzomib And Bortezomib Based Regimes On Cardiotoxicity In Multiple Myeloma Patients At Cooper University Hospital, Ami Patel, Tulin Budak-Alpdogan, Stalam Tapati

Rowan-Virtua Research Day

Introduction

• Multiple myeloma (MM) is a cancer of plasma cells, which is a white blood cell that normally produces antibodies
• Treatment in patients younger than 65 years old is typically high dose chemotherapy, usually with bortezomib based regimens or lenalidomide dexamethasone, followed by a stem cell transplant
• For patients with relapsed myeloma, carfilzomib is usually the treatment of choice
• Carfilzomib is a highly selective, irreversible proteasome inhibitor that binds to the 20 S proteasome. Several studies have illustrated that carfilzomib has been associated with cardiovascular adverse events (CVAE).
• Current literature on the role and effect of bortezomib on cardiotoxicity is …

Simian Varicella Virus Antibody Response In Recombinant Svv-Siv Immunized Primates, Kiser Horne

Honors Theses

Since its emergence in the early 1980’s HIV has killed approximately 32 million people, and continues to kill over half a million people every year. Significant research into potential vaccines and cures for HIV has been ongoing for decades but has been largely unsuccessful. One of the more promising technologies that is being investigated to develop an HIV vaccine is recombinant vaccine technology. The study presented in this thesis aims to use simian varicella virus (SVV) and simian immunodeficiency virus (SIV) to act as a model for recombinant vaccine development. If a recombinant SVV-SIV vaccine can be proven safe and …

Identification And Characterization Of Butyrate-Producing Species In The Human Gut Microbiome, Grace Maline

Theses/Capstones/Creative Projects

Inflammatory Bowel Diseases (IBD) including ulcerative colitis, indeterminate colitis, and Crohn’s disease are increasingly common conditions that places a high physical and financial burden on individuals and global healthcare systems. Though many treatments exist for these conditions, their unpredictable nature and causation make them difficult to manage across the variety of IBD patients. Additionally, many of these treatments come with undesirable side effects or modes of delivery. Therefore, it is worthwhile to explore the use of Short Chain Fatty Acids (SCFAs) such as butyrate whose affects in the human gut include decreased inflammation and decreased risk of colorectal cancer. As …
