X-Linked Serotonin 2c Receptor Is Associated With A Non-Canonical Pathway For Sudden Unexpected Death In Epilepsy, Cory A Massey, Samantha J Thompson, Ryan W Ostrom, Janice Drabek, Olafur A Sveinsson, Torbjörn Tomson, Elisabeth A Haas, Othon J Mena, Alica M Goldman, Jeffrey L Noebels

Faculty, Staff and Students Publications

Sudden Unexpected Death in Epilepsy is a leading cause of epilepsy-related mortality, and the analysis of mouse Sudden Unexpected Death in Epilepsy models is steadily revealing a spectrum of inherited risk phenotypes based on distinct genetic mechanisms. Serotonin (5-HT) signalling enhances post-ictal cardiorespiratory drive and, when elevated in the brain, reduces death following evoked audiogenic brainstem seizures in inbred mouse models. However, no gene in this pathway has yet been linked to a spontaneous epilepsy phenotype, the defining criterion of Sudden Unexpected Death in Epilepsy. Most monogenic models of Sudden Unexpected Death in Epilepsy invoke a failure of inhibitory synaptic …

An imbalance in the crosstalk between the host and gut microbiota affects the intestinal barrier function, which results in inflammatory diseases and colorectal cancer. The colon epithelium protects itself from a harsh environment and various pathogenic organisms by forming a double mucus layer, primarily comprising mucins. Recent studies are focusing on how dietary patterns alter the gut microbiota composition, which in turn regulates mucin expression and maintains the intestinal layers. In addition, modulation of gut microbiota by microbiotic therapy (involving fecal microbiota transplantation) has emerged as a significant factor in the pathologies associated with dysbiosis. Therefore, proper communication between host …

A Right Para-Tracheal Mass Extending Into The Anterior Mediastinum: An Anesthetic Management Conundrum, Andres Bacigalupo Landa, Kritika Krishnamurthy, Howard S Goldman

Faculty, Staff and Students Publications

The anesthetic management of patients with a mediastinal mass represent a challenge due to the potential for difficult ventilation and intubation, as well as the risk of cardiovascular collapse upon induction of general anesthesia. Different strategies and alternatives have been described. We present the case of a 70-year-old man with a right para-tracheal mass extending into the anterior mediastinum with 90% mid-tracheal lumen obstruction who was successfully managed with venous-venous extra-corporeal membrane oxygenation (ECMO) during mass debulking and tracheal stent placement.

Does Accurate Data, Identifying Obese Patients Impact Nurse Safety And Hospital Finances?, Kim Mcclean Jan 2021

Does Accurate Data, Identifying Obese Patients Impact Nurse Safety And Hospital Finances?, Kim Mcclean

Theses: Doctorates and Masters

Healthcare staff who manage obese patients are at increased risk of sustaining patient handling injuries, and this risk is anticipated to intensify as projected Australian obesity rates increase to 42% by the year 2035 and obese patients admitted to hospitals also increase. High cost burdens to healthcare organisations will result due to increased funding requirements for bariatric risk management solutions and growing costs of workers’ compensation claims of injured staff. Five (5) studies explored if identification of obese patients impacts the safety of nurses and other healthcare staff who manage obese patients and investigated the accuracy of obesity data recorded …


Unravelling The Potential Applications Of Extracellular Vesicles For The Clinical Management Of Melanoma Patients, Michael Edward Clark Jan 2021

Unravelling The Potential Applications Of Extracellular Vesicles For The Clinical Management Of Melanoma Patients, Michael Edward Clark

Theses: Doctorates and Masters

Metastatic melanoma is the third most common cancer in Australia with global incidence increasing. After decades without effective systemic treatments for advanced melanoma, the advent of targeted and immune therapies has substantially improved patient survival. While this is encouraging, further research is needed as the majority of patients treated with targeted therapy ultimately develop drug resistance. Immunotherapy can achieve durable responses in many patients however, not all patients respond to current single or a combination of immune checkpoint inhibitors. Considering the cost and potential toxicities to patients being treated with these therapies, there is an urgent need to develop biomarkers …


The Coaches’ Eye: Exploring Coach Decision-Making During Talent Identification, Alexandra Hannah Roberts Jan 2021

The Coaches’ Eye: Exploring Coach Decision-Making During Talent Identification, Alexandra Hannah Roberts

Theses: Doctorates and Masters

For decades, researchers and practitioners interested in talent identification have discussed the coaches’ eye: the elusive ability that allows some coaches to ‘see’ qualities in an athlete that point to their talent or future potential. While there is significant anecdotal evidence of coaches who possess this ability, there is little empirical research supporting the validity or reliability of the coaches’ eye. Guided by ecological dynamics, this thesis employs mixed methodologies to explore the decision-making that underpins how high-level coaches identify talent in Olympic combat sports. These four studies captured the processes of thirty- four coaches during the talent identification process, …

However, very little is known if the social determinants of health throughout the life�course are associated with metabolic syndrome. The study aimed to explore the association between life-course social determinants of health and metabolic syndrome. The cross-sectional study involved female secondary school teachers living in the state of Johor, Malaysia. The study used available data from the Clustering of Lifestyle risk …


Artisanal Mining Impacts In Urbanized Semi-Arid Environments: Lessons From Historic Arsenic Mining Near San Diego, California, James A. Wright Jan 2021

Artisanal Mining Impacts In Urbanized Semi-Arid Environments: Lessons From Historic Arsenic Mining Near San Diego, California, James A. Wright

Theses

Anomalously elevated arsenic concentrations occur at an abandoned artisanal mine site in an open space recreational park in urban San Diego County, California. Although mining at the site ceased 100 years ago little to no remediation efforts took place leaving shafts, adits, waste piles and derelict infrastructure accessible by inquisitive hikers and adventurers frequenting Black Mountain Open Space Park. This study evaluates the geochemical mechanisms of As transport downgradient from the mine and examines the contribution of both climate and urbanization on the restriction of As mobility. Sediment As concentrations reach 2,320 mg/kg (483 times background crustal concentrations; n=73) along …

An Exploration Of The Relationship Between Aphasia Therapy, Depression And Quality Of Life In Post-Stroke Patients After Rehabilitation At 12 And 26 Weeks After Stroke: A Verse Sub-Study, Alia Rashid Khan Jan 2021

An Exploration Of The Relationship Between Aphasia Therapy, Depression And Quality Of Life In Post-Stroke Patients After Rehabilitation At 12 And 26 Weeks After Stroke: A Verse Sub-Study, Alia Rashid Khan

Theses: Doctorates and Masters

Background: Depression is a common consequence of stroke, and people with aphasia (PWA) post-stroke have a higher risk of developing depression compared to stroke survivors without aphasia. However, current stroke interventions featuring aphasia therapy tend to neglect the effect of the treatment on mood. There is also a lack of evidence on the impact of stroke education and counselling on PWA in early stroke recovery. Additionally, the research on post-stroke depression often excludes or insufficiently describes PWA in study populations. The influence of direct aphasia therapy on depression in PWA is undetermined. This sub-study investigated: i) the effect of …

The Characteristics And Effectiveness Of Treatment For Young Sex Offenders In Australia And New Zealand: A Systematic Review, James Finney

Theses: Doctorates and Masters

Sexual offending by young people presents a serious and devastating issue effecting victims, families, and wider society. This has led investigative efforts to understand the efficacy of treatment programs to cease or at minimum reduce sexual recidivism. Evaluations examining treatment efficacy have predominately been conducted in the United States and Canada, with limited research focused exclusively on young sex offenders in Australia and New Zealand. To address the paucity of information, a systematic review of young sex offender treatment research in Australia and New Zealand was conducted. The systematic review employed a comprehensive search strategy and rigorous vetting procedure, which …


The Adherence To Group B Streptococcus Screening Guidelines Amongst Pregnant Women In Western Australia – A Quantitative Descriptive Analysis, Sabine Pangerl Jan 2021

The Adherence To Group B Streptococcus Screening Guidelines Amongst Pregnant Women In Western Australia – A Quantitative Descriptive Analysis, Sabine Pangerl

Theses: Doctorates and Masters

Colonisation with Group B Streptococci (GBS) is a major risk factor for neonatal infection acquired via vertical transmission during pregnancy, labour, or birth, potentially resulting in significant morbidity and mortality. Universal screening at 35 – 37 weeks gestation for maternal GBS colonisation and the use of intrapartum antibiotic prophylaxis has resulted in substantial reductions in the burden of neonatal Early-Onset GBS Disease (EOGBSD). Women in Western Australia (WA) are offered GBS screening in pregnancy and intrapartum antibiotic prophylaxis. Anecdotal evidence suggests variations in viewpoints and thus low adherence to relevant clinical guidelines amongst midwives and pregnant women in the midwifery …

Power, Perspective And Affordance In Early Childhood Education, Amelia Ruscoe Jan 2021

Power, Perspective And Affordance In Early Childhood Education, Amelia Ruscoe

Theses: Doctorates and Masters

The position of a young child beginning school is unique and precarious. Children are capable of making their own decisions about what to participate in and contribute to, but often guided by adults charged with the responsibility of their education and care. The beliefs and values of these adults are pivotal to what a child may experience but are seldom examined to ascertain what they may or may not afford young children in their early education.

Through examination of the literature, neoliberal reform, developmentally appropriate practice and the quality agenda have surfaced as particularly strong discourses influencing early childhood education. …

Immunotherapy As A Treatment Strategy In Advanced Stage And Recurrent Endometrial Cancer: Review Of Current Phase Iii Immunotherapy Clinical Trials, Ramez N Eskander, Matthew A Powell

2020-Current year OA Pubs

The treatment of advanced stage, metastatic or recurrent endometrial cancer remains a clinically difficult scenario. Although combination carboplatin and paclitaxel is an effective standard-of-care regimen, alternate strategies have shown promise, particularly in biomarker select populations. In an effort to improve oncologic outcomes, investigators are exploring novel immunotherapy combinations. In this review, we discuss the clinical rationale and design of current phase III immuno-oncology clinical trials in patients with advanced stage or recurrent endometrial cancer.
