Implementation Of An Opioid Risk Assessment Tool, Stacey Cuomo Dec 2017

Implementation Of An Opioid Risk Assessment Tool, Stacey Cuomo

Seton Hall University DNP Final Projects

The increased prevalence of opioid use in society has led to an increase in surgical patients with a history of such use. Patients who use or are addicted to opioids have different tolerances and responses to anesthesia than non-opioid users, and will require different care than non-users both pre- and post-operatively. The means to identify this population prior to a surgical procedure is needed as a way to organize, plan and manage patient care during the perioperative period. An Opioid Risk Assessment Tool (ORAT) was used as a way to streamline the process of identifying these patients. This paper addresses …

Inflammatory bowel diseases (IBD) are likely driven by aberrant immune responses directed against the resident microbiota. Although IBD is commonly associated with a dysbiotic microbiota enriched in putative pathobionts, the etiological agents of IBD remain unknown. Using a pathobiont-induced intestinal inflammation model and a defined bacterial community, we provide new insights into the immune-microbiota interactions during disease. In this model system, the pathobiont Helicobacter bilis instigates disease following sub-pathological dextran sulfate sodium treatment. We show that H. bilis causes mild inflammation in mono-associated mice, but severe disease in the presence of a microbiota, demonstrating synergy between the pathobiont and microbiota …


Using Social Narratives To Improve The Healthcare Experiences Of Children Diagnosed With Autism Spectrum Disorder, Margaret Spindel Dec 2017

Using Social Narratives To Improve The Healthcare Experiences Of Children Diagnosed With Autism Spectrum Disorder, Margaret Spindel

Senior Honors Projects, 2010-2019

Children with Autism Spectrum Disorder (ASD) often experience significant emotional stress when they visit a healthcare provider. The focus of this research project was to explore the use of social narratives to help reduce stress associated with this environment. Social narratives are short stories designed to walk a child through a potential situation that they will encounter, that they may not be familiar with, or that they are not currently handling properly. As part of an initial literature review, evidence for the need for additional intervention in the healthcare setting for children with ASD was established. Continuing literature review then …

Next Generation Sequencing Technologies For Real-Time Genotyping And Targeted Sequencing For Precision Medicine, Priyanka Rawat

Biomedical Engineering ETDs

Astounding success of Human genome project and accelerating success of sequencing technologies have enabled $ 1000 genome goals possible. But, this is still far-fetched from the reach of many resource refrained populations with high genetic variations causing lethal genetic diseases. Based on present technology principles, I have developed prototypes for affordable, scalable and customizable point-of-care genotyping and targeted sequencing. Ion-sensitive field effect transistors with novel read-out and signal amplification techniques are used for laying foundation of possible ISFET based allele-arrays. Sequencing-by-synthesis based full-fledge sequencer is made with novel immobilization, flow-cell and data acquisition methods for massive sequenciing.

To investigate how to optimize care transitions, qualitative descriptive information was collected through three personal interviews to gain a broader understanding of mechanisms of care transitions in London, ON. After conducting interviews and literature review, the CARED Tool was developed. The CARED Tool promotes social inclusion of patients with dementia through recognizing that people with dementia have complex needs, thereby allowing …


Subanesthetic Ketamine For Postoperative Analgesia: An Evidenced-Based Project, Jeremy Vance Dec 2017

Subanesthetic Ketamine For Postoperative Analgesia: An Evidenced-Based Project, Jeremy Vance

Doctoral Projects

Roughly 100 million surgical procedures are performed in the United States (U.S.) each year and more than 80% of these patients experience acute postoperative pain. Pain costs the U.S. an estimated $560 to $635 billion annually and is a significant contributor to national rates of mortality, morbidity, and disability. Despite these findings, patients continue to receive suboptimal postoperative pain relief.

The adjunct administration of subanesthetic ketamine is opioid-sparing and can improve the effectiveness of a multimodal pain management approach. This project used an exploratory descriptive design to examine how an evidence-based presentation impacted the clinical practice of certified registered nurse …

The Correlation Of Size Of Core Network And Frequency Of Contacts With Agitation And Positive Affect In Elderly With Dementia, Amal Ali Al Ghassani Dec 2017

The Correlation Of Size Of Core Network And Frequency Of Contacts With Agitation And Positive Affect In Elderly With Dementia, Amal Ali Al Ghassani

Theses and Dissertations

In the country of Oman, care needs of older adults are primarily provided by family members in the home. The study was guided by socioemotional selectivity theory, the environmental vulnerability hypothesis, and the need-driven dementia-compromised behavior theories. The central premise was that the size of the person’s activities of daily living (ADL) core network and frequency of contact with the ADL core network would predict agitation and affect. A smaller core network with a higher frequency of contact may be better at identifying and treating the person’s unmet needs. A secondary premise was that the emotional closeness of the core …

Weight-Loss Treatment-Induced Physical Activity Associated With Improved Nutrition Through Changes In Social Cognitive Theory Variables In Women With Obesity, James J. Annesi, Nicole Mareno

Health Behavior Research

Behavioral weight-loss treatments have typically been unsuccessful and a theoretical. Even when treatments were scientifically derived, theory has rarely been used to decompose, and understand the bases of, their effects. This 2-year study evaluated mediation of the prediction of nutritional changes by changes in physical activity, through social cognitive theory variables. Data from women with Class 1–2 obesity, classified as “insufficiently active” (N = 50; Mage = 47.6 years), were extracted from 2 initial trials of a new cognitive-behavioral intervention. That treatment sought to improve self-regulation, mood, and self-efficacy through increased physical activity, to then induce improved eating …


Managing The Cost Of Diabetes, Laressa Bethishou Oct 2017

Managing The Cost Of Diabetes, Laressa Bethishou

Pharmacy Faculty Articles and Research

"This is of concern to health care providers because inadequate management of diabetes results in short- and long-term complications. Patients with diabetes and no health insurance have fewer physician visits and are prescribed fewer medications for management of their diabetes. Patients with diabetes make up 11.9% of all emergency department visits in the United States.Hispanic and non-Hispanic blacks are at greater risk for developing diabetes and serious associated health complications, including chronic kidney disease. This may be attributed to a combination of genetics, diet, and exercise. However, access to health care resources may also play an important role."

The impoverished organ donors are treated in an inhumane manner, as they are often left with serious medical complications and are not treated equally in the transaction.


Yawns Are Cool, Andrew C. Gallup, Omar T. Eldakar Sep 2017

Yawns Are Cool, Andrew C. Gallup, Omar T. Eldakar

Biology Faculty Articles

Although we yawn each and every day, most people have little understanding of why we do it. In fact, the function of yawning has remained mysterious for centuries, even among scientists, and this has only changed quite recently. Contrary to what people have believed for a long time, it is now understood that yawns have nothing to do with breathing or the amount of oxygen we are taking in. Instead, new and growing research has revealed that yawns serve as a brain cooling mechanism. This new perspective on yawning as a response to elevated brain temperature has transformed our understanding …

The Roles Of Ecdysoneless In Endoplasmic Reticulum Stress And Oncogenesis, Appolinaire A. Olou Aug 2017

The Roles Of Ecdysoneless In Endoplasmic Reticulum Stress And Oncogenesis, Appolinaire A. Olou

Theses & Dissertations

Tumor cells are well known to exhibit ER stress as a result of their altered environment characterized by redox and calcium imbalance, deregulation of protein synthesis to meet their oncogenic demands, and decreased vascularization associated with nutrient limitation and hypoxia, all of which are conducive of ER stress. Accordingly, markers of ER stress signaling response are up-regulated in various cancers. The outcome of ER stress signaling response varies from survival and adaption to apoptosis. Although pro-apoptotic ER stress signaling molecules are up-regulated in cancer, the mechanisms by which cancer cells seem refractory to, or evade, their apoptotic signaling are not …

Pharmacy Faculty Articles and Research

Traceable poly(ethylene oxide)-poly(ester) micelles were developed through chemical conjugation of a near-infrared (NIR) dye to the poly(ester) end by click chemistry. This strategy was tried for micelles with poly(ε-caprolactone) (PCL) or poly(α-benzyl carboxylate-ε-caprolactone) (PBCL) cores. The surface of both micelles was also modified with the breast cancer targeting peptide, P18-4. The results showed the positive contribution of PBCL over PCL core on micellar thermodynamic and kinetic stability as well as accumulation in primary orthotopic MDA-MB-231 tumors within 4–96 h following intravenous administration in mice. This was in contrast to in vitro studies where better uptake of PEO-PCL versus PEO-PBCL micelles …
