A Comparison Of Spatio-Temporal Prediction Methods Of Cancer Incidence In The U.S, Michelle Hamlyn

UNLV Theses, Dissertations, Professional Papers, and Capstones

Cancer is the cause of one out of four deaths in the United States, and in 2009, researchers expected over 1.5 million new patients to be diagnosed with some form of cancer. People diagnosed with cancer, whether a common or rare type, need to undergo treatments, the amount and kind of which will depend on the severity of the cancer. So how do healthcare providers know how much funding is needed for treatment? What would better enable a pharmaceutical company to determine how much to allocate for research and development of drugs, the amount of each drug to manufacture, or …

Applying Inventory Control Practices Within The Sisters Of Mercy Health Care Supply Chain, Server Apras

Graduate Theses and Dissertations

This research lays a foundation for the better understanding of the application and acceptance of more advanced inventory control practices within the health care supply chain. The demand characteristics and optimal control policies for pharmaceutical items within a multi-echelon provider network are examined within the framework of a case study. Demand forecasting algorithms were applied to forecast demand for inventory control procedures. A spreadsheet-based inventory planning tool was used to minimize the inventory holding and ordering costs subject to fill rate constraints. The costs of inventory control models are compared to the current ordering and inventory control strategies to document …

Faculty’S Perceptions Of Students’ Abilities To Utilize Self-Regulated Learning Strategies To Improve Critical And Reflective Thinking In Making Clinical Decisions: A Methodological Study, Amber Lynn Donnelli

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the rapidly changing health care system, new nurses are expected to be able to collect pertinent data, access resources, prioritize information, solve problems, and ultimately make sound clinical decisions (Kuiper, 2005). Supporting evidence has shown that using self-regulated learning strategies (SRLS) increases the development of critical and reflective thinking within the clinical reasoning context (Kuiper & Pesut, 2004). Despite the fact that instruments have been developed to examine students’ perception of the use of SRLS, there is no existing instrument to measure nursing faculty’s perceptions of a student’s ability to utilize self-regulated learning strategies in the clinical setting. This …

Fresh perspectives in these areas are opened up by examining the ways that research and application …

Synergistic Combination Of Hyperoxygenation And Radiotherapy By Repeated Assessments Of Tumor Po2 With Epr Oximetry, Huagang Hou, Ruhong Dong, Jean P. Lariviere, Sriram P. Mupparaju, Harold M. Swartz, Nadeem Khan

Dartmouth Scholarship

The effect of hyperoxygenation with carbogen (95% O₂ + 5% CO₂) inhalation on RIF-1 tumor pO₂and its consequence on growth inhibition with fractionated radiotherapy is reported. The temporal changes in the tumor pO₂ were assessed by in vivo Electron Paramagnetic Resonance (EPR) oximetry in mice breathing 30% O₂ or carbogen and the tumors were irradiated with 4 Gy/day for 5 consecutive days; a protocol that emulates the clinical application of carbogen. The RIF-1 tumors were hypoxic with a tissue pO₂ of 5–9 mmHg. Carbogen (CB) breathing significantly increased tumor pO₂, …

Classification And Treatment Of Proximal Humerus Fractures: Inter-Observer Reliability And Agreement Across Imaging Modalities And Experience., Abtin Foroohar, Rick Tosti, John M Richmond, John P Gaughan, Asif M Ilyas

Rothman Institute Papers

SUMMARY: Proximal humerus fractures (PHF) are common injuries, but previous studies have documented poor inter-observer reliability in fracture classification. This disparity has been attributed to multiple variables including poor imaging studies and inadequate surgeon experience. The purpose of this study is to evaluate whether inter-observer agreement can be improved with the application of multiple imaging modalities including X-ray, CT, and 3D CT reconstructions, stratified by physician experience, for both classification and treatment of PHFs.

METHODS: Inter-observer agreement was measured for classification and treatment of PHFs. A total of sixteen fractures were imaged by plain X-ray (scapular AP and lateral), CT …

Protection And Attachment Of Vibrio Cholerae Mediated By The Toxin-Coregulated Pilus In The Infant Mouse Model, Shelly J. Krebs, Ronald K. Taylor

Dartmouth Scholarship

Colonization of the human small intestine by Vibrio cholerae is an essential step in pathogenesis that requires the type IV toxin-coregulated pilus (TCP). To date, three functions of TCP have been characterized: it serves as the CTXΦ receptor, secretes the colonization factor TcpF, and functions in microcolony formation by mediating bacterium-bacterium interactions. Although type IV pili in other pathogenic bacteria have been characterized as playing a major role in attachment to epithelial cells, there are very few studies to suggest that TCP acts as an attachment factor. Taking this into consideration, we investigated the function of TCP in attachment to …

Creation Of Multilinage Adult Stem-Like Cells From Terminally Differentiatied Fibroblasts, John Moore

Theses and Dissertations

Induced Pluripotent Stem cells (iPScs) are artificially generated cells that demonstrate multilineage differentiation potential. These cells demonstrate similar morphology and high differentiation potential to Embryonic Stem Cells (ESCs). Generation of these cells from a terminally differentiated cell line requires activation of the core pluripotency genes Nanog, Oct4, and Sox2 as well as an oncogenic stimulus such as c-Myc. Here we examine the effect of the Human Pappiloma Virus derived proteins E6 and E7 on the ability of a terminally differentiated fibroblast cell line to a more primitive state and examine its multilineage differentiation capacity. In this paper, we attempt to …

Functional Characterization Of The Streptococcus Sanguinis Com Regulon, Jill Callahan

Theses and Dissertations

Streptococcus sanguinis is an important component of the dental plaque biofilm and is believed to play a beneficial role in the oral cavity. S. sanguinis is also a leading cause of infective endocarditis (IE), a potentially lethal infection of the cardiac valves. S. sanguinis possesses genetic competence, the ability to acquire exogenous DNA into its genome. In the well characterized system of S. pneumoniae, genetic competence requires a quorum sensing system encoded by the early comCDE genes, as well as late genes controlled by the alternate sigma factor, ComX. Previous studies in other streptococcal species have suggested functions for the …

How Many Steps/Day Are Enough? For Children And Adolescents, Catrine Tudor-Locke, Cora L. Craig, Michael W. Beets, Sarahjane Belton, Greet M. Cardon, Scott Duncan, Yoshiro Hatano, David R. Lubans, Timothy S. Olds, Anders Raustorp, David A. Rowe, John C. Spence, Shigeho Tanaka, Steven N. Blair

Worldwide, public health physical activity guidelines include special emphasis on populations of children (typically 6-11 years) and adolescents (typically 12-19 years). Existing guidelines are commonly expressed in terms of frequency, time, and intensity of behaviour. However, the simple step output from both accelerometers and pedometers is gaining increased credibility in research and practice as a reasonable approximation of daily ambulatory physical activity volume. Therefore, the purpose of this article is to review existing child and adolescent objectively monitored step-defined physical activity literature to provide researchers, practitioners, and lay people who use accelerometers and pedometers with evidence-based translations of these public …

How Many Steps/Day Are Enough? For Adults, Catrine Tudor-Locke, Cora L. Craig, Wendy J. Brown, Stacy A. Clemes, Katrien Decocker, Billie Giles-Corti, Yoshiro Hatano, Shigeru Inoue, Sandra M. Matsudo, Nanette Mutrie, Jean-Michel Oppert, David A. Rowe, Michael D. Schmidt, Grant M. Schofield, John C. Spence, Pedro J. Teixeira, Mark A. Tully, Steven N. Blair

Faculty Publications

Physical activity guidelines from around the world are typically expressed in terms of frequency, duration, and intensity parameters. Objective monitoring using pedometers and accelerometers offers a new opportunity to measure and communicate physical activity in terms of steps/day. Various step-based versions and translations of physical activity guidelines are emerging, reflecting public interest in such guidance. However, there appears to be a wide discrepancy in the exact values that are being communicated. It makes sense that step-based recommendations should be harmonious with existing evidence-based public health guidelines that recognized that "some physical activity is better than none" while maintaining a focus …

How Many Steps/Day Are Enough? For Older Adults And Special Populations, Catrine Tudor-Locke, Cora L. Craig, Yukitoshi Aoyagi, Rhonda C. Bell, Karen A.

Older adults and special populations (living with disability and/or chronic illness that may limit mobility and/or physical endurance) can benefit from practicing a more physically active lifestyle, typically by increasing ambulatory activity. Step counting devices (accelerometers and pedometers) offer an opportunity to monitor daily ambulatory activity; however, an appropriate translation of public health guidelines in terms of steps/day is unknown. Therefore this review was conducted to translate public health recommendations in terms of steps/day. Normative data indicates that 1) healthy older adults average 2,000-9,000 steps/day, and 2) special populations average 1,200-8,800 steps/day. Pedometer-based interventions in older adults and special populations …

Effectiveness Of A Combined Home Visiting And Group Intervention For Low Income African American Mothers: The Pride In Parenting Program, Kathy S. Katz, Marian H. Jarrett, Ayman El-Mohandes, Susan Schneider, Doris Mcneely-Johnson, Michele Kiely

Publications and Research

Intervention strategies are needed to improve maternal and infant outcomes in minority populations living in poverty. Home visiting by nurses has improved outcomes for mothers and young children, but use of professional staff makes these programs expensive. Pride in Parenting was a randomized controlled trial of paraprofessional home visitation to provide health and developmental intervention for high-risk African American mothers in Washington, DC. This study proposed to test whether paraprofessional visitors drawn from the community could effectively influence health and mothers; parenting behaviors and attitudes. African American mothers with inadequate prenatal care were recruited at delivery and randomized to intervention …

The Levels Of Analysis Revisited., Scott A Macdougall-Shackleton

Brain and Mind Institute Researchers' Publications

The term levels of analysis has been used in several ways: to distinguish between ultimate and proximate levels, to categorize different kinds of research questions and to differentiate levels of reductionism. Because questions regarding ultimate function and proximate mechanisms are logically distinct, I suggest that distinguishing between these two levels is the best use of the term. Integrating across levels in research has potential risks, but many benefits. Consideration at one level can help generate novel hypotheses at the other, define categories of behaviour and set criteria that must be addressed. Taking an adaptationist stance thus strengthens research on proximate …

A Review Of Common And Rare Genetic Variants In Schizophrenia, Jonathan Luedders

Theses and Dissertations

Genetic epidemiology has shown a large role for genetic influences on schizophrenia. However, the nature of the variants involved is debated. The common disease-common variant (CDCV) hypothesis suggests that schizophrenia is caused by common alleles with small effect sizes. According to the common disease-rare variant (CDRV) hypothesis, schizophrenia is caused by rare variants with large effect sizes. In recent years, evidence has been found for both common and rare variants in schizophrenia. Several SNPs have been associated with schizophrenia through genome-wide association studies (GWAS), supporting the CDCV hypothesis. In support of the CDRV hypothesis, individuals with schizophrenia have been found …

Network Modulation During Complex Syntactic Processing, Dirk B. Den Ouden, Dorothee Saur, Wolfgang Mader, Björn Schelter, Sladjana Lukic, Eisha Wali, Jens Timmer, Cynthia K. Thompson

Communication Sciences and Disorders Faculty Articles and Research

Complex sentence processing is supported by a left-lateralized neural network including inferior frontal cortex and posterior superior temporal cortex. This study investigates the pattern of connectivity and information flow within this network. We used fMRI BOLD data derived from 12 healthy participants reported in an earlier study (Thompson, C. K., Den Ouden, D. B., Bonakdarpour, B., Garibaldi, K., & Parrish, T. B. (2010b). Neural plasticity and treatment-induced recovery of sentence processing in agrammatism. Neuropsychologia, 48(11), 3211–3227) to identify activation peaks associated with object-cleft over syntactically less complex subject-cleft processing. Directed Partial Correlation Analysis was conducted on time series …

A Comparative Study Of A Pathogenic Versus A Nonpathogenic Naegleria Species, Melissa Jamerson

Theses and Dissertations

Naegleria fowleri (N. fowleri) and Naegleria lovaniensis (N. lovaniensis) are closely related amebae found in the environment. N. fowleri causes Primary Amebic Meningoencephalitis (PAM), a fatal disease of the central nervous system, while N. lovaniensis is nonpathogenic. N. fowleri infection occurs when amebae enter the nasal passages, and migrate to the brain. The molecular mechanisms involved in the pathogenesis of PAM are not well-defined. Therefore, the purpose of this study was to define phenotypic characteristics that may be functionally linked to the pathogenicity associated with N. fowleri. Studies revealed that N. fowleri has a faster growth rate and is more …

Therapeutic Guitar-An Alternative Approach To The Treatment Of A Difficult Patient, Michael Buxbaum, Md

Jefferson Journal of Psychiatry

The case described in this article is one where an experimental technique was introduced largely because of the therapist's dissatisfaction with the patient's progress. Despite the likelihood of being criticized, I feel compelled to write about this patient. The progress he has made is beyond my expectations, which were admittedly minimal at the outset.

Misuses Of Computers By Adolescents, Henry A. Doenlen, M.D.

Jefferson Journal of Psychiatry

One subject that has been a topic of much recent publicity and concern has been that of computer misuse. Teenage computer programmers gaining entry into the systems of universities, hospitals and businesses have caused the most concern . The duplication of copyrighted programs and information has also been reported to cause loss of considerable money. There seems to be a subpopulation of people who spend considerable time working with computers. These individuals may do so to the exclusion of other aspects of life such as human interaction . This paper will present both my observations of this behavior and my …

The Treatment Of A Borderline Patient Complicated By Involvement With A Charismatic Religious Cult: A Case Report, Mark Miller, Md

Jefferson Journal of Psychiatry

Introduction

Although much has been written about cults in recent years, many questions remain. Do cults recruit subjects by brainw ashing them or do individuals gravitate to cults to fulfill unmet needs? This paper will review some essential points of cult phenomena and discuss the treatment of one patient who was involved in a charismatic religious cult .

Possible Synergistic Action Between Carbamazepine And Lithium Carbonate In The Treatment Of A Manic Patient., John Matt Dorn, M.D.

Jefferson Journal of Psychiatry

Introduction

Carbamazepine has been proven to be efficacious in some patients with affective disorders, notably those who have not responded well to lithium carbonate or neuroleptics (1,2,3) . For those who have responded poorly to either regimen, however, there have been no effective pharmacotherapies until recently, when case reports have suggested a possible synergistic action between lithium carbonate and carbamazepine (4,5,6). The following case report supports this hypothesis.

The Use Of Carbamazepine (Tegretol) In Psychiatry And Its Association To Kindling, Temporal Lobe Epilepsy And Psychopathology, James Stanch, M.D.

Jefferson Journal of Psychiatry

The recent theory of kindling may help to link neurophysiologic, neurotransmitter and neuroanatomic mechanisms important in understanding the neurology of behavior. Limbic kindling is of interest in developing models of epilepsy, psychosis, learning and memory (l -5). Kindling might explain the late development of psychopathology.

This paper will first define kindling and demonstrate how kindling offers a model within which to view more prolonged behavioral deviations as neurophysiological processes. The use of carbamazepine and its association to kindling, temporal lobe dysfunction and psychopathology will be discussed .

Discussion Of The Paper By David A. Scola, M.D. On “The Hemispheric Specialization Of The Human Brain And Its Application To Psychoanalytic Principles”, Howard Field, M.D., Paul J. Fink, M.D., Thomas Swirsky-Sacchetti, Ph.D.

Jefferson Journal of Psychiatry

Dr. Scola proposes a bold and far-reaching synthesis of psychoanalytic theory, developmental neurobiology and neurophysiology of behavior. Freud found this task so frustrating in 1895 that he renounced neurology in favor of a purely psychologic approach (or so Freud claimed; Frank Sulloway sees it differently). Hypotheses that unconscious mental life is situated in the right cerebrum and that defense mechanisms are related to neuroanatomic connections are intriguing. The presentation does not include evidence which contravenes these theories. Sperry presented some evidence that the right hemisphere is self-aware and self-evaluative (I). One great problem in all cross disciplinary studies is the …

The Hemispheric Specialization Of The Human Brain And Its Application To Psychoanalytic Principles, David A. Scola, M.D.

Jefferson Journal of Psychiatry

Volumes of research have been accumulated over the past decade concerning hemispheric specialization of the human brain. Likewise, over the past century, psychoanalysts have painstakingly unraveled through their clinical observation many of the mysteries of intrapsychic functions. Yet little has been written concerning attempts to integrate these seemingly divergent viewpoints.

It was Freud's hope that a neural basis for his clinical observations and psychological explanations of the human mind would eventually be established . This was not possible in his day, however, so this idea was gradually abandoned. With the advent of computers and high technology, perhaps it is time …
