Head Injury Risk And Car Seat Use For Children In Collisions, Peyton A. Schroeder, M.J. Skhurm, D. Fraser, K. Mcclafferty
Western Research Forum
Background: Motor vehicle collisions (MVCs) are the leading cause of death for people under the age of 17 years. Almost 80% of rear seat motor vehicle passengers are children. Previous studies have shown that a large fraction of injuries to children in MVCs involved the head and chest. In this study, the hypothesis that children under the age of eight using a forward-facing child restraint system (FFCRS) will have more severe head injuries than children using any other type of restraints in an MVC was tested.
Methods: Several datasets obtained from Transport Canada and Level 1 Pediatric Trauma Centre emergency …

Investigating AMPK signalling regulation of autophagy in a model of ovarian tumour dormancy
Jeremi Laski and Trevor G. Shepherd
Background:
Ovarian cancer is the most deadly gynecologic malignancy in women. A particular subset of this disease, epithelial ovarian cancer (EOC), is responsible for over 70% of all diagnosed ovarian cancer cases, yet the mechanisms governing disease progression are poorly understood. One of the unique hallmarks of EOC metastasis lies in the process of spheroid formation, whereby tumour cells aggregate into larger 3D structures. These EOC spheroids have been shown to be metabolically dormant, while concurrently up-regulating autophagy (cellular waste …

Background: The purpose of this study is to better understand nurses' performance based on training processes. This will determine if group training will increase performance compared to independent training through a shared mental model in a contextual setting of unpredictability mediated by the effects of nurses’ perceptions of patient safety climate. A mixed methods study is conducted using critical discourse analysis of organizational documentation and semi-structured interviews to determine measures of contextual setting when identifying and treating sex trade workers.
Methods: Pragmatic study will analyze two groups of 125 nurses each determining the impact of group and individual …
Developing Novel Therapeutics For Bacterial Lung Infections, Brandon J. Baer, Ruud Veldhuizen, Cory Yamashita
Developing Novel Therapeutics For Bacterial Lung Infections, Brandon J. Baer, Ruud Veldhuizen, Cory Yamashita
Western Research Forum
Background: Bacterial lung infections are leading causes of death worldwide. Unfortunately, increasing resistance to antibiotics and the inflammation often accompanying these infections are leading to poor outcomes despite antibiotic intervention. Complicating treatment further, the tree-like branching structure of the lung makes drug delivery to distal sites of infection difficult. Our research aims to address these challenges by developing new therapeutics and new tools to improve and assess drug delivery, bacterial killing and inflammation. Our therapy combines host defense peptides, which have been shown to kill antibiotic-resistant bacteria and down regulate inflammation, with a pulmonary vehicle, exogenous surfactant, that can improve …
Perioperative Gait Analysis After Total Hip Arthroplasty: Does Outpatient Surgery Compromise Patient Outcomes?, Bryn O. Zomar, Susan W. Hunter, Dianne Bryant, Brent A. Lanting, James L. Howard
Perioperative Gait Analysis After Total Hip Arthroplasty: Does Outpatient Surgery Compromise Patient Outcomes?, Bryn O. Zomar, Susan W. Hunter, Dianne Bryant, Brent A. Lanting, James L. Howard
Western Research Forum
Background: There has been a continuing trend towards decreasing the length of hospital stay for patients undergoing total hip arthroplasty (THA). Outpatient procedures, discharging patients on the same day as surgery, have now become possible yet little research has been done to examine the impact this might have on patients during early recovery. We aimed to investigate the impact of discharge time on gait and patient-reported outcomes in the early post-operative period.
Methods: We measured gait velocity, stride length, single-limb support and single-limb support symmetry preoperatively, at discharge from the hospital, and two-, six- and 12-weeks postoperatively. Participants also completed …
Differentiating Midbrain Structures In Parkinson’S Disease Using Magnetic Resonance Imaging, Erind Alushaj
Differentiating Midbrain Structures In Parkinson’S Disease Using Magnetic Resonance Imaging, Erind Alushaj
Western Research Forum
Background: This study aims to differentiate two midbrain structures: substantia nigra pars compacta (SNc) and ventral tegmental area (VTA) in patients with early-stage Parkinson’s Disease (PD) using magnetic resonance imaging (MRI). The SNc degenerates earlier in PD causing motor symptoms; whereas, VTA degeneration occurs later leading to non-motor symptoms. Conventionally, the SNc and VTA project to the dorsal and ventral striatum respectively. Evidence suggests this model may be overly simplistic since the dorsal striatum has uneven dopamine loss in PD. So, the dorsal striatum was segmented into six functional subregions and only the caudal motor subregion showed early changes …
Multisensory Integration And Autistic Traits Using Non-Sociolinguistic Information, Sébastien A. Lauzon, Samantha E. Schulz, Zack I. Cohen, Ryan A. Stevenson
Multisensory Integration And Autistic Traits Using Non-Sociolinguistic Information, Sébastien A. Lauzon, Samantha E. Schulz, Zack I. Cohen, Ryan A. Stevenson
Western Research Forum
Background: Sensory processing issues are one of the most common complaints in autism spectrum disorder (ASD). One area of sensory difficulties in ASD that has been the focus of intense research in recent years is multisensory integration (MSI), or the ability to bind auditory and visual information into a single, unified percept. While integration of social or linguistic information is consistently shown to be an area of difficulty in ASD, results are less clear with simple, non-sociolinguistic stimuli. This study aims to address this ambiguity by determining whether MSI of non-sociolinguistic sensory information is related to traits and symptomatology …
Associated Factors Of Cam Use In Adults With Chronic Pain: A Scoping Review, Jessica Lachance
Associated Factors Of Cam Use In Adults With Chronic Pain: A Scoping Review, Jessica Lachance
Western Research Forum
Background: Chronic pain is a multifaceted, complex disorder resulting in disability that poses a significant impact on the quality of life for those afflicted and serious effects on society and the health care system at large. Available conventional treatments for chronic pain are not fully effective, resulting in more people turning to Complementary and Alternative Medicine to manage it. This area encompasses any medical system or therapy that resides outside of the conventional medical treatments of a given society, for example: acupuncture, chiropractic, massage, or Traditional Chinese Medicine. One important direction of research in this area is to understand the …
Effects Of Mental Imagery Use On Anxiety, Confidence, Mental Well-Being, And Performance In Track And Field Athletes, Sarah J. Deck, Despina Kouali, Craig Hall Dr.
Effects Of Mental Imagery Use On Anxiety, Confidence, Mental Well-Being, And Performance In Track And Field Athletes, Sarah J. Deck, Despina Kouali, Craig Hall Dr.
Western Research Forum
Background: Student athletes can experience a number of stressors above and beyond those of their classmates, one being competition anxiety in their specific sport, which is common among varsity athletes (Storch, Storch, Killiany, & Roberti, 2005). Unfortunately, the tools to help with the demands of their sport mentally are often overlooked by not only the athletes, but their coaches, teammates, and supporters. The purpose of the present study was to introduce imagery as a tool to help deal with competition anxiety (i.e., fear of failure), and to improve confidence, mental well-being, and performance.
Methods: Two female varsity level throwers ( …

Molecular beacons are important bioanalytical probes which are most often
constructed from a single-stranded oligonucleotide which has been labeled at
opposite termini with a fluorophore and a quencher. When the fluorophore and
quencher are in close proximity, no fluorescence is observed due to FRET
(Fluorescence Resonance Energy Transfer). DABCYL (4-dimethylaminoazobenzene-
4'-carboxylic acid) has been used as a quencher in the molecular beacon to absorbs
excitation energy from a fluorophore and to dissipate the energy as heat. However,
DABCYL is unable to form a base-pair and is conventionally placed as an overhanging
residue. This produces a derivative wherein the chromophore has …

Clarifying Dopaminergic Projections Of The Ventral Tegmental Area And Substantia Nigra In Humans Using Structural Magnetic Resonance Imaging, Nicholas Handfield-Jones
Clarifying Dopaminergic Projections Of The Ventral Tegmental Area And Substantia Nigra In Humans Using Structural Magnetic Resonance Imaging, Nicholas Handfield-Jones
Western Research Forum
Background
Dopaminergic (DA) pathways from the human midbrain to the striatum mediate movement, decision making, learning, and reward processing. Classically, the scientific consensus has been that there are two main DA pathways: the nigrostriatal and the mesolimbic pathways. In the nigrostriatal pathway, the substantia nigra par compacta (SNc) sends DA to the dorsal striatum (DS), and in the mesolimbic pathway, the ventral tegmental area (VTA) sends DA to the ventral striatum (VS) as well as prefrontal and limbic cortices. Recent findings, however, cast doubt on the accuracy of this model. It seems likely these DA projections are more overlapping and …
Navigating Through The Challenges Of Healthcare Simulated Education, Ryan Chan, Adam Morse
Navigating Through The Challenges Of Healthcare Simulated Education, Ryan Chan, Adam Morse
Western Research Forum
Background: The use of simulation as an adjunct tool for student learning and development in addition to traditional didactic teaching modalities has been traditionally favored by health care education. However, evidence suggest that there are limitations to the current use of simulation and thoughtful considerations must be made to leverage the current use of simulation to promote further learning strategies including the use of haptic technology. The aim of this research is to examine the strengths and limitations of haptic technology and to identify opportunities for future research relating to the use and adaptation of haptic technology as part of …
