Chemical Restraints In The Emergency Department, Nicholas Noffsinger

Rowan-Virtua Research Day

Chemical restraint is a critical intervention used in emergency departments to manage acutely agitated or violent patients. It involves the administration of medication to induce sedation and control behavior, with the goal of ensuring patient and staff safety while allowing necessary medical interventions to be performed. However, the use of chemical restraints necessitates close observation of vital signs and any potential side effects, as well as careful consideration of patient-specific considerations.

Brief Review: Iv Fluid Choice In The Emergency Department, Kaywan Saed, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Normal saline and balanced crystalloids, such as lactated Ringer's (LR) and Plasma-Lyte A, are commonly used in the emergency setting for fluid resuscitation. However, there has been growing interest in recent years in whether balanced crystalloids may be superior to normal saline, particularly in critically ill patients.

Normal saline has been the traditional fluid of choice for decades due to its widespread availability, low cost, and presumed safety. However, normal saline has a high chloride concentration (154 mmol/L), which can lead to hyperchloremic metabolic acidosis and other adverse effects, such as renal vasoconstriction and reduced renal blood flow.

In contrast, …

Comparative Analysis Of The Effects Of Actual Versus Assumed Opioid Experience On The Regulation Of Ventral Striatal Opioid Receptor Gene Expression, Indu Mithra Madhuranthakam, Martin Job

Rowan-Virtua Research Day

Rationale: We conducted experiments to assess the effect of prior opioid experience on gene expression changes. We compared the current experimenter-imposed short versus extended-access conditions of opioid self-administration and developed a new quantitative method to determine their effectiveness in identifying the role of opioid experience in regulating opioid receptor expression levels in the ventral striatum (VS) using an oxycodone self-administration/abstinence model.

Methods: In this study, male Sprague-Dawley rats (n=36) were trained for 20 days to self-administer oxycodone at 0.1 mg/kg/infusion under short access (n=15, or saline as controls n=3, for 3h/day) or extended access (n=15, or saline as controls n=3, …

Correlation Between Gut Biomarkers And Depression, Jianle Gao

Rowan-Virtua Research Day

The correlation between the gut-microbiota- brain axis and mental state in the context of mental disorders such as Major Depressive Disorder (MDD), Schizophrenia, etc. has been well studied. Production of inflammatory and non-inflammatory metabolites by the gut- microbiota directly and indirectly affects the brain and mood. Therefore, colonization by maladaptive, pro-inflammatory bacteria may cause mood dysregulation and depressive features. Metabolites from these bacteria can be quantitatively analyzed for use as biomarkers of Major Depressive Disorder. Biomarkers studied include: serotonin, dopamine, butyrate, acetate, and propionate.

Brief Review: Patient Pill Splitting. What Is The Appropriate Advice To Provide Patients In The Emergency Department?, Mohammad Rattu, James Espinosa, Gabriel Meister, Alan Lucerna

Rowan-Virtua Research Day

A number of patients have inquired about the practice of pill splitting. Cutting or splitting of pills can be used by patients to create an intermediate dose or to save on money where a higher dose is priced at relatively the same cost as a lower dose. In this review we discuss a number of issues related to medication safety and table splitting.

Growing Use Of Xylazine As An Adulterant In Opioids And Its Effects, Oluwapelumi Oluwo

Rowan-Virtua Research Day

Xylazine, according to the National Institutes of Health (NIH), is a non-opioid tranquilizer used in veterinary medicine. Although this drug has not been approved for human use, it can be linked to an increase in opioid overdose deaths due to its role as an adulterant in drugs like fentanyl.

Xylazine was detected in drugs involved in 41% of all opioid-involved unintentional deaths and in 44% of all unintentional overdose deaths with fentanyl involved in the year of 2021 in Philadelphia.

Management And Considerations In The Usage Of Txa In Hemorrhagic Trauma Patients, Matthew Petterson, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Tranexamic acid is a synthetic reversible competitive inhibitor that exerts its action on plasminogen, preventing plasmin formation and deterring fibrinolysis.1 Current FDA-approved indications of TXA include heavy menstrual bleeding and short-term blood loss prevention in patients with hemophilia following tooth extraction.1 TXA has more recently been utilized in the management of massive hemorrhagic trauma patients despite this being an off-label use. While TXA has shown promise as a hemostatic agent for this patient population, considerations in the pre-hospital and hospital settings must be examined for its integration into massive hemorrhage protocols.

Case Report And Review: Promethazine ("Purple Drank") Abuse, Riya Tandra, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

A 23 year old female was brought to the Emergency Department by EMS for confusion and aggressive behavior. The friends told EMS that the patient had been ingesting "purple drank" and that she had told her friends that she made the concoction with promethazine and opiate cough syrup with some vodka added. She mixed it in a carbonated soda. “Purple Drank” or “Lean” is a combination of codeine promethazine hydrochloride and soda or alcohol that has frequently been misused since the 1990s. This paper aims to highlight the recent resurgence of promethazine abuse occurring in the United States as well …

Release The Kratom: Post-Acute Withdrawal Syndrome In A 70 Year Old Male, Nardin El-Shammaa, Kyle Street, Narshima Pinninti

Rowan-Virtua Research Day

Centuries in Eastern medicine.. Kratom has been commonly used for chronic pain and opiate withdrawal symptoms with first reported cases in the United States in the early 2000s. It is a plant that consists of psychoactive alkaloids that target opioid receptors with different affinity. Effects from Kratom are dose-dependent, at lower doses, it acts as a stimulant, while at higher doses produces analgesia and euphoria. Although Kratom is legal and easily accessible over the counter, there have been increasing reports of potential for addiction and toxicity. Cessation of Kratom can result in withdrawal symptoms similar to opiate withdrawal. Here we …

Role Of Gper In Cadmium-Induced Phosphorylation Of Erk1/2 In Ovarian Adenocarcinoma, Laura Sackie

Undergraduate Theses

Cadmium, a carcinogenic heavy metal, is an environmental contaminant found in air, water, and soil. It also exhibits endocrine disruptive properties by mimicking the proliferative effects of the hormone estrogen and is classified as a metalloestrogen. At low concentration levels in some cancer cells, cadmium induces cell proliferation and phosphorylation of ERK1/2, a key protein in the estrogen signaling pathway. While the signaling pathways for cadmium- induced phosphorylation of ERK1/2 have been discovered in breast and lung cancer cells, it has not yet been fully determined in ovarian cancer cells. The fairly recent discovery of a transmembrane receptor found in …

Photodynamic Therapy Agents: The Power Of Mjöllnir To Eradicate Cancer, Sidney M. Hopper

Honors College Theses

After its discovery back in the 1900s, photosensitizers became a critical study for potential treatments and cures for medical issues, including cancer. It was discovered that porphyrins appeared to target and accumulate in proliferating cells, and to reach the cells, a certain wavelength of light with maximum absorbance associated with the porphyrin was necessary to achieve cell death. Photodynamic therapy involves making use of porphyrins or metalloporphyrins as activators when exposed to such light. When activated, these compounds generate reactive oxygen species (ROS), such as HO- or O2-, which can react with nucleic acids found in DNA and RNA. In …

Utilizing Ultra-Performance Chromatography High-Resolution Mass Spectrometry To Investigate Fatty Acid Mediated Antibiotic Tolerance, Brittni Woodall

Doctoral Dissertations

The lipid membrane is the first component necessary to sustain life. To maintain homeostasis, segregate cellular machinery, provide protection from the environment, and reproduce, an organism must establish a boundary in which the processes can occur. Throughout the last two decades, research has propelled our knowledge of lipid membranes much beyond original hypotheses. Once thought of to be static and uniform, the understanding of the lipid membrane has evolved to encompass a structure that is responsive, unique, and intricately constructed by the organism itself. By chance or by choice, organisms adapt the lipid membrane according to the environment for which …

Nicotinamide Riboside And Beta-Hydroxybutyrate Activate Parallel Pathways For C. Elegans Lifespan Extension, Mckenzie Peters

Undergraduate Honors Theses

Supplementation with nicotinamide riboside (NR), a form of vitamin B3 and a precursor of nicotinamide adenine dinucleotide (NAD⁺) extends lifespan in the nematode C. elegans and delays aging-related pathologies in mammals. During aging, levels of NAD⁺ decline causing metabolic dysfunction and oxidative damage. Studies in C. elegans found that when NR was administered during larval development it induced the mitochondrial unfolded protein response (UPR^mt), which is frequently associated with lifespan extension. Both calorie restriction (CR) and ketogenic diets (KD) have been shown to extend lifespan, in part through increasing NAD⁺ and through increasing levels …

Cytotoxic Effects Of Bpa And Dehp On Human Epithelial Cells, Noah Stickrod

Theses/Capstones/Creative Projects

Endocrine disrupting chemicals (EDCs) are substances in the environment, food sources, personal care products, and manufactured products that interfere with the normal function of the body’s endocrine system. Most humans are exposed to some amount of these chemicals from many different sources, such as the air we breathe, food we eat, and the water we drink. EDCs can also permeate through the skin. The endocrine system is important because it works with other systems in the body to ensure healthy development and function throughout life. EDCs interfere with the way our body’s hormones work. Some EDCs can mimic natural hormones …

Uncovering Molecular Targets To Overcome Immunosuppression In Non-Small Cell Lung Cancer With Acquired Tki Resistance, Sonia A. Patel

Dissertations & Theses (Open Access)

Non-small cell lung cancer (NSCLC) remains the leading cause of cancer-related deaths worldwide. Targeted therapeutic agents, such as epidermal-like growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) or monoclonal antibodies targeting vascular endothelial growth factor (VEGF/R), can effectively inhibit upregulated signaling pathways driving tumorigenesis in NSCLC and many other cancers. Unfortunately, however, resistance to such targeted therapies inevitably arise in most patients and can occur through a variety of resistance mechanisms including genomic alterations and upregulation of bypass pathways. Additionally, patients who have acquired resistance to these targeted agents typically have tumors characterized by an immunosuppressive tumor microenvironment and thus …

Forensic Science Master's Projects

For decades, cannabis consumption has remained one of the most controversial topics of discussion in both science and law. However, Cannabis sativa, from which both hemp and marijuana are derived, has served as an essential component of medicine, industry, and recreation for centuries. Approximately 500 compounds have been identified from cannabis alone, and only around 66 are termed cannabinoids which account for the majority of research on the substance. The major cannabinoid constituents include delta 9-tetrahydrocannabinol (delta 9-THC), responsible for the psychoactive effects of cannabis, in addition to, cannabidiol (CBD), tetrahydrocannbinolic acid (THCA), cannbidolic acid (CBDA), cannbigerol (CBG), …

Study On The Effect Of Lipoic Acid Presence In Heptamethine Cyanine Dyes For Near-Infrared Surface-Enhanced Raman Scattering (Nir-Sers), George Pollinger

Forensic Science Master's Projects

The use of Near-Infrared (NIR) Surface-Enhanced Raman Spectroscopy (SERS) has recently served as a strong candidate for highly sensitive bioimaging without the use of ionizing radiation and strong magnetic fields. Given the potential of heptamethine cyanine dyes to absorb in the NIR region while retaining stability and sensitivity, recent research has focused on altering the chemical moiety at the heptamethine displacing the meso-chloride to discover novel reporter molecules with enhanced SERS signaling. Such research has determined that lipoic acidcontaining N-acetyl amino tri-carbocyanine can produce a strong SERS intensity, given the affinity of sulfur for AuNPs. Such discoveries have utilized improper …
