Changes In Patient-Reported Pain Interference After Surgical Treatment Of Painful Lower Extremity Neuromas, Adam Liebendorfer, Esther Ochoa, Christopher J Dy

2020-Current year OA Pubs

PURPOSE: Painful neuromas commonly cause neuropathic pain, in up to 1 in 20 cases of traumatic or iatrogenic nerve injury. Despite the multiple surgical treatment types that reduce pain, no type has been universally accepted.

METHODS: We performed a retrospective cohort study by administering follow-up surveys to all surgical patients treated in our department for lower-extremity neuroma from September 1, 2015, to October 22, 2021, that could be contacted, excluding those with Morton neuroma. In addition to the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PI) questionnaire, survey questions covered the time to pain reduction, use of physical or …

Adapting A Mobile App To Support Patients With Anorexia Nervosa Following Post-Acute Care: Perspectives From Eating Disorder Treatment Center Stakeholders, Anneliese Haas, Agatha A Laboe, Claire G Mcginnis, Marie-Laure Firebaugh, Jillian Shah, Anna M Bardone-Cone, Kathleen M Pike, C Barr Taylor, Denise E Wilfley, Ellen E Fitzsimmons-Craft

2020-Current year OA Pubs

INTRODUCTION: Anorexia nervosa (AN) is a harmful, life-threatening illness. Patients with severe AN often receive acute treatment but, upon discharge, experience high relapse rates. Evidence-based, outpatient treatment following acute care is critical to preventing relapse; however, numerous barriers (e.g., location, financial limitations, low availability of providers) preclude individuals from accessing treatment. mHealth technologies may help to address these barriers, but research on such digital approaches for those with AN is limited. Further, such technologies should be developed with all relevant stakeholder input considered from the outset. As such, the present study aimed to garner feedback from eating disorder (ED) treatment …

Women's Empowerment And Child Nutrition In A Context Of Shifting Livelihoods In Eastern Oromia, Ethiopia, Karah Mechlowitz, Mark J Manary, Et Al.

2020-Current year OA Pubs

Agriculture, and particularly livestock and animal source foods, has been closely linked to improvements in human nutrition. Production, income, and women's empowerment improve household food security and child nutritional outcomes in interacting ways. Khat production in Eastern Ethiopia is changing the economic and livelihood landscape for communities that have traditionally relied upon small-scale mixed agriculture and livestock production. How this shifting livelihood landscape and the empowerment of women in these communities are affecting nutritional outcomes has not been investigated. Using cross-sectional data collected during formative research for the Campylobacter Genomics and Environmental Enteric Dysfunction (CAGED) project, we developed models to …

Assessment Of Cochlear Synaptopathy By Electrocochleography To Low Frequencies In A Preclinical Model And Human Subjects, Raymond A Haggerty, Kendall A Hutson, William J Riggs, Kevin D Brown, Harold C Pillsbury, Oliver F Adunka, Craig A Buchman, Douglas C Fitzpatrick

2020-Current year OA Pubs

Cochlear synaptopathy is the loss of synapses between the inner hair cells and the auditory nerve despite survival of sensory hair cells. The findings of extensive cochlear synaptopathy in animals after moderate noise exposures challenged the long-held view that hair cells are the cochlear elements most sensitive to insults that lead to hearing loss. However, cochlear synaptopathy has been difficult to identify in humans. We applied novel algorithms to determine hair cell and neural contributions to electrocochleographic (ECochG) recordings from the round window of animal and human subjects. Gerbils with normal hearing provided training and test sets for a deep …

Caregiver Perspectives On The Continued Impact Of The Covid-19 Pandemic On Children With Intellectual/Developmental Disabilities, R A Northrup, E Jones, V Singh, C Holingue, M Meck, C A Gurnett, M Van Stone, L G Kalb

2020-Current year OA Pubs

The COVID-19 pandemic has significantly impacted caregivers, especially those raising a child with an intellectual/developmental disability (IDD). While research has shown substantial disruption to the family, school, and occupational lives of the IDD community, little is known about the long-term impacts of COVID-19. To address this question, 249 caregivers were surveyed via an online questionnaire, between April and August of 2022 (more than 2 years into the pandemic) about potential impacts of the COVID-19 pandemic on their child's access to health- and school-based therapeutic services, caregiver mental health, and family life. The majority of caregivers reported disruptions in access to …

Proteins In Tumor-Derived Plasma Extracellular Vesicles Indicate Tumor Origin, Meltem Barlin, Petra Erdmann-Gilmore, Jacqueline L Mudd, Qiang Zhang, Robert W Seymour, Zhanfang Guo, Julia R Miessner, S Peter Goedegebuure, Ye Bi, Omar A Osorio, Jennifer Alexander-Brett, Shunqiang Li, Cynthia X Ma, Ryan C Fields, R Reid Townsend, Jason M Held

Cancer-derived extracellular vesicles (EVs) promote tumorigenesis, premetastatic niche formation, and metastasis via their protein cargo. However, the proteins packaged by patient tumors into EVs cannot be determined in vivo because of the presence of EVs derived from other tissues. We therefore developed a cross-species proteomic method to quantify the human tumor-derived proteome of plasma EVs produced by patient-derived xenografts of four cancer types. Proteomic profiling revealed individualized packaging of novel protein cargo, and machine learning accurately classified the type of the underlying tumor.

Higher Education’S Effect On Retention: Exploring The Experiences Of Cps Caseworkers, Alisa S. Wright

Electronic Theses and Dissertations

This qualitative research study was an exploration of Child Protective Services (CPS) frontline caseworkers' experiences. The problem investigated was the high number of caseworkers who lacked the knowledge and skills necessary to do their job and the constant turnover of workers within the agency. Although previous researchers have explored many factors that cause caseworker turnover, the research has not focused much on the caseworkers’ perspective. Therefore, this qualitative study explored CPS caseworkers’ opinions and experiences using virtual semistructured interviews. The study specifically focused on the impact that education and training has on job performance and turnover. The study population was …

Down Syndrome And Alzheimer's Disease: A Scoping Review Of Functional Performance And Fall Risk, Selena E Washington, Emily Cler, Cameron Lowery, Susan L Stark

2020-Current year OA Pubs

INTRODUCTION: Alzheimer's disease (AD) occurs in aging adults with Down syndrome (DS) at a higher prevalence and an earlier age than in typical aging adults. As with the general aging adult population, there is an urgent need to understand the preclinical and early phases of AD progression in the adult population with DS. The aim of this scoping review was to synthesize the current state of the evidence and identify gaps in the literature regarding functional activity performance and falls and their significance to disease staging (i.e., mild, moderate, and severe defined staging criteria) in relation to Alzheimer's disease and …

Impact Of Early Pericardial Fluid Chymase Activation After Cardiac Surgery, Brittany Butts, Lee A Goeddel, Jingyi Zheng, Betty Pat, Pamela Powell, James Mobley, Sarfaraz Ahmad, Chad Steele, David Mcgiffin, James E Davies, James F George, Spencer J Melby, Carlos M Ferrario, Louis J Dell'italia

2020-Current year OA Pubs

INTRODUCTION: Chymase is a highly destructive serine protease rapidly neutralized in the circulation by protease inhibitors. Here we test whether pericardial fluid (PCF) chymase activation and other inflammatory biomarkers determine intensive care unit length of stay, and explore mechanisms of chymase delivery by extracellular vesicles to the heart.

METHODS: PCF was collected from adult patients (17 on-pump; 13 off-pump) 4 h after cardiac surgery. Extracellular vesicles (EVs) containing chymase were injected into Sprague-Dawley rats to test for their ability to deliver chymase to the heart.

RESULTS: The mean intensive care unit (ICU) stay and mean total length of stay was …

2020-Current year OA Pubs

Despite the fact that sleep deprivation substantially affects the way animals regulate their body temperature, the specific mechanisms behind this phenomenon are not well understood. In both mammals and flies, neural circuits regulating sleep and thermoregulation overlap, suggesting an interdependence that may be relevant for sleep function. To investigate this relationship further, we exposed flies to 12 h of sleep deprivation, or 48 h of sleep fragmentation and evaluated temperature preference in a thermal gradient. Flies exposed to 12 h of sleep deprivation chose warmer temperatures after sleep deprivation. Importantly, sleep fragmentation, which prevents flies from entering deeper stages of …

Feasibility And Acceptability Of Remote Smartphone Cognitive Testing In Frontotemporal Dementia Research, Jack Carson Taylor, Nupur Ghoshal, Et Al.

2020-Current year OA Pubs

INTRODUCTION: Remote smartphone assessments of cognition, speech/language, and motor functioning in frontotemporal dementia (FTD) could enable decentralized clinical trials and improve access to research. We studied the feasibility and acceptability of remote smartphone data collection in FTD research using the ALLFTD Mobile App (ALLFTD-mApp).

METHODS: A diagnostically mixed sample of 214 participants with FTD or from familial FTD kindreds (asymptomatic: CDR®+NACC-FTLD = 0 [

RESULTS: It was feasible for participants to complete the ALLFTD-mApp on their own smartphones. Participants reported high smartphone familiarity, completed ∼ 70% of tasks, and considered the time commitment acceptable (98% of respondents). Greater disease severity …

Glial Regulation Of Critical Period Plasticity, Jacob Starkey, Eric J Horstick, Sarah D Ackerman

2020-Current year OA Pubs

Animal behavior, from simple to complex, is dependent on the faithful wiring of neurons into functional neural circuits. Neural circuits undergo dramatic experience-dependent remodeling during brief developmental windows called critical periods. Environmental experience during critical periods of plasticity produces sustained changes to circuit function and behavior. Precocious critical period closure is linked to autism spectrum disorders, whereas extended synaptic remodeling is thought to underlie circuit dysfunction in schizophrenia. Thus, resolving the mechanisms that instruct critical period timing is important to our understanding of neurodevelopmental disorders. Control of critical period timing is modulated by neuron-intrinsic cues, yet recent data suggest that …

State Medical Boards (SMBs) can take severe disciplinary actions (e.g., license revocation or suspension) against physicians who commit egregious wrongdoing in order to protect the public. However, there is noteworthy variability in the extent to which SMBs impose severe disciplinary action. In this manuscript, we present and synthesize a subset of 11 recommendations based on findings from our team's larger consensus-building project that identified a list of 56 policies and legal provisions SMBs can use to better protect patients from egregious wrongdoing by physicians.

Approach To Vaccinating The Pediatric Solid Organ Transplant Candidate And Recipient, Carol M Kao, Marian G Michaels

2020-Current year OA Pubs

Solid organ transplantation (SOT) candidates and recipients are at increased risk for morbidity and mortality from vaccine-preventable infections. Children are at particular risk given that they may not have completed their primary immunization series at time of transplant or have acquired natural immunity to pathogens from community exposures. Multiple society guidelines exist for vaccination of SOT candidate and recipients, although challenges remain given limited safety and efficacy data available for pediatric SOT recipients, particularly for live-vaccines. After transplant, individual patient nuances regarding exposure risks and net state of immunosuppression will impact timing of immunizations. The purpose of this review is …

Vancomycin is a broad-spectrum antibiotic widely used in cases of suspected sepsis in premature neonates. While appropriate and potentially lifesaving in this setting, early-life antibiotic exposure alters the developing microbiome and is associated with an increased risk of deadly complications, including late-onset sepsis (LOS) and necrotizing enterocolitis (NEC). Recent studies show that neonatal vancomycin treatment disrupts postnatal enteric nervous system (ENS) development in mouse pups, which is in part dependent upon neuroimmune interactions. This suggests that early-life antibiotic exposure could disrupt these interactions in the neonatal gut. Notably, a subset of tissue-resident intestinal macrophages, muscularis macrophages, has been identified as …

The Actin-Bundling Protein, Pls3, Is Part Of The Mechanoresponsive Machinery That Regulates Osteoblast Mineralization, Samantha M Chin, Carmela Unnold-Cofre, Teri Naismith, Silvia Jansen

2020-Current year OA Pubs

Plastin-3 (PLS3) is a calcium-sensitive actin-bundling protein that has recently been linked to the development of childhood-onset osteoporosis. Clinical data suggest that PLS3 mutations lead to a defect in osteoblast function, however the underlying mechanism remains elusive. To investigate the role of PLS3 in bone mineralization, we generated MC3T3-E1 preosteoblast cells that are stably depleted of PLS3. Analysis of osteogenic differentiation of control and PLS3 knockdown (PLS3 KD) cells showed that depletion of PLS3 does not alter the first stage of osteoblast mineralization in which a collagen matrix is deposited, but severely affects the subsequent mineralization of that matrix. During …

Although there are effective evidence-based interventions (EBIs) to prevent, treat and coordinate care for chronic conditions they may not be adopted widely and when adopted, implementation challenges can limit their impact. Implementation strategies are "methods or techniques used to enhance the adoption, implementation, and sustainment of a clinical program or practice". There is some evidence to suggest that to be more effective, strategies should be

Improvement In The Capacity For Activity Versus Improvement In Performance Of Activity In Daily Life During Outpatient Rehabilitation, Catherine E. Lang, Carey L. Holleran, Michael J. Strube, Terry D. Ellis, Caitlin A. Newman, Meghan Fahey, Tamara R. Deangelis, Timothy J. Nordahl, Darcy S. Reisman, Gammon M. Earhart, Keith R. Lohse, Marghuretta D. Bland

2020-Current year OA Pubs

UNLABELLED: We addressed questions about the potential discrepancy between improvements in activity capacity and improvements in activity performance in daily life. We asked whether this discrepancy is: 1. Common in routine, outpatient care, or an artifact of intervention studies? 2. Unique to upper limb (UL) rehabilitation, or is it seen in walking rehabilitation too? 3. Only seen in persons with stroke, or a broader neurorehabilitation problem?

METHODS:: A longitudinal, observational cohort of 156 participants with stroke or Parkinson disease (PD) receiving outpatient rehabilitation at 5 clinics was assessed around admission and monthly during their episode of care. Individual, longitudinal capacity …

Criminality And Inequity Under Canada's Legalization Of Cannabis: A Study Of Vancouver's Downtown Eastside, Stephanie Lake, Margot Young

All Faculty Publications

The origin of this essay reminds us of the importance of interdisciplinary collaboration to the development and assessment of public policy. It also demonstrates the serendipitous beginnings of many interesting inquiries. This collaboration was thus fortuitous: authors Lake and Young met during Lake’s doctoral dissertation defence. Young was on the examining committee. Lake presented a series of epidemiological studies (three of which are summarized below) involving the use of cannabis for therapeutic and harm reduction purposes among marginalized people who use drugs (PWUD) in Vancouver. Young’s lines of questioning involving the legal implications of Lake’s findings spurred the idea to …

Rich Dad, Gay Dad: The Wealth Traps Of Gay Fatherhood, Aloni Erez

All Faculty Publications

While legal and societal progress has enabled gay fathers to form families, there remains a critical blind spot in our understanding of their financial wellbeing. Specifically, there are indications that a wealth gap may exist among gay father households. This article introduces a novel taxonomy of the mechanisms that likely contribute to a wealth gap for these households, including surrogacy and adoption costs, legal recognition expenses, parental leave policies, discrimination in housing and borrowing, and limited support from families of origin. These obstacles reflect the structural features and prejudices that disproportionately affect households led by non-heterosexual fathers. The article highlights …

Of Lock-Breaking And Stock Taking: Ip, Climate Change And The Right To Repair In Canada, Graham Reynolds

All Faculty Publications

This paper argues that Canadian governments have both legal and moral obligations to act to combat climate change. In seeking to fulfill these obligations, Canadian governments should pay particular attention to Canada’s intellectual property (IP) regime. This paper argues that given the centrality of IP to Canada’s economy, a comprehensive review is required in order to determine whether and the extent to which elements of Canada’s IP regime contribute to climate change or impede climate action. To illustrate the need for such a review, this paper will highlight one example of how Canada’s IP regime, as currently structured, impedes the …

Legislated Ableism: Bill C-7 And The Rapid Expansion Of Medical Assistance In Dying In Canada, Isabel Grant

All Faculty Publications

This paper explores the recent expansion of medical assistance in dying to disabled people who are suffering intolerably but are not at the end of their lives. The paper argues that it is impossible to separate suffering caused by an irremediable disability and suffering caused by the impacts of systemic ableism, which include high rates of poverty, social isolation and exclusion for people with disabilities. The paper suggests that this expansion raises constitutional issues under s. 15 and s. 7 of the Charter because it is premised on a view that portrays disability as potentially worse than death and thus …

The Legal Innovation Sandbox, Cristie Ford, Quinn Ashkenazy

All Faculty Publications

"The Legal Innovation Sandbox" examines a novel regulatory approach, called the innovation sandbox, in the context of the legal profession. The paper makes the claim that the “sandbox” regulatory model is in fact better suited to fostering innovation in the legal services arena than it is in the financial technology, or fintech, arena in which the sandbox concept developed. However, any effort to transplant a technique from one context to another needs to be carefully considered. This article is comparative across disciplines – financial regulation and legal services regulation – and across jurisdictions – covering the United Kingdom, the United …

The Transnational Exchange Of Law Through Climate Change Litigation, Natasha Affolder, Godwin Dzah

All Faculty Publications

Climate change litigation continues to bash holes in the view of domestic legal systems as hermetically sealed units. Domestic cases are inspired by litigation elsewhere, actively fostered by transnational advocacy communities, and the decisions themselves are indicative of transjudicial influences and sometimes even dialogue on climate change. This chapter, written in 2021 to reflect the transnationalism of early climate change litigation, takes a close look at practices of transjudicialism in climate change litigation. In so doing, it seeks to disrupt some default patterns of studying the spread of law. By problematizing the practices of ‘finding’ influential climate law cases, measuring …
