Genome-Scale Precision Proteomics Identifies Cancer Signaling Networks And Therapeutic Vulnerabilities, Hong Wang

Theses and Dissertations (ETD)

Mass spectrometry (MS) based-proteomics technology has been emerging as an indispensable tool for biomedical research. But the highly diverse physical and chemical properties of the protein building blocks and the dramatic human proteome complexity largely limited proteomic profiling depth. Moreover, there was a lack of high-throughput quantitative strategies that were both precise and parallel to in-depth proteomic techniques. To solve these grand challenges, a high resolution liquid chromatography (LC) system that coupled with an advanced mass spectrometer was developed to allow genome-scale human proteome identification. Using the combination of pre-MS peptide fractionation, MS2-based interference detection and post-MS computational interference correction, …

Statistical Methods For Assessing Structural Change In Human & Microbial Genomes, Xuan Zhu

Dissertations and Theses (Open Access)

Genetic sequencing has been recognized as an effective approach to accurately address biological problems, such as clinical detection of disease, mutation discovery, and targeting specific biomarkers associated with complex diseases. Compared with conventional Sanger sequencing, next-generation sequencing costs much less due to massively parallel high-throughput sequencing. However, due to large numbers of short read sequences, the accuracy of high-throughput sequencing data remains a challenge in that the data obtained from next-generation sequencing often has higher error rates, which may impact downstream genomic analysis. Even if the downstream genomic analysis performs well, the quality of the result will still be impacted …

Ultrasound Monitoring Of Extant Adnexal Masses In The Era Of Type 1 And Type 2 Ovarian Cancers: Lessons Learned From Ovarian Cancer Screening Trials, Eleanor L. Ormsby, Edward J. Pavlik, John P. Mcgahan

Obstetrics and Gynecology Faculty Publications

Women that are positive for an ovarian abnormality in a clinical setting can have either a malignancy or a benign tumor with probability favoring the benign alternative. Accelerating the abnormality to surgery will result in a high number of unnecessary procedures that will place cost burdens on the individual and the health delivery system. Surveillance using serial ultrasonography is a reasonable alternative that can be used to discover if changes in the ovarian abnormality will occur that favor either a malignant or benign interpretation. Several ovarian cancer screening trials have had extensive experiences with changes in subclinical ovarian abnormalities in …

Mallampati Scoring And Its Relation To Obstructive Sleep Apnea, Austin Korczak

Honors Capstones

According to the American Sleep Apnea Association potentially 80% of moderate to severe cases of Obstructive Sleep Apnea (OSA) go undiagnosed with even optimistic estimates stating that at least 22 million Americans are afflicted by the disorder. These numbers are expected to continue to increase due to the rising rates of obesity in America. As a result, reliable criteria that can help physicians accurately predict the presence of an underlying sleep disorder, whose symptoms are masked during the day, is highly sought after. The objective of this research is to begin defining these criteria via a literature review of articles …

A Review Of Ankylosing Spondylitis, Hannah L. Owen

Senior Honors Theses

Ankylosing spondylitis (AS) is a systemic autoimmune disorder that induces ankylosis of the spine (fusion of the vertebrae at their various joints) and inflammatory arthritis of peripheral joints among other symptoms. Overexpression of cytokines, the presence of genetic mutations not exclusive to the human leucocyte antigen (HLA)-B27 region, and environmental factors all have large roles in the progressive development of AS. Although a definitive pathology continues to be sought after, researchers believe the adaptive immune system in AS patients attacks fibrocartilaginous entheses (supportive connective tissue between bone and attached structures like tendon, ligament, and fascia).

AS markedly reduces proper systemic …

Examination Of Neurocorrelates Of Mild Traumatic Brain Injury In Young Adults, Rachel J. Raucci

Neuroscience Honors Papers

In recent years, there has been an upswing in the number of concussion diagnoses per year in the United States, particularly in young athletes with still-developing brains. Accompanying this recent trend is an increased amount of research on concussions and their long-term impacts. This ongoing research project collects and compares data from concussed and non-concussed individuals using various neuropsychological batteries, self-report surveys and participants’ EEG readings. Data analysis of the results from 51 participants indicates that previously concussed individuals differ from their non-concussed counterparts. Specifically, individuals who have suffered a concussion exhibit specific and occasionally idiosyncratic deficits in executive control …

Proper Prescribing Of Controlled Drugs: A Pilot Study Of A Web-Based Learning Modules’ Impact On Knowledge, Attitude, And Practice In New Graduate Nurse Practitioners, Shelly Duckett

DNP Projects

Controlled substance abuse is a global epidemic. Several factors that influence health care providers prescribing habits have been presented in recent literature. However, the existing evidence primarily reflects the prescribing habits of physicians, while relatively little is known about the prescribing habits of nurse practitioners. The purpose of this project is to evaluate the impact of a brief web-based continuing education module targeting appropriate prescribing of controlled substances for recent graduate nurse practitioners. The project served to assess the provider’s knowledge, attitude, and practice compared to current integrated curriculum on prescribing and assess change in knowledge. Two online educational modules …

Effects Of Therapeutic Music On Pain In Spinal Surgery Recovery, Michael Poulsen

Evidence-Based Practice Project Reports

Pain is one of the most common experienced symptoms reported by more than 80% of postoperative patients. Approximately 77-98% of postoperative patients report pain following their procedure with 40- 80% having moderate to severe pain. Pain is shown to elevate stress levels manifesting in increased heart rates, blood pressures, and oxygen demand. Inadequate pain control can develop into surgical complications causing surgical failure, blood clots, pneumonia, and chronic pain. Complimentary and alternative medicine such as music can be used in combination with opioid medication help improve pain control leading to successful surgical outcomes. The purpose of this evidence-based practice project …

High School Student Concussion Recovery Program: Teacher Involvement In Student Academic Transitions To Classroom And To Sports, Brittany Diego

Scholarly and Creative Works Conference (2015 - 2021)

Many symptoms of concussions can greatly interfere with the cognitive abilities and skills students use in school. Although students may have similar symptoms, they experience concussions differently. Students returning to the classroom from a concussion often have different needs and abilities.

Research shows that a formal, individualized protocol to treat suspected concussions, both academically and physically, is vital to the successful recovery of each student. Much research is available on concussions for professional athletes, specifically related to recovery and returning to their sport. However, there is little research about high school students regarding concussions. Concussion recovery programs for high school …

Ten Important Considerations For Ovarian Cancer Screening, Edward J. Pavlik

Obstetrics and Gynecology Faculty Publications

The unique intricacies of ovarian cancer screening and perspectives of different screening methods are presented as ten considerations that are examined. Included in these considerations are: (1) Deciding on the number of individuals to be screened; (2) Anticipating screening group reductions due to death; (3) Deciding on the duration and frequency of screening; (4) Deciding on an appropriate follow-up period after screening; (5) Deciding on time to surgery when malignancy is suspected; (6) Deciding on how screen-detected ovarian cancers are treated and by whom; (7) Deciding on how to treat the data of enrolled participants; (8) Deciding on the most …

Evaluation Of Circulating Mirnas During Late Pregnancy In The Mare, Shavahn C. Loux, Kirsten E. Scoggin, Jason E. Bruemmer, Igor F. Canisso, Mats H. T. Troedsson, Edward L. Squires, Barry A. Ball

Veterinary Science Faculty Publications

MicroRNAs (miRNAs) are small, non-coding RNAs which are produced throughout the body. Individual tissues tend to have a specific expression profile and excrete many of these miRNAs into circulation. These circulating miRNAs may be diagnostically valuable biomarkers for assessing the presence of disease while minimizing invasive testing. In women, numerous circulating miRNAs have been identified which change significantly during pregnancy-related complications (e.g. chorioamnionitis, eclampsia, recurrent pregnancy loss); however, no prior work has been done in this area in the horse. To identify pregnancy-specific miRNAs, we collected serial whole blood samples in pregnant mares at 8, 9, 10 m of gestation …

Head Out Of Water Weighing: A Valid Method To Measure Body Fat Storage?, Molly Hussey

Annual Graduate Student Symposium

Underwater weighing with full lung expiration has been established as a valid method to assess body composition. Many people do not prefer this method due to various reasons. Hydrostatic weighing with head above water at full lung capacity has been tested although not accepted as an alternative method. Purpose: The main purpose of this study is to examine if hydrostatic weighing with the head above water could be a better method to measure body composition. Methods: Fifty-nine subjects (F=29, M=30) participated in performing four different methods of underwater weighing: complete immersion at full lung expiration (UWWRV) and total lung capacity …

Toward A Research Agenda For Oncology Physical Therapy, Lucinda Pfalzer, Nicole L. Stout, Shana Harrington, Mary Insana Fisher

Physical Therapy Faculty Publications

Research Round-up: Cancer survivors frequently experience cancer treatment–related functional impairments and disability. While a growing body of evidence supports the effectiveness of rehabilitation interventions for these individuals, there are significant gaps in the existing literature and no interdisciplinary agreement on the priorities for cancer rehabilitation research. In 2016, the Oncology Section revised its strategic plan and set an objective to create an oncology rehabilitation research agenda for the physical therapy (PT) profession. To achieve this goal, the scope of the agenda, a development and review process, and dissemination plan need to be developed.

Emergency Department Approach To Electrical Toothbrush Associated Hand Injury, A Unique Case Of Non-Oropharyngeal Injury., Hannah Robinson, Neal Sikka, Chimere Little, Ali Pourmand

GW Research Days 2016 - 2020

Puncture wounds are common injuries treated in the emergency department (ED). Prior studies have shown that toothbrushes are common reservoirs for oral flora, especially in regions near the head of the toothbrush near the bristles. ED providers must be aware of the danger associated with bacterial contamination of the associated wound and should be familiar with different pathogens and options for treatment. We present a unique case of a 30-year-old male with non-intraoral injury who presented to the ED after puncturing his left palm with the metal post of an electric toothbrush.

Concussion Screening Evaluation: Bess Vs Sway, Zachariah Hatoum, Aidan Neustadtl, Jeremy Altman, Aurash Zarrinbakhsh, David Milzman

GW Research Days 2016 - 2020

Introduction: Rapid evaluation of concussion is important in the pre-hospital setting as an easy test. It is also useful in the ED, as too often little is done for concussed patients. The Balance Error Scoring System (BESS) is the current gold standard for evaluating balance, one of the best predictors of concussion. SWAY, a new gyroscope based iPhone application, is being proposed as a more sensitive and more objective test than BESS. This study will compare Sway to BESS to determine if there is equal efficacy.
Method: 74 scholastic and collegiate athletes were administered baseline balance evaluations using Sway. …

Nephrotoxicity In Patients With Or Without Cystic Fibrosis Treated With Polymyxin B Compared To Colistin, Ryan L. Crass, Wilbur Cliff Rutter, Donna R. Burgess, Craig A. Martin, David S. Burgess

Pharmacy Practice and Science Faculty Publications

Nephrotoxicity is the primary adverse effect of the polymyxins. The relative rates of toxicity of polymyxin B and colistin have not been fully elucidated, especially in patients with cystic fibrosis (CF). A retrospective cohort study of adults treated with polymyxin B or colistin for at least 48 h was conducted. The primary endpoint was the incidence of kidney injury assessed by RIFLE (i.e., risk, injury, failure, loss, end-stage renal disease) criteria. Risk factors for kidney injury were evaluated using multivariate Cox regression. A total of 414 patients were evaluated, 220 of whom had CF. In patients without CF, there was …

The objective of this study was to determine the relationship between step frequency, the Running Readiness Scale, and Running-Related Injury rate among the Otterbein cross-country team during the Fall 2016 season. Step frequencies were calculated for each athlete at a preferred and pre-determined pace. As a part of the running Readiness Scale assessment, each athlete completed a series of screening tasks to assess body alignment, weight distribution, and muscular endurance. Each participant logged their running and injury history throughout the season using the Otterbein Run Tracker app. The researchers hypothesized that higher step frequencies and Running Readiness Scale pass rates …

Ovarian Cancer Incidence Corrected For Oophorectomy, Lauren A. Baldwin, Quan Chen, Thomas C. Tucker, Connie G. White, Robert N. Ore, Bin Huang

Obstetrics and Gynecology Faculty Publications

Current reported incidence rates for ovarian cancer may significantly underestimate the true rate because of the inclusion of women in the calculations who are not at risk for ovarian cancer due to prior benign salpingo-oophorectomy (SO). We have considered prior SO to more realistically estimate risk for ovarian cancer. Kentucky Health Claims Data, International Classification of Disease 9 (ICD-9) codes, Current Procedure Terminology (CPT) codes, and Kentucky Behavioral Risk Factor Surveillance System (BRFSS) Data were used to identify women who have undergone SO in Kentucky, and these women were removed from the at-risk pool in order to re-assess incidence rates …

Genomic Contraindications For Heart Transplantation., Danton S. Char, Gabriel Lázaro-Muñoz, Aliessa Barnes, David Magnus, Michael J. Deem, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

Genome sequencing raises new ethical challenges. Decoding the genome produces new forms of diagnostic and prognostic information; however, the information is often difficult to interpret. The connection between most genetic variants and their phenotypic manifestations is not understood. This scenario is particularly true for disorders that are not associated with an autosomal genetic variant. The analytic uncertainty is compounded by moral uncertainty about how, exactly, the results of genomic testing should influence clinical decisions. In this Ethics Rounds, we present a case in which genomic findings seemed to play a role in deciding whether a patient was to be listed …

Increasing Ed Use Of Jet Injection Of Lidocaine For Iv-Related Pain Management., Shobhit Jain, Mary A. Hegenbarth, Sharon Humiston, Erin Gunter, Lynn Anson, Joan Giovanni

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND AND OBJECTIVE: Venipuncture is a leading cause of procedural pain for children. Jet injection of lidocaine (JIL; J-Tip) has been demonstrated to be effective in controlling intravenous (IV) placement-related pain and, due to its rapid onset, is particularly suited to emergency department (ED) use. Our objective was to increase JIL use with IV placements in our ED from 11% at baseline to 50% within 12 months.

METHODS: We initiated the project at our urban, tertiary pediatric ED in July 2014. We surveyed medical and nursing teams to identify barriers to JIL use. We initiated changes at monthly intervals: (1) …

Npy1 Receptor Agonist Modulates Development Of Depressive-Like Behavior And Gene Expression In Hypothalamus In Sps Rodent Ptsd Model, Lidia Serova, H Mulhall, Esther Sabban

NYMC Faculty Publications

Delivery of neuropeptide Y (NPY) to the brain by intranasal infusion soon after traumatic stress has shown therapeutic potential, and prevented development of many behavioral and neuroendocrine impairments in the single prolonged stress (SPS) animal model of PTSD. Therefore, we examined whether the Y1R preferring agonist [Leu(31)Pro(34)]NPY is sufficient to prevent development of SPS induced depressive-like behavioral changes, and hypothalamic gene expression as obtained with intranasal NPY intervention. Male Sprague-Dawely rats were given intranasal infusion of either NPY (150 mug/rat), a low (68 mug /rat), or high (132 mug/rat) dose of [Leu(31)Pro(34)]NPY or vehicle immediately following the last SPS stressor, …
