Alzheimer’s disease (AD) is a degenerative brain disease caused by β Amyloid plaques and neurofibrillary tangles, which results in memory loss and cognitive decline. It is the sixth leading cause of death in the United States. Approximately 50% of those with AD experience some degree of depression during the course of the disease, which has been shown to accelerate functional decline, institutionalization, and even mortality.

Many who cannot care for themselves live in an assisted living facility or retirement home. Since the beginning of the COVID 19 pandemic, people have been urged to social distance in order to decrease the …

An Unusual Ed Case: Aortic Aneurysm Presenting As Chf Exacerbation, Darren Finn, James Espinosa, Russell Mordecai, Kishan Patel

Rowan-Virtua Research Day

There has been a significant increase in the incidence of thoracic aortic aneurysms, currently making aneurysmal disease the 18th most common cause of death within the United States. This disease is typically an insidious one, with the aorta growing an average of only 0.1 cm per year. Consequently, most patients remain asymptomatic until late stages of the disease when dissection or worse, rupture has occurred. Under extremely rare circumstances, thoracic aortic aneurysms can present clinically due to mass effect. Airway, esophageal and vascular compression, secondary to aortic arch dilation has been previously documented. The condition can be acquired or congenital, …

Brachial Artery Aneurysm After Arteriovenous Fistula Ligation Status Post-Kidney Transplant, Alyssa Imperatore, Justin Adibi, Rahul Sharma, Yury Bak

Rowan-Virtua Research Day

Arteriovenous fistulas (AVF) are the most common and effective method of receiving hemodialysis; However, these access techniques do not come without consequence. Aneurysmal degeneration after creation and even years after ligation of such AVF can occur. This is still considered a rare complication. A true brachial artery aneurysm has an overall incidence of 0.17% among peripheral artery aneurysms. Factors that increase incidence of this complication include trauma, age and immunosuppression. Research on this topic is becoming more prevalent, but more answers are still needed. Below is a case of brachial artery aneurysm presenting years after AVF ligation in a patient …

Case Presentation: Lower Back Pain Or Chronic Acetaminophen Overdose?, Meghan Whitt, Christopher Schwartz, Bhumi Shah

Rowan-Virtua Research Day

Unintentional ingestions can pose a difficult challenge to diagnose in the setting of the Emergency Department. Many may present with vague symptoms that are not consistent with classic overdose prodromes. Many patients do not identify or disclose over the counter medications, such as analgesics, with which acute/chronic ingestion in large quantities can result in life threatening medical emergencies. Their underlying symptoms may also cloud their clinical picture, further complicating workup within the ED.

Rowan-Virtua Research Day

Spinal Epidural Lipomatosis (SEL) an excess of normal adipose tissue in the epidural space of the spinal canal, typically becoming symptomatic when cord compression results. First described in 1975 by Lee et al (Lee M, 1975), it is a relatively rare disease. Unfortunately, it is often diagnosed once patients have developed marked symptoms and can have dire complications. Oftentimes SEL is completely asymptomatic, and symptoms on initial presentation are vague. Mostly commonly it presents as worsening chronic back pain (Daniel R. Fassett M.D. M.B.A., 2004) with progressive lower extremity weakness and occasional cauda equina syndrome (Wells AJ, 2014), but this …

Case Study Of Pulmonary Embolism With Unusual Chief Complaint, Kajel Patel

Rowan-Virtua Research Day

Pulmonary embolism (PE) is a serious diagnosis that needs to be made in the Emergency department (ED). There are different categories of PE ranging from massive to non-massive/sub-segmental. Regardless of the categorization, the patient will need to be placed on anticoagulation. It is important to catch this diagnosis in the ED so further complications do no arise. Here is a case from the ED with a patient coming in with the chief complaint of acute right lower quadrant abdominal pain and was diagnosed with a pulmonary embolism.


Ethnic Differences In Maternal Cytokines And Adipokines And Their Association With Spontaneous Preterm Delivery, Yelizavet D. Lomakova, Xinhua Chen May 2021

Ethnic Differences In Maternal Cytokines And Adipokines And Their Association With Spontaneous Preterm Delivery, Yelizavet D. Lomakova, Xinhua Chen

Rowan-Virtua Research Day

Spontaneous preterm delivery (SPTD, birth at <37 weeks’ gestation) is a leading cause of infant mortality in the United States [1]. Infants born prematurely are more likely to suffer from both short and long-term complications including neurodevelopmental delay, visual and hearing impairment, and chronic diseases such as heart disease, hypertension and diabetes in later life [2-4]. African American women have a 2-fold increased risk of preterm delivery compared to Caucasian women [5].The reasons for this disparity are poorly understood. This limits the ability to predict and prevent preterm delivery in the most high-risk populations.

Multiple Myeloma With Dual Expression Of Kappa And Lambda Light Chains, Monica Patel, Akash Patel, Yvette Wang

Rowan-Virtua Research Day

Multiple myeloma (MM) is a malignancy of plasma cells that accounts for approximately 1 to 2 percent of all cancers and about 17% of all hematologic malignancies.

Plasma cells normally produce antibodies and provide a defense mechanism for the body to fight infections.

Antibodies typically consist of two heavy chains (IgG, IgA, IgM, IgD and IgE) and two light chains (kappa and lambda).

Most cases of MM have malignant plasma cells producing monoclonal (M) proteins, most common being IgG about 52% of the time (1).

Only about 2% of these myeloma cases were also found to secrete more than one …

Omental infarction is a rare cause of acute abdomen pain first described by Eitel in 1899 and has been described in the literature with total numbers ranging from 250-400 worldwide with many coming from individual case reports. Risk factors for developing omental infarction are thought to be obesity, trauma, intense exercise or secondary to torsion from adhesions. Historically, the diagnosis of omental infarction was made incidentally in the operating room for patients with an acute abdomen with a different suspected diagnosis. Most often being appendicitis with associated right lower quadrant abdominal pain and smaller subset from suspected diverticulitis and cholecystitis …


Long-Term Impacts Of Acute Stressor Exposure On Locus Coeruleus Function And Anxiety-Like Behavior In Rats, Olga Borodovitsyna Apr 2021

Long-Term Impacts Of Acute Stressor Exposure On Locus Coeruleus Function And Anxiety-Like Behavior In Rats, Olga Borodovitsyna

Graduate School of Biomedical Sciences Theses and Dissertations

Stress is a physiological state characterized by behavioral arousal that occurs during exposure to harmful or threatening stimuli, and usually facilitates an adaptive behavioral response. The persistence of stress sometimes causes it to become maladaptive, potentially contributing to disease development, including physiological complications with altered neuroendocrine signaling and impaired function of organ systems, and psychological conditions including depression and anxiety. Anxiety disorders in particular are associated with a history of stress and are the most common class of mental disorders, with a lifetime prevalence of 33.7% in the general population. The locus coeruleus (LC) is a major node in the …

Abstract

Acupuncture is an complementary form of medicine that has relatively recently become a component of traditional Chinese medicine (TCM). It involves the application of thin needles at specific points throughout the body, although initially, general areas instead of points were used. There are estimated to be about 395 different points that can be utilized, and the technique behind using these points can vary widely between practitioners. In addition to acupuncture points, TCM is said to use meridians or pathways along with qi, or energy flows. In terms of acupunctures’ utility, it has been known to treat a variety of …

Effect Of S100b Deletion On Membrane Properties And Localization Of Ncald And Hpca, Natasha Hesketh

Graduate School of Biomedical Sciences Theses and Dissertations

Calcium signaling is particularly important for neuronal function. Neurons utilize a wide range of calcium-binding proteins. Dysregulation of such proteins is linked to neurodegeneration. Neurocalcin delta (NCALD), hippocalcin (HPCA), and S100B are calcium sensors that are expressed in the hippocampus, a brain region essential to memory and severely damaged in Alzheimer’s disease (AD). Despite the potential importance of these proteins, we do not fully understand the physiological significance of their relationship. Because NCALD and HPCA are known to interact with S100B, we hypothesized that the loss of S100B affects NCALD and HPCA localization, and therefore electrical properties, of hippocampal neurons. …

Myelin and lymphocyte protein (MAL) is a tetraspan integral membrane protein that resides in detergent-insoluble membrane fractions enriched in condensed membranes. MAL is expressed in oligodendrocytes, in Schwann cells, where it is essential for the stability of myelin, and at the apical membrane of epithelial cells, where it has a critical role in transport. In T lymphocytes, MAL is found at the immunological synapse and plays a crucial role in exosome secretion. However, no involvement of MAL in viral infections has been reported so far. Here, we show that herpes simplex virus 1 (HSV-1) virions travel in association with MAL-positive …
