Cag Repeat Length And Suicidality In Huntington's Disease, Christen Kutz

Health Sciences Program Student Theses, Dissertations and Capstones

Abstract: The purpose of this study was to determine if a correlation exists between suicide and CAG repeat length in Huntington’s disease. Methodology: A case-control study using the COHORT Study de-identified database was conducted. Responses were collected from 163 participants. Depression, substance abuse history and use of benzodiazepines were covariates. Responses to the UHDRS behavioral section pertaining to the frequency and severity of suicidal ideation (“feels life is not worth living”, “has suicidal thoughts”) were analyzed. Results: Despite taking depression, benzodiazepine use, and history of substance abuse into account, there was a predictive relationship between CAG repeat length and frequency …

Nursing Students' Perceived Value Of The Pre-Briefing Phase Of Simulation, Jill Renae Chamberlain

Student Theses, Dissertations and Capstones

As technology has grown, many healthcare professions’ programs, including nursing, have incorporated simulation into their curricula. Overwhelmingly, research has highlighted the last phase of simulation, debriefing, as the most important component influencing learning outcomes, with limited focus on prebriefing. The purpose of this study was to describe the influence the prebriefing phase during simulation has on undergraduate nursing students’ perceptions of overall simulation effectiveness, learning, and self-confidence. Situated learning theory was selected to guide the research design due to its unique view that learning is a social process that is enhanced within the authentic environment. The quasi-experimental design study compared …

Age Related Decline In Memory: Examining The Mediation Effect Of Processing, Executive Functioning And Intelligence In Normal Adults, Jada J. Stewart

Theses and Dissertations

Multiple mediation analyses that collectively examine the prominent theories of cognitive aging (i.e., Common Cause, Processing, and Executive Decline Hypotheses) along with other cognitive domains that are sensitive to aging are rare. Moreover, having identified that cognition begins to decline as early as 30 years old, few studies have examined the mechanisms that underlie memory change among younger aging individuals. As a result, it is unclear whether relevant mediating variables have been excluded from early research on age-related memory decline, or to what extent rehabilitative strategies are applicable as early interventions for maintaining cognitive functioning into late life.

Achieving Competence: Clinical Instructors' Perspective, Kimberly W. Coleman-Ferreira

Department of Physical Therapy Student Theses, Dissertations and Capstones

Purpose: The profession of physical therapy uses physical therapist clinical instructors to educate students in the clinical education portion of the curriculum. The requirements to become a clinical instructor are minimal and non- specific regarding formal training and development. A variety of educational opportunities is available to clinical instructors, but the evidence in the physical therapy literature is conflicting regarding the effectiveness of these programs. Additionally, no previous research regarding the meaning of competence, nor the pathway to achieving competence as a clinical instructor was found. Therefore, the purpose of this study was to describe the experience of achieving competence …

Family Therapist Connecting And Building Relationships With Substance Abusers In The Seminole Tribe Of Florida: An Ethnographic Study, Sunny Nelli Khachatryan

Department of Family Therapy Dissertations and Applied Clinical Projects

The purpose of this ethnographic study was to examine the process of a family therapist entering and then navigating the cultural system of working with substance abusing Seminole tribal clients. The study also utilized two tribal members sharing their opinions about how Seminoles view therapy. As noted in the interview questions and responses, the research presented guidelines for family therapists to follow when working with tribal members. Because there has been no study conducted with family therapists providing clinical services to tribal members, this study introduced tools for clinicians to keep in mind and utilize when working with tribal clients. …

The Lived Experiences Of Adult Children Of Mid To Later-Life Parental Divorce: An Interpretative Phenomenological Analysis, Joan Collins Ricketts

Department of Family Therapy Dissertations and Applied Clinical Projects

This study examined the lived experiences of adult children of mid-later life parental divorce. It was designed and conducted to address the gap in the current literature regarding this phenomenon. The experiences of 5 Adult Children of Divorce (ACD) ages 25 to 45, who experienced mid-later life parental divorce, were examined using in-depth semi-structured interviews. The researcher employed an interpretive phenomenological analysis (IPA) of which the findings illustrated various outcomes for adults experiencing their parents’ mid-later life divorce. The results of this study showed that parents’ waiting until the children are “grown” does not mitigate potentially detrimental outcomes for these …

Faculty Publications

Two students with autism, vision impairment, and intellectual disability participated in an orientation and mobility (O&M) intervention to travel in school settings using their folding canes. A multiple-baseline across participants design to determine the effectiveness of the intervention was used. The dependent variable was time taken to travel the specified route. The independent variable was O&M training. Results indicated that both participants took less time to travel during the intervention compared to the baseline. Students with vision impairment and autism can be trained using systematic O&M training. The O&M specialists working with children with autism and vision impairment should collect …

Brief Consultation To Families Of Treatment Refusers With Symptoms Of Obsessive Compulsive Disorder: Does It Impact Family Accommodation And Quality Of Life?, Melanie M. Vandyke, C. Alec Pollard, Jacob Harper, Kyle E. Conlon

Faculty Publications

Family members are often directly and significantly impacted by the restrictive demands of OCD, a frequently disabling disorder. Family accommodation behaviors (i.e., doing things for or because of the OCD sufferer that a person would not normally do) are associated with dysfunction, including poorer treatment responses in OCD sufferers and greater distress in family members. Although evidence suggests family-based intervention can reduce symptoms in OCD sufferers who participate in treatment, there is a lack of research documenting the impact of interventions designed for the families of OCD treatment refusers (TR). Brief Family Consultation (BFC) was developed by our clinical team …

Experiences With Weight Loss Triggers In Women Prescribed To Lose Weight By Their Physician, Mark D. Faries, Elizabeth Espie, Erik Gnagy, Kyle P. Mcmorries

Faculty Publications

Background: With the global rise of individuals classified as overweight and obese, weight-related screenings have been promoted to combat their high prevalence and associated health problems. Hopefully, such screenings can act as a ‘trigger’ for health behavior change, however little is known about the experience of weight loss triggers.
Objectives: The aim of this study was to elaborate on the experiences and meanings of weight-control triggers in a sample of overweight women prescribed by their physician to lose weight.
Patients and Methods: We conducted exploratory qualitative interviews, grounded in phenomenological practices, to elaborate on the experience and meaning of weight …

The Relationship Of Female Physical Attractiveness To Body Fatness, Guanlin Wang, Kurosh Djafarian, Chima A. Egedigwe, Asmaa El Hamdouchi, Robert Ojiambo, Harris Ramuth, Sandra Johanna Wallner-Liebmann, Sonja Lackner, Adama Diouf, Justina Sauciuvenaite, Catherine Hambly, Lobke M. Vaanholt, Mark D. Faries, John R. Speakman

Faculty Publications

Aspects of the female body may be attractive because they signal evolutionary fitness. Greater body fatness might reflect greater potential to survive famines, but individuals carrying larger fat stores may have poor health and lower fertility in non-famine conditions. A mathematical statistical model using epidemiological data linking fatness to fitness traits, predicted a peaked relationship between fatness and attractiveness (maximum at body mass index (BMI) = 22.8 to 24.8 depending on ethnicity and assumptions). Participants from three Caucasian populations (Austria, Lithuania and the UK), three Asian populations (China, Iran and Mauritius) and four African populations (Kenya, Morocco, Nigeria and Senegal) …

Enabling Real-Time Ultrasound Imaging Of Soft Tissue Mechanical Properties By Simplification Of The Shear Wave Motion Equation, Aaron J. Engel, Gregory R. Bashford

Biomedical Imaging and Biosignal Analysis Laboratory

Ultrasound based shear wave elastography (SWE) is a technique used for non-invasive characterization and imaging of soft tissue mechanical properties. Robust estimation of shear wave propagation speed is essential for imaging of soft tissue mechanical properties. In this study we propose to estimate shear wave speed by inversion of the firstorder wave equation following directional filtering. This approach relies on estimation of first-order derivatives which allows for accurate estimations using smaller smoothing filters than when estimating second-order derivatives. The performance was compared to three current methods used to estimate shear wave propagation speed: direct inversion of the wave equation (DIWE), …

Symptom Perceptions And Self-Care Behaviors In Patients Who Self-Manage Heart Failure, Katherine M. Reeder, Patrick M. Ercole, Gina M. Peek, Carol E. Smith

College of Nursing Faculty Publications

Background: Patients with heart failure (HF) are at heightened risk for acute exacerbation requiring hospitalization. Although timely reporting of symptoms can expedite outpatient treatment and avoid the need for hospitalization, few patients recognize and respond to symptoms until acutely ill.

Objective: The purpose of this study was to explore patients’ perceptions of symptoms and self-care behaviors for symptom relief, leading up to a HF hospitalization.

Methods: To examine prehospitalization symptom scenarios, semistructured interviews were conducted with 60 patients hospitalized for acute decompensated HF.

Results: Thirty-seven patients (61.7%) said that they had a sense that “something just wasn’t quite right” before …

The Predictive Value Of The Proliferation Marker Ki-67 In Patients With Fulminant Hepatic Failure, Ashesh P. Shah, Md, Upasana Joneja, Md, David Walls, Md, John Farber, Md

Department of Pathology, Anatomy, and Cell Biology Resident's Posters

INTRODUCTION

In the United States, acute liver failure (ALF) affects an estimated 2,000 people per year and accounts for 6% of all liver transplants. Without transplantation, however, less than 50% of patients survive with medical management alone. Early identification of patients with survivable AFL is important to guiding their management and early referral to transplantation.

Studies have shown that the current prognostic scoring systems used for FHF, including the King’s College Criteria (KCC) and the Model for End- Stage Liver Disease (MELD), have poor sensitivity and negative predictive value for predicting outcome, highlighting a need for more accurate predictive models. …

Do Emergency Department Patients Receive A Pathological Diagnosis? A Nationally-Representative Sample, Leana Wen, Janice A. Espinola, Joshua M. Mosowsky, Carlos A. Camargo

Emergency Medicine Faculty Publications

Introduction: Understanding the cause of patients’ symptoms often requires identifying a pathological diagnosis. A single-center study found that many patients discharged from the emergency department (ED) do not receive a pathological diagnosis. We analyzed 17 years of data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) to identify the proportion of patients who received a pathological diagnosis at ED discharge. We hypothesized that many patients do not receive a pathological diagnosis, and that the proportion of pathological diagnoses increased between 1993 and 2009.

Methods:Using the NHAMCS data from 1993-2009, we analyzed visits of patients age ≥18 years, …

Just Compensation: A No-Fault Proposal For Research-Related Injuries, Leslie Meltzer Henry, Megan E. Larkin, Elizabeth R. Pike

Faculty Scholarship

Biomedical research, no matter how well designed and ethically conducted, carries uncertainties and exposes participants to risk of injury. Research injuries can range from the relatively minor to those that result in hospitalization, permanent disability, or even death. Participants might also suffer a range of economic harms related to their injuries. Unlike the vast majority of developed countries, which have implemented no-fault compensation systems, the United States continues to rely on the tort system to compensate injured research participants—an approach that is no longer morally defensible. Despite decades of US advisory panels advocating for no-fault compensation, little progress has been …

Respect And Dignity: A Conceptual Model For Patients In The Intensive Care Unit, Leslie Meltzer Henry, Cynda Rushton, Mary Catherine Beach, Ruth Faden

Faculty Scholarship

Although the concept of dignity is commonly invoked in clinical care, there is not widespread agreement—in either the academic literature or in everyday clinical conversations—about what dignity means. Without a framework for understanding dignity, it is difficult to determine what threatens patients’ dignity and, conversely, how to honor commitments to protect and promote it. This article aims to change that by offering the first conceptual model of dignity for patients in the intensive care unit. The conceptual model we present is based on the notion that there are three sources of patients’ dignity—their shared humanity, personal narratives, and autonomy—each of …

Effect Of Single Embryo Transfer On The Risk Of Preterm Birth Associated With In Vitro Fertilization, A. J. Fechner, K. R. Brown, N. Onwubalili, S. K. Jindal, G. Weiss, L. T. Goldsmith, P. G. Mcgovern

Journal Articles

To determine whether elective single embryo transfer (eSET) reduces the risk of preterm delivery associated with in vitro fertilization (IVF). This is an observational study of 3125 eSET cycles performed from 2008 to 2009 and reported to the Society for Assisted Reproductive Technology (SART) database. Preterm delivery rates were compared to the overall preterm delivery rate among all patients undergoing IVF over the same time period. The 3125 eSET cycles resulted in 1507 live births (live birth rate 48.2 %) Among these deliveries were 27 twins (1.8 %) and one set of triplets (0.07 %). The overall preterm delivery rate …

Metabolic Resting-State Brain Networks In Health And Disease, P. G. Spetsieris, J. H. Ko, C. C. Tang, A. Nazem, W. Sako, S. Peng, Y. Ma, V. Dhawan, D. Eidelberg

Journal Articles

The delineation of resting state networks (RSNs) in the human brain relies on the analysis of temporal fluctuations in functional MRI signal, representing a small fraction of total neuronal activity. Here, we used metabolic PET, which maps nonfluctuating signals related to total activity, to identify and validate reproducible RSN topographies in healthy and disease populations. In healthy subjects, the dominant (first component) metabolic RSN was topographically similar to the default mode network (DMN). In contrast, in Parkinson's disease (PD), this RSN was subordinated to an independent disease-related pattern. Network functionality was assessed by quantifying metabolic RSN expression in cerebral blood …

Implications Of Epigenetic Variability Within A Cell Population For "Cell Type" Classification, I. Tabansky, J. N.H. Stern, D. W. Pfaff

Journal Articles

Here, we propose a new approach to defining nerve "cell types" in reaction to recent advances in single cell analysis. Among cells previously thought to be equivalent, considerable differences in global gene expression and biased tendencies among differing developmental fates have been demonstrated within multiple lineages. The model of classifying cells into distinct types thus has to be revised to account for this intrinsic variability. A "cell type" could be a group of cells that possess similar, but not necessarily identical properties, variable within a spectrum of epigenetic adjustments that permit its developmental path toward a specific function to be …

Parkinson's Disease-Related Spatial Covariance Pattern Identified With Resting-State Functional Mri, T. Wu, Y. Ma, Z. Zheng, S. Peng, X. Wu, D. Eidelberg, P. Chan

Journal Articles

In this study, we sought to identify a disease-related spatial covariance pattern of spontaneous neural activity in Parkinson's disease using resting-state functional magnetic resonance imaging (MRI). Time-series data were acquired in 58 patients with early to moderate stage Parkinson's disease and 54 healthy controls, and analyzed by Scaled Subprofile Model Principal Component Analysis toolbox. A split-sample analysis was also performed in a derivation sample of 28 patients and 28 control subjects and validated in a prospective testing sample of 30 patients and 26 control subjects. The topographic pattern of neural activity in Parkinson's disease was characterized by decreased activity in …

First-In-Human, Phase 1, Randomized, Dose-Escalation Trial With Recombinant Anti-Il-20 Monoclonal Antibody In Patients With Psoriasis, A. B. Gottlieb, J. G. Krueger, M. Sandberg Lundblad, M. Gothberg, B. E. Skolnick

Journal Articles

BACKGROUND: The current trial was a first-in-human clinical trial evaluating the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy of the recombinant monoclonal anti-interleukin-20 (IL-20) antibody, NNC0109-0012, which targets the inflammatory cytokine IL-20. METHODS: In total, 48 patients aged 18 to 75 years with moderate to severe stable chronic plaque psoriasis with affected body surface area >/=15% and physician global assessment score >/=3 were enrolled in this randomized, double-blind, multicenter, placebo-controlled, phase 1 dose-escalation trial. Patients were randomized within each single dose cohort (0.01, 0.05, 0.2, 0.6, 1.5, or 3.0 mg/kg) or multiple dose cohort (0.05, 0.2, 0.5, 1.0, or 2.0 …

Mesothelioma Patients With Germline Bap1 Mutations Have 7-Fold Improved Long-Term Survival, F. Baumann, E. Flores, A. Napolitano, S. Kanodia, E. Taioli, H. Pass, H. Yang, M. Carbone

Journal Articles

BRCA1-associated protein-1 (BAP1) mutations cause a new cancer syndrome, with a high rate of malignant mesothelioma (MM). Here, we tested the hypothesis that MM associated with germline BAP1 mutations has a better prognosis compared with sporadic MM. We compared survival among germline BAP1 mutation MM patients with that of all MM (N = 10 556) recorded in the United States Surveillance, Epidemiology, and End Results (SEER) data from 1973 to 2010. We identified 23 MM patients-11 alive-with germline BAP1 mutations and available data on survival. Ten patients had peritoneal MM, ten pleural MM and three MM in both locations. Thirteen …

The Glass Is Half Full: Evidence For Efficacy Of Alcohol-Wise At One University But Not The Other, K. Croom, L. Staiano-Coico, M. Lesser, D. K. Lewis, V. F. Reyna, T. C. Marchell, J. Frank, S. Ives

Journal Articles

This research extends the growing literature about online alcohol prevention programs for first-year college students. Two independent randomized control studies, conducted at separate universities, evaluated the short-term effectiveness of Alcohol-Wise, an online alcohol prevention program not previously studied. It was hypothesized the prevention program would increase alcohol knowledge and reduce alcohol consumption, including high-risk alcohol-related behaviors, among first-year college students. At both universities, the intervention significantly increased alcohol-related knowledge. At one university, the prevention program also significantly reduced alcohol consumption and high-risk drinking behaviors, such as playing drinking games, heavy drinking, and extreme ritualistic alcohol consumption. Implications for the use …

Journal Articles

BACKGROUND: Adipokines and inflammation may provide a mechanistic link between obesity and postmenopausal breast cancer, yet epidemiologic data on their associations with breast cancer risk are limited. METHODS: In a case-cohort analysis nested within the Women's Health Initiative Observational Study, a prospective cohort of postmenopausal women, baseline plasma samples from 875 incident breast cancer case patients and 839 subcohort participants were tested for levels of seven adipokines, namely leptin, adiponectin, resistin, interleukin-6, tumor necrosis factor-alpha, hepatocyte growth factor, and plasminogen activator inhibitor-1, and for C-reactive protein (CRP), an inflammatory marker. Data were analyzed by multivariable Cox modeling that included established …
