Furthering The Quality Agenda In Aboriginal Community Controlled Health Services: Understanding The Relationship Between Accreditation, Continuous Quality Improvement And National Key Performance Indicator Reporting, Beverly Sibthorpe, Karen Gardner, Daniel Mcaullay Jan 2016

Furthering The Quality Agenda In Aboriginal Community Controlled Health Services: Understanding The Relationship Between Accreditation, Continuous Quality Improvement And National Key Performance Indicator Reporting, Beverly Sibthorpe, Karen Gardner, Daniel Mcaullay

Research outputs 2014 to 2021

A rapidly expanding interest in quality in the Aboriginal-community-controlled health sector has led to widespread uptake of accreditation using more than one set of standards, a proliferation of continuous quality improvement programs and the introduction of key performance indicators. As yet, there has been no overarching logic that shows how they relate to each other, with consequent confusion within and outside the sector. We map the three approaches to the Framework for Performance Assessment in Primary Health Care, demonstrating their key differences and complementarity. There needs to be greater attention in both policy and practice to the purposes and alignment …


Examination Of The Relationship Between Caesarean Section Births And Attention Deficit Hyperactivity Disorder, Breea M. Rosas Jan 2016

Examination Of The Relationship Between Caesarean Section Births And Attention Deficit Hyperactivity Disorder, Breea M. Rosas

All Master's Theses

Attention Deficit/Hyperactivity Disorder, a neurological disorder characterized by inattentive and hyperactive behaviors, has become increasingly more prevalent (CDC, 2010). Recent research has found associations between this disorder and Caesarean section births (Amiri et al., 2012; Juarez et al., 2008). The current study examined the relationship between C-section birth and self-reported symptoms of ADHD by college students on the Internal Restlessness Scale (Weyandt et al., 2003). Results of the study indicate a significant difference in mean ratings of ADHD symptoms between C-section and vaginally born participants (t = 3.683, p < .000). The current study supports previous findings of a relationship between C-sections and ADHD.


An Algorithm For Extracting The Ppg Baseline Drift In Real-Time, Tuan Ngoc Nguyen Jan 2016

An Algorithm For Extracting The Ppg Baseline Drift In Real-Time, Tuan Ngoc Nguyen

Theses: Doctorates and Masters

Photoplethysmography is an optical technique for measuring the perfusion of blood in skin and tissue arterial vessels. Due to its simplicity, accessibility and abundance of information on an individual’s cardiovascular system, it has been a pervasive topic of research within recent years. With these benefits however there are many challenges concerning the processing and conditioning of the signal in order to allow information to be extracted. One such challenge is removing the baseline drift of the signal, which is caused by respiratory rate, muscle tremor and physiological changes within the body as a response to various stimuli.

Over the years …

Internet Journal of Allied Health Sciences and Practice

In the year 2015, it is estimated that the number of new cases of invasive melanoma will be 42,670 in males and 31,200 in females.1 Melanoma is treatable with early diagnosis; however, more advanced disease has devastating outcomes. For the past decade, two chemotherapy agents, dacarbazine and temozolomide, have been the treatment of choice for advanced stage III or IV melanoma requiring systemic treatment. Interleukin-2 (IL-2) therapy has been used but with serious side effects. More recently, the focus has shifted to monoclonal antibodies and enzyme inhibitors as the main systemic treatment for advanced cutaneous melanoma. This literature review …

Persons with type 1 and type 2 diabetes have increased fracture risk, attributed to deficits in the microarchitecture and strength of diabetic bone, thought to be mediated, in part, by the consequences of chronic hyperglycemia. Therefore, to examine the effects of a glucose-lowering SGLT2 inhibitor on blood glucose (BG) and bone homeostasis in a model of diabetic bone disease, male DBA/2J mice with or without streptozotocin (STZ)-induced hyperglycemia were fed chow containing the SGLT2 inhibitor, canagliflozin (CANA), or chow without drug, for 10 weeks of therapy. Thereafter, serum bone biomarkers were measured, fracture resistance of cortical bone was assessed by …


Perceptions And Attitudes Of A Sample Of Primary Care Patients Receiving Psychological Care From Their Pcp, Nadine Henzes Gowarty Jan 2016

Perceptions And Attitudes Of A Sample Of Primary Care Patients Receiving Psychological Care From Their Pcp, Nadine Henzes Gowarty

PCOM Psychology Dissertations

With millions of Americans suffering from a mental health disorder and slightly more than half receiving treatment, the demand for psychological services far outweighs the number of practitioners available to provide direct care. Therefore, the majority of all primary-care visits are based on psychosocial factors; one third of a PCP’s caseloads consist of patients with mental-health problems. Given the fact that PCPs provide comprehensive psychosocial care, it is important to determine the beliefs and perceptions of their patients. Results from this study identified numerous factors that influence the relationship between patients receiving mental health care from their PCP. Specifically, if …

PURPOSE: To assess the association of dog walking with adolescents' moderate-to-vigorous physical activity (MVPA) and body mass index (BMI), and identify correlates of dog walking.

METHODS/DESIGN: Participants were 12-17year-olds (n=925) from the Baltimore, MD and Seattle, WA regions. Differences in accelerometer-assessed minutes/day of MVPA and self-reported BMI (percentile) were compared among adolescents (1) without a dog (n=441) and those with a dog who (2) did (≥1days/week, n=300) or (3) did not (n=184) walk it. Correlates of (1) dog walking (any vs. none) among adolescents with dogs (n=484), and (2) days/week of dog walking among dog walkers (n=300) were investigated. Potential …


Modulation Of Body Weight By Intestinal Flora In Orphan Nuclear Receptor Shp-/- Mice, Ryan Mifflin Jan 2016

Modulation Of Body Weight By Intestinal Flora In Orphan Nuclear Receptor Shp-/- Mice, Ryan Mifflin

Williams Honors College, Honors Research Projects

The whole-body deletion of small heterodimer partner (SHP) in mice is associated with protection from diet-induced obesity and hepatic steatosis upon feeding of a western diet. This protection was reported to be mediated through decreases in hepatic gene expression for lipogenesis, as well as increases in gene expression for fatty acid oxidation. SHP has been known to regulate the expression of the CYP7A1 gene, encoding the rate-limiting enzyme for bile acid synthesis, thereby altering the bile acid pool. The effects of this altered bile acid profile on the gut microbiome are unknown, as some bacteria in the gut are responsible …

Identifying Mechanisms Of Resistance And Potential Therapeutic Targets For Pediatric Acute Myeloid Leukemia, John Timothy Caldwell Jan 2016

Identifying Mechanisms Of Resistance And Potential Therapeutic Targets For Pediatric Acute Myeloid Leukemia, John Timothy Caldwell

Wayne State University Dissertations

Acute myeloid leukemia (AML) is a potentially devastating disease that can affect people of all ages. While there are certain patient groups that typically have favorable outcomes, in the pediatric population, overall survival (OS) is approximately 70%, leaving much progress to be made. Children with Down syndrome (DS) have a substantially elevated risk for developing AML, especially of the megakaryocytic phenotype (AMKL).

Patients with DS AMKL almost universally harbor a mutation in the gene encoding the GATA1 transcription factor, resulting in the translation of a short-form protein GATA1s, which has been shown to contribute to chemotherapy sensitivity. In contrast, in …

Mammographic density (MD) is a quantitative trait, measurable in all women, and is among the strongest markers of breast cancer risk. The population-based epidemiology of MD has revealed genetic, lifestyle and societal/environmental determinants, but studies have largely been conducted in women with similar westernized lifestyles living in countries with high breast cancer incidence rates. To benefit from the heterogeneity in risk factors and their combinations worldwide, we created an International Consortium on Mammographic Density (ICMD) to pool individual-level epidemiological and MD data from general population studies worldwide. ICMD aims to characterize determinants of MD more precisely, and to evaluate whether …

Conglutins represent the major peanut allergens and are renowned for their resistance to gastrointestinal digestion. Our aim was to characterize the digestion-resistant peptides (DRPs) of conglutins by biochemical and biophysical methods followed by a molecular dynamics simulation in order to better understand the molecular basis of food protein allergenicity. We have mapped proteolysis sites at the N- and C-termini and at a limited internal segment, while other potential proteolysis sites remained unaffected. Molecular dynamics simulation showed that proteolysis only occurred in the vibrant regions of the proteins. DRPs appeared to be conformationally stable as intact conglutins. Also, the overall secondary …

Domain I Of The 5′ Non-Translated Genomic Region In Coxsackievirus B3 Rna Is Not Required For Productive Replication, L. Jaramillo, S. Smithee, S. Tracy, N. M. Chapman Jan 2016

Domain I Of The 5′ Non-Translated Genomic Region In Coxsackievirus B3 Rna Is Not Required For Productive Replication, L. Jaramillo, S. Smithee, S. Tracy, N. M. Chapman

Nebraska Center for Virology: Faculty Publications

Domain I is a cloverleaf-like secondary structure at the 5′ termini of all enterovirus genomes, comprising part of a cis-acting replication element essential for efficient enteroviral replication. 5′ genomic terminal deletions up to as much as 55% of domain I can occur without lethality following coxsackie B virus infections. We report here that the entire CVB structural domain I can be deleted without lethality.

Reversion To Wildtype Of A Mutated And Nonfunctional Coxsackievirus B3cre(2c), Shane Smithee, Steven Tracy, Nora M. Chapman

Nebraska Center for Virology: Faculty Publications

The cis-acting replication element (CRE) in the 2C protein coding region [CRE(2C)] of enteroviruses (EV) facilitates the addition of two uridine residues (uridylylation) onto the virus-encoded protein VPg inorder for it to serve as the RNA replication primer. We demonstrated that coxsackievirus B3 (CVB3) is replication competent in the absence of a native (uridylylating) CRE(2C) and also demonstrated that lackof a functional CRE(2C) led to generation of 5’ terminal genomic deletions in the CVB3 CRE-knock-out (CVB3-CKO) population. We asked whether reversion of the mutated CRE(2C) occurred, thus permitting sustained replication, and when were 5’ terminal deletions generated during replication. Virions …

Replicating Single-Cycle Adenovirus Vectors Generate Amplified Influenza Vaccine Responses, Catherine M. Crosby, William E. Matchett, Stephanie S. Anguiano-Zarate, Christopher A. Parks, Eric A. Weaver, Larry R. Pease, Richard J. Webby, Michael A. Barry

Nebraska Center for Virology: Faculty Publications

Head-to-head comparisons of conventional influenza vaccines with ade- novirus (Ad) gene-based vaccines demonstrated that these viral vectors can mediate more potent protection against influenza virus infection in animal models. In most cases, Ad vaccines are engineered to be replication-defective (RD-Ad) vectors. In contrast, replication-competent Ad (RC-Ad) vaccines are markedly more potent but risk causing adenovirus diseases in vaccine recipients and health care workers. To harness antigen gene replication but avoid production of infectious virions, we de- veloped “single-cycle” adenovirus (SC-Ad) vectors. Previous work demonstrated that SC-Ads amplify transgene expression 100-fold and produce markedly stronger and more persistent immune responses than …


Mycobacterium Tuberculosis Lineage 4 Comprises Globally Distributed And Geographically Restricted Sublineages, David Stucki, Daniela Brites, Leïla Jeljeli, Mireia Coscolla, Gunturu Revathi Jan 2016

Mycobacterium Tuberculosis Lineage 4 Comprises Globally Distributed And Geographically Restricted Sublineages, David Stucki, Daniela Brites, Leïla Jeljeli, Mireia Coscolla, Gunturu Revathi

Pathology, East Africa

Generalist and specialist species differ in the breadth of their ecological niches. Little is known about the niche width of obligate human pathogens. Here we analyzed a global collection of Mycobacterium tuberculosis lineage 4 clinical isolates, the most geographically widespread cause of human tuberculosis. We show that lineage 4 comprises globally distributed and geographically restricted sublineages, suggesting a distinction between generalists and specialists. Population genomic analyses showed that, whereas the majority of human T cell epitopes were conserved in all sublineages, the proportion of variable epitopes was higher in generalists. Our data further support a European origin for the most …

Outcomes Experienced By Patients Presenting With Ventral Hernias And Morbid Obesity In A Surgical Clinic, Margaret A. Plymale

DNP Projects

Surgeons generally agree that morbid obesity is a contraindication to ventral hernia repair surgery due to risk of adverse outcomes. The purpose of this study was to describe the experience of patients with ventral hernia complicated by morbid obesity by reviewing a population of patients that were seen by a surgical service to determine the characteristics of those patients that had favorable and unfavorable outcomes. A retrospective medical record review was conducted of new patients with ventral hernias and morbid obesity (body mass index (BMI ) ≥ 40 kg/m2) seen by one surgical service over a two and …


A Healthy Herd: Addressing The Justifications For Vaccine Denial And Applying The Health Belief Model To The Current Anti-Vaccination Movement, Sarah L. Mchugh Jan 2016

A Healthy Herd: Addressing The Justifications For Vaccine Denial And Applying The Health Belief Model To The Current Anti-Vaccination Movement, Sarah L. Mchugh

Honors Program Theses

The purpose of this thesis is to explore and analyze the existing literature regarding the refusal to receive vaccinations designed specifically to prevent Measles-Mumps-Rubella (MMR), which has spurred a serious public health issue that puts every unvaccinated person at risk. It will investigate the reasons people refuse to get vaccinations for themselves or their children. The analysis of the current situation and the application of the Health Belief Model to the related factors will provide potential explanations regarding how the decision-making process may strengthen efforts towards increasing vaccination rates.


Where Is Pain In The Brain?, Marshall Devor Jan 2016

Where Is Pain In The Brain?, Marshall Devor

Animal Sentience

Key argues that fish cannot experience pain based on (1) brain imaging in humans, (2) consequences of lesions and (3) direct brain stimulation. Imaging indeed shows that pain-relevant signals reach the cortex, but not that they underlie the subjective experience of pain. Lesions and stimulation data are more to the point, but Key paints an idiosyncratic and misleading picture of their effects. S1 and S2 ablation does not eliminate evoked or spontaneous pain, although there may be up- or down-modulation. Likewise, stimulation of pain-associated cortical areas rarely induces pain, and pain almost never occurs at the onset of epileptic seizures. …
