P30. Optimizing Current Steering In Deep Brain Stimulation For Treating Parkinsonian Axial Motor Symptoms, Daphne Hui
Western Research Forum
Background: The proposed study will investigate deep brain stimulation (DBS), of the subthalamic nucleus (STN) to improve gait dysfunctions in advanced Parkinson’s Disease (PD). DBS requires implantation of electrodes into the brain that contain contacts where current traverses to stimulate neurons. Imprecise electrode implantations are inherent in surgical implantation; thus, contributing to the elusiveness of DBS on gait.
Methods: The proposed investigation will divide current between two contacts to receive 0, 30, 50, 70, or 100% of current, to find the best combination to improve gait. Gait changes associated with fractional combinations will be visually assessed with clinical scales ...

It is well established that there are many health risks associated with prolonged sedentary time.1 Unfortunately, research conducted on university students is limited but yet they experience excessive periods of sitting time during class and while studying.
Recently, we investigated the effect of sitting, dynamic sitting, and standing desks on classroom performance of university students.2 Participants performed three 3-minute classroom simulations, one for each of the three desks. The order of the desks and simulations were randomized. Each of the simulations included a different typing and memory task.
Results showed no significant difference in the ...
P35. Investigating The Effect Of Maternal Immune Activation On Sensory Filtering, Social Behaviour And Attention, Faraj Haddad
Western Research Forum
Altered brain development is associated with many neuropsychiatric disorders like Autism Spectrum Disorder (ASD) and schizophrenia. Environmental insults can interfere with neurodevelopment, and a prominent example is maternal infection during pregnancy. Epidemiological studies show that children born to mothers who were infected during pregnancy display a higher risk of developing ASD and schizophrenia, and this effect is mainly due to the maternal immune response. Polyinosinic-polycytidilic acid (Poly I:C) is a double stranded RNA molecule that mimics viral markers and elicits an immune response. When injected in pregnant rodents, this model produces offspring that exhibit core symptoms of ASD ...
Data As A Strategic Resource: Self-Determination, Governance, And The Data Challenge For Indigenous Nations In The United States, Stephanie Carroll Rainie, Jennifer Lee Schultz, Eileen Briggs, Patricia Riggs, Nancy Lynn Palmanteer-Holder
The International Indigenous Policy Journal
Data about Indigenous populations in the United States are inconsistent and irrelevant. Federal and state governments and researchers direct most collection, analysis, and use of data about U.S. Indigenous populations. Indigenous Peoples’ justified mistrust further complicates the collection and use of these data. Nonetheless, tribal leaders and communities depend on these data to inform decision making. Reliance on data that do not reflect tribal needs, priorities, and self-conceptions threatens tribal self-determination. Tribal data sovereignty through governance of data on Indigenous populations is long overdue. This article provides two case studies of the Ysleta del Sur Pueblo and Cheyenne River ...

A Novel Hybrid Imaging System To Aid In Surgical Decision Making, Lawrence Yip, Madeleine Van De Kleut, Ivan Kosik, Astrid Chamson-Reig, Jeffrey Jl Carson
Western Research Forum
Breast cancer accounts for 25% of all cancer cases among women. In breast-conserving surgery, a common treatment, the tumour is excised with a healthy tissue margin. However, detection of the margin can be difficult. Current techniques to guide excision are often insufficient, and re-excision can occur up to 25% of the time.
Photoacoustic imaging is a hybrid imaging modality that combines the advantages of optical imaging and ultrasound while using safe non-ionizing light. This project involves the development of a novel imaging system with a new scanner design to overcome common limitations and provide images to aid in ...
Parental Quality Of Life 10 Years After Their Child’S Epilepsy Diagnosis, 2017 Western University
Parental Quality Of Life 10 Years After Their Child’S Epilepsy Diagnosis, Klajdi Puka, Kathy Nixon Speechley
Western Research Forum
Background: Although the long-term course of childhood epilepsy is favorable in terms of seizure control, patients often face debilitating cognitive and psychosocial deficits that persist even after seizure remission. Pediatric epilepsy also has a large impact on the family and has been shown to be associated with diminished quality of life (QOL) among parents. However, the long-term outcome of parental QOL is unknown. This study aimed to 1) evaluate parental QOL 10 years after their child was diagnosed with epilepsy and 2) identify epilepsy-, child- and family-related characteristics associated with diminished parental QOL.
Methods: Data were derived from the Health-Related ...
Pulmonary Surfactant Fortified With Cath-2 As A Novel Therapy For Bacterial Pneumonia, 2017 University of Western Ontario
Pulmonary Surfactant Fortified With Cath-2 As A Novel Therapy For Bacterial Pneumonia, Brandon J. Baer
Western Research Forum
Background: Bacterial pneumonia is a leading cause of death worldwide, with high mortality rates persisting even after antibiotic treatment. Current treatments for pneumonia involve administration of antibiotics, however after the bacteria are killed they release toxic substances that induce inflammation and lung dysfunction. Host defense peptides represent a potential solution to this problem through their ability to down regulate inflammation. However, effective delivery to the lung is difficult because of the complex branching structure of the airways. My study addresses this delivery problem by using exogenous surfactant, a pulmonary delivery vehicle capable of improving spreading of these peptides throughout the ...

Perception And Responses To Different Forms Of Aqua-Based Exercise Among Older Adults With Osteoarthritis, 2017 Australian Catholic University
Perception And Responses To Different Forms Of Aqua-Based Exercise Among Older Adults With Osteoarthritis, Alison L. Fisken, Debra L. Waters, Wayne A. Hing, Michael Craig Steele, Justin W. Keogh
Osteoarthritis (OA) is prevalent among older adults. Aqua-based exercise is often recommended as a therapeutic intervention. Limited evidence exists on the effectiveness of this form of exercise intervention. Perceptions of pain, mean, and maximum heart rate (HR) responses, ratings of perceived exertion (RPE), and subjective enjoyment to different forms of aqua-based exercise were investigated. Thirteen older adults with documented OA completed five aquatic exercise sessions: body-weight aqua-fitness (AF), body-weight aqua-jogging (AJ), resisted aqua-fitness (RAF), resisted aqua-jogging (RAJ), and hydrotherapy (HYD). HYD was rated most enjoyable with AF deemed as an acceptable alternative. Pain scores immediately postexercise were significantly lower than ...

Cost Variability Of Suggested Generic Treatment Alternatives Under The Medicare Part D Benefit, Rajul A. Patel, Mark P. Walberg, Emily Tong, Florence Tan, Ashley E. Rummel, Joseph A. Woelfel, Sian M. Carr-Lopez, Suzanne M. Galal
BACKGROUND: The substitution of generic treatment alternatives for brand-name drugs is a strategy that can help lower Medicare beneficiary out-of-pocket costs. Beginning in 2011, Medicare beneficiaries reaching the coverage gap received a 50% discount on the full drug cost of brand-name medications and a 7% discount on generic medications filled during the gap. This discount will increase until 2020, when beneficiaries will be responsible for 25% of total drug costs during the coverage gap. OBJECTIVE: To examine the cost variability of brand and generic drugs within 4 therapeutic classes before and during the coverage gap for each 2011 California stand-alone ...

Toward The Global Control Of Human Scabies: Introducing The International Alliance For The Control Of Scabies, Daniel Engelman, Karen Kiang, Olivier Chosidow, James Mccarthy, Claire Fuller, Patrick Lammie, Roderick Hay, Andrew Steer
Daniel T. Engelman MD
Scabies, the human skin disease caused by infestation by the mite Sarcoptes scabiei var. hominis, causes considerable morbidity and mortality through direct effects and as a result of secondary bacterial infection. Scabies is a truly neglected disease, largely absent from the global health agenda, and its huge burden of disease is largely underappreciated. We contend that coordinated, global efforts to control this ubiquitous pathogenic mite are both important and achievable.
