What Are The Barriers And Facilitators To Community Handwashing With Water And Soap? A Systematic Review., Obidimma Ezezika, Jennifer Heng, Kishif Fatima, Ayman Mohamed, Kathryn Barrett

Health Studies Publications

Handwashing with water and soap (HWWS) is an effective method of cleaning and disinfecting the surface of the hands. HWWS is effective in infection control and prevention transmission, such as in Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). However, rates of handwashing compliance vary globally. This systematic review aimed to identify the barriers and facilitators to community HWWS globally. We conducted a comprehensive search strategy in OVID Medline, OVID Embase, Web of Science Core Collection, and Scopus using keywords and subject headings related to handwashing. Studies were excluded if they reported hand hygiene among healthcare or food service workers, considered …

The Roles Of Family Physicians During A Pandemic., Maria Mathews, Leslie Meredith, Dana Ryan, Lindsay Hedden, Julia Lukewich, Emily G Marshall, Richard Buote, Lauren Moritz, Sarah Spencer, Shabnam Asghari, Judith B Brown, Thomas R Freeman, Paul S Gill, Rita K Mccracken, Madeleine Mckay, Bridget Ryan, Shannon L Sibbald, Stephen Wetmore, Eric Wong

Health Studies Publications

Family physicians play important roles throughout all stages of a pandemic response; however, actionable descriptions outlining these roles are absent from current pandemic plans. Using a multiple case study design, we conducted a document analysis and interviewed 68 family physicians in four Canadian regions. We identified roles performed by family physicians in five distinct stages of pandemic response: pre-pandemic, phased closure and re-opening, acute care crisis, vaccination, and pandemic recovery. In addition to adopting public health guidance to ensure continued access to primary care services, family physicians were often expected to operationalize public health roles (eg, staffing assessment centres), modulate …

Social And Economic Capital As Effect Modifiers Of The Association Between Psychosocial Stress And Oral Health, Abby L J Hensel, Noha Gomaa

Dentistry Publications

OBJECTIVES: To assess the extent of the association of psychosocial stress with oral health in an Ontario population stratified by age groups, and whether any association is modified by indicators of social and economic capital.

METHODS: We retrieved data of 21,320 Ontario adults, aged 30-74 years old, from the Canadian Community Health Survey (CCHS: 2017-2018), which is a Canada-wide, cross-sectional survey. Using binomial logistic regression models that adjusted for age, sex, education, and country of birth, we examined the association of psychosocial stress (indicated by perceived life stress) with inadequate oral health (indicated as having at least one of the …

Estimation Of Free Water-Corrected Microscopic Fractional Anisotropy., Nico J J Arezza, Tales Santini, Mohammad Omer, Corey A Baron

Medical Biophysics Publications

Water diffusion anisotropy MRI is sensitive to microstructural changes in the brain that are hallmarks of various neurological conditions. However, conventional metrics like fractional anisotropy are confounded by neuron fiber orientation dispersion, and the relatively low resolution of diffusion-weighted MRI gives rise to significant free water partial volume effects in many brain regions that are adjacent to cerebrospinal fluid. Microscopic fractional anisotropy is a recent metric that can report water diffusion anisotropy independent of neuron fiber orientation dispersion but is still susceptible to free water contamination. In this paper, we present a free water elimination (FWE) technique to estimate microscopic …

Dentate Gyrus Integrity Is Necessary For Behavioral Pattern Separation But Not Statistical Learning, Helena Shizhe Wang, R. Shayna Rosenbaum, Stevenson Baker, Claire Lauzon, Laura Batterink, Stefan Köhler

Brain and Mind Institute Researchers' Publications

Pattern separation, the creation of distinct representations of similar inputs, and statistical learning, the rapid extraction of regularities across multiple inputs, have both been linked to hippocampal processing. It has been proposed that there may be functional differentiation within the hippocampus, such that the trisynaptic pathway (entorhinal cortex > dentate gyrus > CA3 > CA1) supports pattern separation, whereas the monosynaptic pathway (entorhinal cortex > CA1) supports statistical learning. To test this hypothesis, we investigated the behavioral expression of these two processes in BL, an individual with highly selective bilateral lesions in the dentate gyrus that presumably disrupts the trisynaptic pathway. We tested pattern …

Increased Top-Down Control Of Emotions During Symptom Provocation Working Memory Tasks Following A Rct Of Alpha-Down Neurofeedback In Ptsd., Saurabh Bhaskar Shaw, Andrew A Nicholson, Tomas Ros, Sherain Harricharan, Braeden Terpou, Maria Densmore, Jean Theberge, Paul Frewen, Ruth A Lanius

Department of Medicine Publications

BACKGROUND: Posttraumatic stress disorder (PTSD) has been found to be associated with emotion under-modulation from the prefrontal cortex and a breakdown of the top-down control of cognition and emotion. Novel adjunct therapies such as neurofeedback (NFB) have been shown to normalize aberrant neural circuits that underlie PTSD psychopathology at rest. However, little evidence exists for NFB-linked neural improvements under emotionally relevant cognitive load. The current study sought to address this gap by examining the effects of alpha-down NFB in the context of an emotional n-back task.

METHODS: We conducted a 20-week double-blind randomized, sham-controlled trial of alpha-down NFB and collected …

How The Body Remembers: Examining The Default Mode And Sensorimotor Networks During Moral Injury Autobiographical Memory Retrieval In Ptsd., Breanne E Kearney, Braeden A Terpou, Maria Densmore, Saurabh B Shaw, Jean Theberge, Rakesh Jetly, Margaret C Mckinnon, Ruth A Lanius

Department of Medicine Publications

Neural representations of sensory percepts and motor responses constitute key elements of autobiographical memory. However, these representations may remain as unintegrated sensory and motor fragments in traumatic memory, thus contributing toward re-experiencing and reliving symptoms in trauma-related conditions such as post-traumatic stress disorder (PTSD). Here, we investigated the sensorimotor network (SMN) and posterior default mode network (pDMN) using a group independent component analysis (ICA) by examining their functional connectivity during a script-driven memory retrieval paradigm of (potentially) morally injurious events in individuals with PTSD and healthy controls. Moral injury (MI), where an individual acts or fails to act in a …

Homeostatic Normalization Of Alpha Brain Rhythms Within The Default-Mode Network And Reduced Symptoms In Post-Traumatic Stress Disorder Following A Randomized Controlled Trial Of Electroencephalogram Neurofeedback., Andrew A Nicholson, Maria Densmore, Paul A Frewen, Richard W J Neufeld, Jean Theberge, Rakesh Jetly, Ruth A Lanius, Tomas Ros

Department of Medicine Publications

Collective research has identified a key electroencephalogram signature in patients with post-traumatic stress disorder, consisting of abnormally reduced alpha (8-12 Hz) rhythms. We conducted a 20-session, double-blind, randomized controlled trial of alpha desynchronizing neurofeedback in patients with post-traumatic stress disorder over 20 weeks. Our objective was to provide mechanistic evidence underlying potential clinical improvements by examining changes in aberrant post-traumatic stress disorder brain rhythms (namely, alpha oscillations) as a function of neurofeedback treatment. We randomly assigned participants with a primary diagnosis of post-traumatic stress disorder (

Ideal Body Weight And Body Fat Percentage Predict Relative Energy Deficiency In Sport (Red-S) Scores In Collegiate Athletes, Emily Norman

Theses and Dissertations--Nutrition and Food Systems

Background: Low energy availability (LEA) is the underlying cause of Relative Energy Deficiency in Sport (RED-S) which negatively affects athletes' physiological function, health, and performance. RED-S results from inadequate dietary intake to support energy expenditure for daily living, growth, and optimal performance. It occurs in both male and female athletes, with or without disordered eating. However, screening and diagnosis in athletes can be difficult. Objective: This study aims to identify strong predictors of RED-S and assess its prevalence in collegiate male and female athletes. Methods: A total of 270 NCAA athlete test points from mixed sports were evaluated for RED-S …

Unpredictable Needs Are Associated With Lower Expectations Of Repayment, Jessica D. Ayers

Psychological Sciences Faculty Publications and Presentations

Sometimes people help one another expecting to be repaid, while at other times people help without an expectation of repayment. What might underlie this difference in expectations of repayment? We investigate this question in a nationally representative sample of US adults (N = 915), and find that people are more likely to expect repayment when needs are perceived to be more predictable. We then replicate these findings in a new sample of US adults (N = 417), and show that people have higher expectations of repayment when needs are perceived to be more predictable because people assign greater …

Higher Intensity Walking Improves Global Cognition During Inpatient Rehabilitation: A Secondary Analysis Of A Randomized Control Trial, Sue Peters, Keith R Lohse, Tara D Klassen, Teresa Liu-Ambrose, Sean P Dukelow, Mark T Bayley, Michael D Hill, Sepideh Pooyania, Jennifer Yao, Janice J Eng

Physical Therapy Publications

Cognitive deficits are common poststroke. Cognitive rehabilitation is typically used to improve cognitive deficits. It is unknown whether higher doses of exercise to promote motor recovery influence cognitive outcomes. Our recent trial, Determining Optimal Post-Stroke Exercise (DOSE), shows more than double the steps and aerobic minutes can be achieved during inpatient rehabilitation versus usual care, and translates to improved long-term walking outcomes. Thus, the secondary analysis aim was to determine the effect of the DOSE protocol on cognitive outcomes over 1-year poststroke. The DOSE protocol progressively increased step number and aerobic minutes during inpatient stroke rehabilitation over 20 sessions. The …

Implementation Of Increased Physical Therapy Intensity For Improving Walking After Stroke: Walk 'N Watch Protocol For A Multisite Stepped-Wedge Cluster-Randomized Controlled Trial, Sue Peters, Shannon B Lim, Mark T Bayley, Krista Best, Louise A Connell, Hélène Corriveau, Sarah J Donkers, Sean P Dukelow, Tara D Klassen, Marie-Hélène Milot, Brodie M Sakakibara, Lisa Sheehy, Hubert Wong, Jennifer Yao, Janice J Eng

Physical Therapy Publications

RATIONALE: Clinical practice guidelines support structured, progressive protocols for improving walking after stroke. Yet, practice is slow to change, evidenced by the little amount of walking activity in stroke rehabilitation units. Our recent study (n = 75) found that a structured, progressive protocol integrated with typical daily physical therapy improved walking and quality-of-life measures over usual care. Research therapists progressed the intensity of exercise by using heart rate and step counters worn by the participants with stroke during therapy. To have the greatest impact, our next step is to undertake an implementation trial to change practice across stroke units where …

Premotor And Posterior Parietal Cortex Activity Is Increased For Slow, As Well As Fast Walking Poststroke: An Fnirs Study, Shannon B Lim, Sue Peters, Chieh-Ling Yang, Lara A Boyd, Teresa Liu-Ambrose, Janice J Eng

Physical Therapy Publications

Background and Purpose. The ability to change gait speeds is important for interacting with the surrounding environment. Gait speed modulation poststroke is often impaired and is related to decreased walking independence after stroke. Assessment of brain activation during walking at different speeds can provide insight into important regions for facilitating gait recovery. The purpose is to determine: (1) the symmetry of brain activation as individuals increase or decrease their gait speed, (2) the activation levels in frontal to parietal brain regions during walking at different speeds, and (3) the relationship between an individual’s stroke impairment or their ability to modulate …

Perceptions About Human Papillomavirus Vaccine And Oropharyngeal Cancers, And The Role Of Dental Care Providers In Human Papillomavirus Prevention Among Us Adults, Shillpa Naavaal, Christina A. Demopoulos, Abigail Kelly, Eric Tranby, Julie Frantsve-Hawley

Dental Public Health and Policy Publications

Background: The authors examined adults' perceptions about the importance of the human papillomavirus (HPV) vaccine in preventing oropharyngeal cancers and dental care providers' role in HPV prevention and identified associated factors.

Methods: Adults (≥ 18 years) completed a national survey of consumer and patient attitudes, experiences, and behaviors on oral health. Descriptive and multivariable logistic regression models determined associations between perceptions regarding HPV and attitudes toward dental care providers' role and HPV knowledge, HPV vaccine recommendation, and sociodemographic characteristics.

Results: One in 3 adults (32.8%; n = 5,320) said the HPV vaccine was very important, 1 in 2 said it …

The Impacts Of Role Overload And Role Conflict On Physicians' Technology Adoption, Eun Hee Park, Ghiyoung P. Im, Jing Zhang, Young Hwan Lee, Kyung Hee Chun, Young Soon Park

Information Technology & Decision Sciences Faculty Publications

Technology adoption is an important solution for physicians to increase work efficiency, and thus deal with role conflict among their multiple job roles. Prior studies have not investigated how multiple job roles and role conflict influence physicians’ technology adoption intentions. Based on role strain theory and role identity theory, we present a model of physicians’ technology adoption intentions to support their primary (clinical care) versus secondary (teaching or research) job roles. We test the model using surveys with 156 physicians at nine medical schools in Korea. The results of our data analysis largely support our hypotheses. Role overload in each …

An Objective Structured Clinical Examination (Osce) For Pec-Ii And Intrapec Block For Breast Augmentation Surgery, Kaleb Smith

Doctoral Projects

Ultrasound-guided regional anesthesia techniques are valuable tools for anesthesia providers to learn and implement in their practice. Two specific blocks that student registered nurse anesthetists (SRNAs) need to utilize are PECS-II and the Intrapec block for reconstructive breast augmentation and mastectomies. Teaching these blocks to SRNAs in the clinical setting may be difficult as they will be under higher pressure to perform since they will be practicing on live patients. Understanding this stress led to a review of the current Nurse Anesthesia Program (NAP) curriculum at The University of Southern Mississippi (USM) and found a gap in the education, which …
