Malmberg, A.M. Carlsson, P.E. Ferreira, M.G. Petzold, D. Blessborn, Y. Bergqvist, J.P. Gil, Zul Premji, A. Martensson

Pathology, East Africa

Background: Home-management of malaria (HMM) strategy improves early access of anti-malarial medicines to high-risk groups in remote areas of sub-Saharan Africa. However, limited data are available on the effectiveness of using artemisinin-based combination therapy (ACT) within the HMM strategy. The aim of this study was to assess the effectiveness of artemether-lumefantrine (AL), presently the most favoured ACT in Africa, in under-five children with uncomplicated Plasmodium falciparum malaria in Tanzania, when provided by community health workers (CHWs) and administered unsupervised by parents or guardians at home.

Methods: An open label, single arm prospective study was conducted in two rural villages …

Community Screening And Treatment Of Asymptomatic Carriers Of Plasmodium Falciparum With Artemether-Lumefantrine To Reduce Malaria Disease Burden: A Modelling And Simulation Analysis, S.E. Kern, A.B. Tiono, M. Makanga, A. Gbadoe, Zul Premji, O. Gaye, I. Sagara, D. Ubben, M. Cousin, F. Oladiran, O. Sander, B. Ogutu

Pathology, East Africa

Background: Asymptomatic carriers of Plasmodium falciparum serve as a reservoir of parasites for malaria transmission. Identification and treatment of asymptomatic carriers within a region may reduce the parasite reservoir and influence malaria transmission in that area.

Methods: Using computer simulation, this analysis explored the impact of community screening campaigns (CSC) followed by systematic treatment of P. falciparum asymptomatic carriers (AC) with artemether-lumefantrine (AL) on disease transmission. The model created by Okell et al (originally designed to explore the impact of the introduction of treatment with artemisinin-based combination therapy on malaria endemicity) was modified to represent CSC and treatment of …

Diagnosis Of Langerhans Cell Histiocytosis On Fine Needle Aspiration Cytology: A Case Report And Review Of The Cytology Literature, Neeta Kumar, Shahin Sayed, Sudhir Vinayak

Pathology, East Africa

A case of multifocal Langerhans cell histiocytosis in a two-year-old child is presented where fine needle aspiration was helpful in achieving a rapid and accurate diagnosis in an appropriate clinical and radiological setting. This can avoid unnecessary biopsy and guide the management especially where access to histopathology is limited. The highly characteristic common and rare cytological features are highlighted with focus on differential diagnoses and causes of pitfalls.

Protein Kinase C Δ Is Critical For Nucleotide Excision Repair Of Cyclobutane Pyrimidine Dimers, Christopher Michael Negro

Master's Theses

Nucleotide excision repair (NER) is the process by which cells identify and repair bulky, helix-distorting DNA lesions such as ultraviolet (UV) radiation-induced cyclobutane pyrimidine dimers (CPD) and 6-4 photoproducts (6-4PP). NER in human cells is a complex biochemical process requiring several complementation groups. Defects in complementation group genes result in rare, autosomal recessive cancer syndromes such as xeroderma pigmentosum (XP), cockayne syndrome (CS), and trichothiodystrophy, supporting the tumor suppressive effects of NER. Protein Kinase C delta (PKCδ) expression is lost in squamous cell carcinomas where it functions as a tumor suppressor gene. Additionally, in response to UV radiation, PKCδ is …

Identification Of Patient Recovery Patterns After Cardiovascular Surgery Based On Laboratory Tests Results, Alcides Ricardo Santander Mercado

USF Tampa Graduate Theses and Dissertations

In this dissertation is proposed a methodology to identify patient's recovery patterns after cardiovascular surgery based on laboratory tests results. The main purpose is to enhance the understanding of the manifestations of postsurgical complications in patients who underwent cardiovascular surgery. The analysis of patients' recovery process is based on the relationship between plasma calcium, ionized calcium and platelet count over time.

Laboratory results from the James A. Haley Veterans' Hospital databases, related to patients admitted to the Surgical Intensive Care Unit (SICU) after cardiac surgery (coronary artery bypass, aortic value replacement and mitral valve replacement), are used. These databases contain …

The Effects Of Manipulating Conditioned Establishing Operations On The Acquisition Of Mands In Children With Autism Spectrum Disorders, Claudia Troconis

USF Tampa Graduate Theses and Dissertations

In Verbal Behavior, Skinner (1957) suggested that each verbal operant has independent response functions, in which acquiring one does not automatically result in the other, unless transfer between the verbal operants is directly trained. Although several researchers have shown that mands and tacts are functionally independent, more recent research has demonstrated that mands may emerge following tact training. However, this research has not clarified the influence of establishing operations on the emergence of pure mands following tact training. Therefore, the present study investigated the effects of tact training on the acquisition of impure and pure mands in children with autism …

The Impact Of Hospice And Dementia Special Care Units On End-Of-Life Care For Individuals With Dementia, Catherine Elizabeth Mccarty

USF Tampa Graduate Theses and Dissertations

ABSTRACT

Hospice and Dementia Special Care Units (DSCUs) have been shown to be gold standards of care for individuals who are dying and for those with dementia in nursing homes. Using a retrospective administrator and family survey, this study investigated whether the processes of care used in hospice and DSCUs are associated with increased quality of end of life (EOL) care for individuals with dementia. A convenience sample of 17 facilities in four states (FL, PA, MD and MA) was included in the study. Nursing home administrators were surveyed between September 2008 and October 2009. The administrators identified 116 family …

Assessing The Relationship Of Monocytes With Primary And Secondary Dengue Infection Among Hospitalized Dengue Patients In Malaysia, 2010: A Cross-Sectional Study, Benjamin Glenn Klekamp

USF Tampa Graduate Theses and Dissertations

Dengue, a group of four similar viruses transmitted through the bite of a mosquito, is estimated to infect upwards of 100 million annually in over 100 nations throughout the global equatorial belt. Distribution of global dengue is highly skewed as Southeast Asian and Western Pacific regions endure 75% of the global dengue burden. Similar to other regional countries, Malaysia has been rapidly urbanizing, which has supported a hyperendemic dengue state.

The biological pathway by which dengue infection causes a wide range of clinical manifestations, spanning asymptomatic to life-threatening severe complications, is not comprehensively understood. Historically, severe dengue complications have primarily …

An Evaluation Of Booster Training Using Video Modeling With Foster Parents, Anna Katherine Caravello

USF Tampa Graduate Theses and Dissertations

In order for foster parents to be prepared to manage problem behavior and develop a positive relationship with a child in their home, local foster care agencies require these parents to attend parent training classes. Unfortunately, even foster care agencies that offer empirically validated parent training courses are unable to prevent the parents' performance from decreasing over time (Cowart, Iwata, & Poynter, 1984; Forehand & King, 1977; Mueller et al., 2003). However, researchers have created booster training sessions to counteract this issue. Booster training sessions allow participants to attend a brief refresher course on skills they have previously learned. Another …

The Impact Of Pharmacy Work Design On Pharmacist Productivity, Nicholas Allen Coblio

USF Tampa Graduate Theses and Dissertations

Healthcare costs in the United States continue to grow at an alarming rate. Concerning the cost of medications, there are a number of factors that drive these costs. While personnel costs are not the largest of these, they do contribute a significant portion. The cost of the cognitive component of order processing by pharmacists can range from three dollars to over six dollars per prescription depending on the production throughput of the pharmacist.

Studies at the organization which was the focus of the research, as well as reports in the literature, indicated that work disruption and other environmental factors could …

Analytical Methods To Support Risk Identification And Analysis In Healthcare Systems, Laila Nadime Cure Vellojin

USF Tampa Graduate Theses and Dissertations

Healthcare systems require continuous monitoring of risk to prevent adverse events. Risk analysis is a time consuming activity that depends on the background of analysts and available data. Patient safety data is often incomplete and biased. This research proposes systematic approaches to monitor risk in healthcare using available patient safety data. The methodologies combine traditional healthcare risk analysis methods with safety theory concepts, in an innovative manner, to allocate available evidence to potential risk sources throughout the system. We propose the use of data mining to analyze near-miss reports and guide the identification of risk sources. In addition, we propose …

Caregivers of individuals with disabilities in the United States have been reported to experience additional hardships than families with typical children as they attempt to balance family and work (Parish, Rose, Grinstein-Weiss, Richman, & Andrews, 2008). In this study, 31 caregivers of individuals with intellectual disabilities from the United States and 225 from the Czech Republic completed a qualitative quality of life survey. Similarities in the two groups were found in reported gains and losses from caregiving responsibilities. Differences in perceived spirituality, personal sense of peace and serenity, life optimism, ability to rejoice in life, personal life perspective, health, financial …

Estimating The Reproductive Numbers For The 2008-2009 Cholera Outbreaks In Zimbabwe, Zindoga Mukandavire, Shu Liao, Jin Wang, Holly Gaff, David L. Smith, J. Glenn Morris Jr.

Biological Sciences Faculty Publications

Cholera remains an important global cause of morbidity and mortality, capable of causing periodic epidemic disease. Beginning in August 2008, a major cholera epidemic occurred in Zimbabwe, with 98,585 reported cases and 4,287 deaths. The dynamics of such outbreaks, particularly in nonestuarine regions, are not well understood. We explored the utility of mathematical models in understanding transmission dynamics of cholera and in assessing the magnitude of interventions necessary to control epidemic disease. Weekly data on reported cholera cases were obtained from the Zimbabwe Ministry of Health and Child Welfare (MoHCW) for the period from November 13, 2008 to July 31, …

Abstract

Background Definitive repair of recurrent ventral hernias using abdominal wall reconstruction techniques is an essential tool in the armentarium for general and plastic surgeons. Ramirez 1 et al describes the “component separation” technique to mobilize the rectus-abdominus internal oblique and external oblique flap to correct the defect. The recurrence rate of incisional hernias increases to 20% after gastric bypass or extensive weight loss.2 The incidence of ventral hernias after failed recurrent hernia repair increases to 40%.3 It has been reported that utilizing the sliding myofascial flap repair technique, the recurrence rate was reduced to 8.5%.4

P16 Ink4a Immunocytochemistry On Cell Blocks As An Adjunct To Cervical Cytology: Potential Reflex Testing On Specially Prepared Cell Blocks From Residual Liquid-Based Cytology Specimens, Vinod B. Shidham, Ravi Mehrotra, George Varsegi, Krista L. D'Amore, Bryan Hunt, Raj Narayan

Department of Pathology

Background: p16 INK4a (p16) is a well-recognized surrogate molecular marker for human papilloma virus (HPV) related squamous dysplasia. Our hypothesis is that the invasive interventions and related morbidities could be avoided by objective stratification of positive cytologic interpretations by p16 immunostaining of cell block sections of cytology specimens.

Materials and Methods: Nuclear immunoreactivity for p16 was evaluated in cell block sections in 133 adequate cases [20 negative for intraepithelial lesion or malignancy, 28 high-grade squamous intraepithelial lesion (HSIL), 50 low-grade squamous intraepithelial lesion (LSIL), 21 atypical squamous cells, cannot exclude HSIL (ASC-H), and 14 atypical squamous cells of undetermined significance …

Cathepsin B: A Potential Prognostic Marker For Inflammatory Breast Cancer, Mohamed A. Nouh, Mona M. Mohamed, Mohamed El-Shinawi, Mohamed A. Shaalan, Dora Cavallo-Medved, Hussein M. Khaled, Bonnie F. Sloane

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Inflammatory breast cancer (IBC) is the most aggressive form of breast cancer. In non-IBC, the cysteine protease cathepsin B (CTSB) is known to be involved in cancer progression and invasion; however, very little is known about its role in IBC.

Methods

In this study, we enrolled 23 IBC and 27 non-IBC patients. All patient tissues used for analysis were from untreated patients. Using immunohistochemistry and immunoblotting, we assessed the levels of expression of CTSB in IBC versus non-IBC patient tissues. Previously, we found that CTSB is localized to caveolar membrane microdomains in cancer cell lines including IBC, and …

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

The infrarenal abdominal aorta exhibits increased disease susceptibility relative to other aortic regions. Allograft studies exchanging thoracic and abdominal segments showed that regional susceptibility is maintained regardless of location, suggesting substantial roles for embryological origin, tissue composition and site-specific gene expression.

Results

We analyzed gene expression with microarrays in baboon aortas, and found that members of the HOX gene family exhibited spatial expression differences. HOXA4 was chosen for further study, since it had decreased expression in the abdominal compared to the thoracic aorta. Western blot analysis from 24 human aortas demonstrated significantly higher HOXA4 protein levels in thoracic …

Unilateral Thalamic Infarction Presenting As Vertical Gaze Palsy: A Case Report, Muhib Khan, Christos Sidiropoulos, Panayiotis Mitsias

Wayne State University Associated BioMed Central Scholarship

Abstract

Introduction

Vertical gaze palsy is a recognized manifestation of midbrain lesions. It rarely is a consequence of unilateral thalamic infarction.

Case presentation

We report the case of a 48-year-old African-American woman who presented to our facility with vertical gaze palsy and evidence of left medial thalamic infarct on diffusion-weighted imaging without coexisting midbrain ischemia. The etiology of infarct was determined to be small vessel disease after extensive investigation.

Conclusions

This report suggests a possible role of the thalamus as a vertical gaze control center. Clinicoradiological studies are needed to further define the role of the thalamus in vertical gaze …

Lack Of An Association Of Mir-938 Snp In Iddm10 With Human Type 1 Diabetes, Xiaofan Mi, Hongzhi He, Yangxin Deng, Abert M. Levin, Jin-Xiong She, Qing-Sheng Mi, Li Zhou

Wayne State University Associated BioMed Central Scholarship

Abstract

MicroRNAs (miRNAs) are a newly discovered type of small non-protein coding RNA that function in the inhibition of effective mRNA translation, and may serve as susceptibility genes for various disease developments. The SNP rs12416605, located in human type 1 diabetes IDDM10 locus, changes the seeding sequence (UGU[G/A]CCC) of miRNA miR-938 and potentially alters miR-938 targets, including IL-16 and IL-17A. In an attempt to test whether miR-938 may be a susceptibility gene for IDDM10, we assessed the possible association of the miR-938 SNP with T1D in an American Caucasian cohort of 622 patients and 723 healthy controls by TaqMan assay. …

Inhibition Of Cathepsin B Activity Attenuates Extracellular Matrix Degradation And Inflammatory Breast Cancer Invasion, Bernadette C. Victor, Arulselvi Anbalagan, Mona M. Mohamed, Bonnie F. Sloane, Dora Cavallo-Medved

Wayne State University Associated BioMed Central Scholarship

Abstract

Introduction

Inflammatory breast cancer (IBC) is an aggressive, metastatic and highly angiogenic form of locally advanced breast cancer with a relatively poor three-year survival rate. Breast cancer invasion has been linked to proteolytic activity at the tumor cell surface. Here we explored a role for active cathepsin B on the cell surface in the invasiveness of IBC.

Methods

We examined expression of the cysteine protease cathepsin B and the serine protease urokinase plasminogen activator (uPA), its receptor uPAR and caveolin-1 in two IBC cell lines: SUM149 and SUM190. We utilized a live cell proteolysis assay to localize in real …

The Potential Role Of Innate Immunity In The Pathogenesis Of Post-Operative Adhesions, Jennell White

Wayne State University Dissertations

Post-operative adhesion development occurs in the vast majority of patients following abdominal surgery and is a natural occurrence of peritoneal-wound healing. These fibrous bands may form within the first 5-7 days post-surgery and have the ability to cause a distortion in the normal anatomical positioning of abdominal organs. Consequently, adhesions are major contributors to small bowel obstruction, infertility, and severe pelvic and abdominal pain. Physiological processes responsible for adhesion formation remain obscure though it is believed to involve cell migration, proliferation, and differentiation of several cell types including mesothelial cells, fibroblasts, and inflammatory and immune cells. Substances released from these …

Consultation Etiquette In General Practice: A Qualitative Study Of What Makes It Different For Lay Cancer Caregivers, Geoffry K. Mitchell, Moyez Jiwa, Afaf Girgis

Medical Papers and Journal Articles

Background: It is commonplace for lay caregivers to overlook their own health concerns when supporting someone with advanced cancer. During this time, caregivers’ needs as patients are often marginalised by health professionals, including General Practitioners (GPs), who may miss the breadth of caregivers’ needs by focusing on the practicalities of caregiving. GPs traditionally rely on patients to raise their concerns, and then respond to these concerns, but caregivers as patients may be disinclined to cue their GP. The norms of engagement when caregivers consult their GP are less defined, and how they interact with their GP regarding their own health …

Opposing Actions Of Extracellular Signal-Regulated Kinase (Erk) And Signal Transducer And Activator Of Transcription 3 (Stat3) In Regulating Microtubule Stabilization During Cardiac Hypertrophy, D Ng, I Ng, B Badrian, T Tsoutsman, J Mcmullen, C Semsarian, M Bogoyevitch

Medical Papers and Journal Articles

Excessive proliferation and stabilization of the microtubule (MT) array in cardiac myocytes can accompany pathological cardiac hypertrophy, but the molecular control of these changes remains poorly characterized. In this study, we examined MT stabilization in two independent murine models of heart failure and revealed increases in the levels of post-translationally modified stable MTs, which were closely associated with STAT3 activation. To explore the molecular signaling events contributing to control of the cardiac MT network, we stimulated cardiac myocytes with an a-adrenergic agonist phenylephrine (PE), and observed increased tubulin content without changes in detyrosinated (glutubulin) stable MT’s. In contrast, the hypertrophic …

Lifestyle And Demographic Correlates Of Poor Mental Health In Early Adolescence, Monique Robinson, Garth Kendall, Peter Jacoby, Beth P. Hands, Lawrence Beilin, Sven Silburn, Steve Zubrick, Wendy Oddy

Health Sciences Papers and Journal Articles

Aim: To determine the constellation of lifestyle and demographic factors that are associated with poor mental health in an adolescent population.

Methods: The Raine Study 14-year follow-up involved primary care givers and their adolescent children (n = 1860). The Child Behaviour Checklist (CBCL) was used to assess adolescent mental health. We examined diet, socio-demographic data, family functioning, physical activity, screen use and risk-taking behaviours with mental health outcomes using linear regression.

Results: Adolescents with higher intakes of meat and meat alternatives and ‘extras’ foods had poorer mental health status. Adverse socioeconomic conditions, higher hours of screen use and ever partaking …

Visualizing The Role Of Cbl-B In Control Of Islet-Reactive Cd4 T Cells And Susceptibility To Type 1 Diabetes, Gerard F. Hoyne, Eleanor Flening, Mehmet Yabas, Charis Teh, John A. Altin, Katrina Randall, Christine B F Thien, Wallace Y. Langdon, Christopher C. Goodnow

Health Sciences Papers and Journal Articles

The E3 ubiquitin ligase Cbl-b regulates T cell activation thresholds and has been associated with protecting against Type 1 diabetes, but its in vivo role in the process of self-tolerance has not been examined at the level of potentially auto-aggressive CD4+ T cells. Here we visualize the consequences of Cbl-b deficiency on self-tolerance to lysozyme antigen expressed in transgenic mice under control of the insulin promoter (insHEL). By tracing the fate of pancreatic islet-reactive CD4+ T cells in pre-diabetic 3A9-TCR x insHEL double-transgenic mice, we find that Cbl-b deficiency contrasts with AIRE or IL-2 deficiency because it does not affect …

Association Of Retinoic Acid Receptor Genes With Meningomyelocele, Phong X Tran, Kit Sing Au, Alanna C Morrison, Jack M Fletcher, Kathryn K Ostermaier, Gayle H Tyerman, Hope Northrup

Faculty, Staff and Student Publications

BACKGROUND: Neural tube defects (NTDs) occur in as many as 0.5-2 per 1000 live births in the United States. One of the most common and severe neural tube defects is meningomyelocele (MM) resulting from failed closure of the caudal end of the neural tube. MM has been induced by retinoic acid teratogenicity in rodent models. We hypothesized that genetic variants influencing retinoic acid (RA) induction via retinoic acid receptors (RARs) may be associated with risk for MM.

METHODS: We analyzed 47 single nucleotide polymorphisms (SNPs) that span across the three retinoic acid receptor genes using the SNPlex genotyping platform. Our …
