Co-Creation Of Global Public Health Interventions Within The Context Of Limited Resources: A Conceptual Qualitative Framework For Modest Co-Creation, Kahabi Isangula, Constance Constance Shumba

School of Nursing & Midwifery, East Africa

Co-creation is increasingly promoted in global public health as a participatory methodology that centres lived experiences, the preferences, and structural realities of those most affected by health interventions. Within human-centred design (HCD), co-creation is typically operationalised through intensive cycles of qualitative inquiry, in-person workshops, facilitation, and iterative prototyping. While these approaches are methodologically robust, they are often resource-intensive and difficult to implement in low- and middle-income countries (LMICs) and other low resource settings, precisely where context-sensitive and equitable intervention design is most needed. Despite this tension, existing literature offers limited guidance on how co-creation can be meaningfully adapted to such …

Background Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has raised global concerns regarding its impact on pregnant women and their infants, particularly across evolving variants. This study aimed to determine if infection during pregnancy increased the risk of adverse maternal, perinatal, neonatal, or postpartum outcomes during pre-Omicron and Omicron periods.

Methods We conducted a prospective cohort study in 10 primarily low- and middle-income countries, comprising public and private maternity hospitals in rural and urban areas. Maternal age and comorbidity adjusted mixed-effects models with country-specific random intercepts were used to estimate relative risks (RRs) comparing participants with and without infection …

The Rpm-1/Phr Signaling Hub Modulates Tau-Induced Neurodegeneration Through Regulation Of Microtubule Stability And Mapk Pathways In C. Elegans, Xinxing Ding

Theses and Dissertations

Neurodegenerative diseases, including Alzheimer's disease and frontotemporal dementia, are characterized by the accumulation of pathological tau proteins and progressive neuronal loss. Although research regarding tau-mediated toxicity is extensive, the specific pathology that determine whether neurons maintain homeostasis or succumb to collapse under tau-induced stress remain incompletely elucidated. A central, yet still insufficiently understood, feature of these diseases is the disruption of the microtubule (MT) cytoskeleton . The PHR protein family is evolutionarily highly conserved; within this family, RPM-1 in C. elegans functions as an intracellular signaling hub that regulates axon development, synapse formation, axon termination, and various microtubule-associated processes. This …

Surgeon Health And Well-Being Initiative: A Survey Of General And Orthopedic Surgery Residents' Reports Of Musculoskeletal Pain., Maryam Mohamed, Grace J Kim, Kristen Conrad-Schnetz, Zhan Yang, Mary Carneval

Ambulatory and Primary Care Articles

Background Musculoskeletal (MSK) pain is a well-known risk among surgeons, resulting from the multifactorial physical demands of the occupation. Because of the demands faced by resident surgeons, many individuals find themselves with sometimes debilitating MSK pain. Although these risks are well documented and there have been proposed solutions, there is little discussion on the role that osteopathic manipulative treatment (OMT) can play in relief of MSK pain over time in this population. Objective The purpose of this study is to determine the prevalence and distribution of MSK pain among general and orthopedic surgery residents at Cleveland Clinic Foundation (CCF). Based …

Telling Their Intensive Stories: Black/African American Intensive Care Unit Nurses And Their Perceived Encounters With Icu Workplace Racism, Sharon M. Butler

Theses & Dissertations

The 2022 American Nurses Association (ANA) study on racism and racial inequality within the nursing profession both acknowledges the presence of racism in nursing and provides evidence of the diverse negative social and psychological effects of racism on minority nurses. Although the 2022 ANA study sets a precedent and shows evidence of racism’s effects across the broader professional nursing workforce, there is limited nursing research literature that offers a focused presentation and understanding of the lived experiences of minority nurses and their personal perceptions of workplace racism. There is also limited nursing research on how workplace racism impacts cultural and …

A Longitudinal Analysis Of Hospital Consumer Evaluation In Virginia, Tulay Akmandor Inac

Health Services Research Dissertations

Suboptimal patient experience signals a need to improve clinical efficacy, patient safety, and healthcare quality. The COVID-19 pandemic intensified hospital resource and staffing demands, reducing hospitals’ capacity to invest in patient experience improvement. Prior studies remain limited because many lack longitudinal structure and organized theoretical models, making temporal inference difficult and weakening analyses of patient experience disparities. To address these limitations, this dissertation incorporates three studies examining patient experience and pandemic-related effects.

In state-level markets comparable to Virginia, limited research has examined longitudinal patient experience trends across regional hospital systems using HCAHPS scores. The first study uses descriptive trend analysis …

EVMS School of Health Professions Theses & Dissertations

Leadership development is increasingly recognized as an essential component of healthcare education, particularly as medical laboratory professionals assume expanded responsibilities involving collaboration, decision-making, systems thinking, and organizational leadership. Despite this need, limited research has explored how leadership develops within graduate medical laboratory science (MLS) programs. This qualitative case study examined leadership development through the lens of Experiential Learning Theory (ELT). Two research questions explored how the program fostered leadership development through students’ professional biographies, leadership questionnaires, final reflection papers, and leadership credos and how leadership reflections demonstrated growth over time. Secondary data from five student cases were analyzed using deductive …

The Association Between Prenatal Nicotine Exposure And Postpartum Depression, Reem Ali Sharaf-Alddin

Health Services Research Dissertations

Postpartum Depression (PPD) is the most common mental health complication of childbirth with 17% of women globally and 13% in the US experience PPD. The pathophysiology of PPD is not yet fully understood, with psycho-social, biological, and environmental factors, interplaying together and predisposing to PPD. One key modifiable risk factor is prenatal exposure to nicotine (PEN) including Active Tobacco Smoking (ATS), Secondhand Smoking (SHS), and Electronic Nicotine Products (ENPs). Several studies investigated the association between prenatal ATS or SHS and PPD, however the findings were inconclusive. There is a lack of studies that assessed the overall PEN, and none of …

Remote Assessment And Management Of Physical Function In Older Adults (Ramp): An International Expert Delphi Process, Jack Dalla Via, Hurst, Elsa Dent, Jackson J. Fyfe, Paul Jansons, Eleanor J. Hayes, Marc Sim, Mylene Aubertin-Leheudre, Alex Barreto De Lima, Lucimere Bohn, Sabine Britting, Fanny Buckinx, Gavin Connolly, Lora Giangregorio, Duarte Henriques-Neto, Jennifer R.A. Jones, Robert Kob, Suzanne N. Morin, Girish N, Lucas B.R. Orssatto, Maria Pearson, Daniel Pinto, Esmee M. Reijnierse, Catherine M. Said, Mohamed Salem, Gary Skinner

Research outputs 2022 to 2026

Background: Remote methods may help older adults improve their physical function, but understanding the perspectives of experts who deliver this care is critical. This modified Delphi process aimed to develop expert consensus on effectiveness, feasibility and implementation of remote assessment and management of physical function in older adults. Methods: This online Delphi process included experts involved in supporting older adults to maintain or improve their health. The Round 1 survey presented 33 Delphi statements assessed using an 11-point Likert scale (0–10; ≥7 indicated agreement). Statements with strong (≥80 %), moderate (50–<80 %) and low (<50 %) agreement were accepted, revised, or rejected, respectively. Revised statements were presented in Round 2, and accepted statements were consolidated into key messages. Results: In total, 108 respondents (67 % female; mean [SD] age 41.4 [10.9] years) from 16 countries (five continents) completed Round 1. Fourteen statements were accepted (88–100 % agreement) and 10 were rejected (8–39 % agreement). The remaining nine statements (52–69 % agreement) were revised, and two new statements were developed for Round 2, which was completed by 89 (82 %) respondents. Five Round 2 statements were accepted (82–93 % agreement). Seven key messages were developed from 19 accepted statements, highlighting that remote care should be accessible to older adults with requisite capabilities, is feasible for older adults and health professionals with adequate support and training, and requires guidelines, policies, and further research to support wider adoption. Conclusions: The findings of this Delphi process can inform the implementation of remote care approaches for assessing and managing physical function in older adults.

Parkinson's Disease: Immunometabolic Control Points Across Neural, Vascular, And Peripheral Systems, Y Narvaez Irizarry Felix, Alondr M. Bermudez Adorno, Boris Ermolinsky, Lilia Kucheryavykh, Mikhail Inyushin

School of Integrative Biological & Chemical Sciences Faculty Publications

Parkinson's disease (PD) is a progressive neurodegenerative disorder most associated with degeneration of dopaminergic neurons in the substantia nigra pars compacta. Increasing clinical and experimental evidence, however, indicates that PD is a multisystem disease in which immune, metabolic, vascular, and peripheral nervous system dysfunction precede and shape motor circuit failure. Nonmotor manifestations, including olfactory impairment, sleep and autonomic disturbances, gastrointestinal dysfunction, and cognitive decline, often arise years before motor diagnosis, highlighting pathogenic mechanisms beyond dopamine deficiency alone. In this review, we synthesize evidence supporting the view that PD represents a disorder of chronic immunometabolic dysregulation rather than isolated neuronal loss. …

Examining Pain Catastrophizing, Mental Toughness, Self-Efficacy, And Perceived Pain In The Performance Of Female Athletes During Their Menstrual Cycle, Carissa R. Martinez

Electronic Theses and Dissertations

Pain is a universal unpleasant or negative experience influenced by physiological, psychological, and environmental factors. Disruption in the neural pathways of pain can affect athletic performance and lead to injury risks. Both negative attributes, such as stress, anxiety, and depression, and positive attributes, such as mental toughness and self-efficacy, contribute to pain perception and catastrophic thinking. The menstrual cycle also plays a critical role in pain catastrophizing, as hormonal fluctuations across different phases may hinder pain perception and performance in female athletes. However, research lacks the inclusion of how these factors impact female athletes. Using a non-experimental quantitative analysis, this …

Leveraging Administrative Health Data To Capture Rare Adverse Drug Reactions: Identifying Pediatric Patients With Trimethoprim-Sulfamethoxazole Acute Respiratory Distress Syndrome., Keith Feldman, Jenna Miller, Katherine Doane, Laura Loftis, James W. Antoon, Kevin J. Downes, Jennifer Goldman

Manuscripts, Articles, Book Chapters and Other Papers

Rare adverse drug reactions (ADRs) are underrecognized and underreported in the electronic medical record (EMR). These events often require clinical review, making systematic identification challenging. The study aim was to develop an approach to prioritize identification and validation of a rare ADR to trimethoprim-sulfamethoxazole causing acute respiratory distress syndrome (TMP-SMX ARDS) across medical institutions. We developed a clinical phenotype based on 2 local TMP-SMX ARDS cases mapped to standardized elements of a national comparative healthcare database (PHIS). We validated identification of TMP-SMX ARDS at scale across medical institutions. A set of scoring criteria was created to prioritize cases and generate …

A Cooking Skills Intervention For Long-Term Weight Loss In Young Adults With Intellectual Disabilities: Rationale And Design For A Randomized Trial., Lauren T. Ptomey, Jessica C. Danon, Delwyn Catley, Richard A. Washburn, Amy Bodde, Francisco J. Diaz, Brian C. Helsel, Anna M. Rice, Joseph R. Sherman, Madison Koester, Walker S. Mckinney Ph.D., Joseph E. Donnelly

Manuscripts, Articles, Book Chapters and Other Papers

Young adults with intellectual disability (ID) are an underserved population with a high prevalence of obesity, obesity-related health conditions, and reduced ability to complete instrumental and basic activities of daily living (I/ADLs). After leaving the structured environment of public school, many young adults with ID spend more time at home or in day programs, begin living more independently, or enter the workforce. These transitions may increase reliance on fast or processed foods and reduce opportunities for physical activity, contributing to accelerated weight gain. Previous research has demonstrated clinically meaningful short- and long-term weight loss (18-24 months) in adults with mild-to-moderate …

The Joint Effect Of Bilingualism And Sleep On Executive Functions Among Children And Adolescents With Attention Deficit/Hyperactivity Disorder (Adhd), Yirou Jiang

Doctoral Dissertations

Attention Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental disorder that significantly impacts cognitive and behavioral functions, leading challenges for individuals across the lifespan. While extensive research has been conducted to understand the connection between executive functioning (EF) and ADHD, research findings related to the contributing factors of bilingualism and sleep still remains inconsistent (Bialystok et al., 2017). Investigating the joint effect between bilingualism and sleep on EF among children and adolescents with ADHD may help further clarify the connection between EF, language, and sleep, and facilitate the development of interventions from the perspective of these protective factors. EF encompasses cognitive processes …

The Relationship Between Depression And Cognitive Proficiency Index Across Biological Sex, Angela N. Ferdinardo

Dissertations

Depression is a widely studied mood disorder, and understanding its effect on cognitive functioning has become an important area of research. While research has examined relationships among depression, working memory, and cognitive deficits, limited research has explored depressive symptoms and cognitive proficiency across biological sex. Depression manifests similarly in men and women, though men are more likely to experience irritability, impulsivity, and anger, while women tend to experience sadness, stress, and sleep disturbances (Johns Hopkins Medicine, 2023). Women are also more likely to seek treatment and cope differently than men. This study examined the relationship between depression and cognitive proficiency …

Physiological, Cognitive, Behavioral, And Perceptual Contributors To Falls Risk Across Middle And Older Adulthood, Jacquelyn Moxey

Rehabilitation Sciences Theses & Dissertations

Falls are multifactorial events influenced by physiological, cognitive, behavioral, and perceptual factors. Although falls prevention research has traditionally focused on older adults and objectively measured physical impairments, less is known about how cognitive performance, physical activity, and perceptions of ability collectively contribute to falls risk vulnerability across middle and older adulthood. This dissertation examined these relationships through three complementary studies.

Study 1 examined associations between cognitive screening performance and physiological falls risk in 315 community-dwelling older adults. Lower global cognitive performance was associated with greater physiological falls risk. Performance on items reflecting attention and visuospatial/executive function demonstrated the strongest domain-level …
