Telogen Effluvium And Anesthesia Considerations: A Case Report., Elizabeth Johnson-Gray, Samantha A Currier, Hanen Fernandez, Matt Brown, Matthias Franzen

Ambulatory and Primary Care Articles

Telogen effluvium is a form of non-scarring hair loss characterized by premature shedding of hair. Pathophysiologically, telogen effluvium occurs when a significant number of hair follicles prematurely enter the telogen phase, resulting in excessive shedding. The exact mechanism is unclear, but it is believed to involve alterations in the hair follicle's growth cycle, possibly mediated by illness, infection, major surgery, low protein intake, or hormonal changes. Some medications can also be linked to this disease, such as beta blockers, carbamazepine, and vitamin A. When affected hairs are in the resting phase, noticeable hair shedding occurs. Our patient was a 61-year-old …

A Phenomenological Study On The Enabling Role Of Digital Competencies In Heutagogical Learning Contexts, Jennifer Dean

Masters

This study examines how digital competencies contribute to independent learning within heutagogical contexts in higher education.   The research was conducted to address assumptions that digital competence directly enables learner autonomy, despite limited understanding of this empirical relationship in practice.   A qualitative hermeneutic phenomenological approach was employed, using nine semi-structured interviews to explore learners’ lived experiences in digitally mediated environments.   The findings indicate that self-directed learning is primarily driven by intrinsic motivation and often occurs unconsciously.   Digital competencies were found to act as enabling factors by facilitating access, flexibility and engagement, however, their influence on autonomy was context-dependent rather than deterministic. …

Expanding Equity And Innovation In Pharmaceutical Law And Drug Development: Paying Clinical Trial Participants For Their Data, Steve Calandrillo, Bernadette Tosti, Jefferson Smith, Jamison Koeman

Articles

Bringing a drug to market is exceedingly expensive and exposes pharmaceutical manufacturers to significant legal risk. But when companies are successful, their profits make the PowerBall jackpot look like petty cash. Staggering rewards measure in the billions or millions for the firms, CEOs, pharmacies, drug benefit managers, data brokers, and many more actors in the pharmaceutical-to-patient pipeline. The only individuals who don’t get paid handsomely are the clinical trial participants, whose voluntary participation and data helped make those successes possible. It is long past time that we reform the legal and regulatory roadblocks to paying clinical trial participants in the …

Torus Probabilistic Principal Component Analysis, Anahita Nodehi, Mousa Golalizadeh, Mehdi Maadooliat, Claudio Agostinelli

Mathematical and Statistical Science Faculty Research and Publications

Analyzing data in non-Euclidean spaces, such as bioinformatics, biology, and geology, where variables represent directions or angles, poses unique challenges. This type of data is known as circular data in univariate cases and can be termed spherical or toroidal in multivariate contexts. In this paper, we introduce a novel extension of probabilistic principal component analysis (PPCA) designed for toroidal (or torus) data, termed torus probabilistic PCA (TPPCA). We provide detailed algorithms for implementing TPPCA and demonstrate its applicability to torus data. To assess the efficacy of TPPCA, we perform comparative analyses using a simulation study and three real datasets. Our …

Objective: To examine associations of serum imidazole propionate (ImP), histidine, and their ratio with incident type 2 diabetes (T2D) and related dietary and gut microbial factors in U.S. Hispanic/Latino people.

Research design and methods: In the Hispanic Community Health Study/Study of Latinos, we evaluated serum ImP, histidine, and ImP-to-histidine ratio at baseline (2008-2011) and their cross-sectional associations with dietary intake and prospective associations with incident T2D over ∼12 years (n = 4,632). In a subsample with gut microbiota data during a follow-up visit (2016-2018), we examined gut microbial species associated with serum ImP and their potential interactions with dietary intake. …

High-Impact Chronic Pain And Cognitive Decline Among Mexicans Aged 60 And Older From 2012 To 2018, Rafael Samper-Ternent

Faculty, Staff and Student Publications

Pain is associated with cognitive decline, but prior research has not considered differences between high- and low-impact chronic pain or low-and middle-income countries, such as Mexico. Our objective was to evaluate the association between high-impact chronic pain and cognitive decline among older adults in Mexico. We used data from the 2012-2018 Mexican Health and Aging Study (MHAS), a nationally representative study of older Mexican adults (60+). Pain, measured at each wave, was categorized as high-impact chronic pain (pain that limits daily activities), low-impact chronic pain (pain that did not limit daily activities), and no chronic pain. Cognition was measured at …

Lessons From Mysticism For Healthcare Providers: Health Care As A Space For Intersubjective Encounters Of Care, Micaela Plantinga, Alexandre A. Martins

Theology Faculty Research and Publications

Society’s deep divisions, fueled by individualism, competition, consumerism, rigid ideologies, and limited dialogue, have impacted health care, leading to weakened connections between providers and patients. In the U.S., heavy reliance on medical technology and the rise of AI have further eroded these intersubjective bonds, reducing empathetic engagement in care. To address this challenge, the paper explores insights from Christian mystics Saint Teresa of Avila and Edith Stein. Teresa’s teachings on self-examination and humility, despite her life as a cloistered nun, influenced both her religious order and the broader Church. Meanwhile, Stein’s phenomenological approach emphasized empathy and "suffering with" others, viewing …

The brain vasculature supplies neurons with glucose and oxygen, but little is known about how vascular plasticity contributes to brain function. Using longitudinal in vivo imaging, we report that a substantial proportion of blood vessels in the adult mouse brain sporadically occlude and regress. Their regression proceeds through sequential stages of blood-flow occlusion, endothelial cell collapse, relocation or loss of pericytes, and retraction of glial endfeet. Regressing vessels are found to be widespread in mouse, monkey and human brains. We further reveal that blood vessel regression cause a reduction of neuronal activity due to a dysfunction in mitochondrial metabolism and …

Background Cardiovascular-related morbidity and mortality among young adults are rising, and disparities between young Black and White women are immense. Health behaviors including physical activity and diet are essential for optimal cardiovascular health. Psychosocial factors, such as racism, perceived stress, and lack of social support, contribute to racial inequities in cardiovascular disease, which were further exacerbated by the COVID-19 pandemic. The proposed study aims to assess the influence of racism-related stress and other social determinants of health, including social connectedness, on quality of life and cardiovascular-related health behaviors. Methods This is a concurrent, triangulation, mixed-methods study combining survey data on …

The Impact Of Household Dysfunction On Dating Violence Perpetration Among Adolescents In The United States: A Scoping Review, Nivedhitha Parthasarathy, Christine M Markham

Faculty, Staff and Student Publications

Adverse childhood experiences, such as household dysfunction (HD), play a central role in how adolescents establish, experience, and navigate the challenges of relationship formation, maintenance, and dissolution. HD exposures have been independently associated with dating violence (DV) perpetration in both adolescents and adults. However, research examining the association between the concurrent effect of HD on DV perpetration, especially among adolescents remains scarce. Thus, we conducted a scoping review to accumulate and summarize existing research regarding the impact of HD on DV perpetration among adolescents aged 10 to 17 years in the United States. We used three electronic databases, Medline (Ovid), …

The Impact Of Instructional School Design: The 6–12 School Model As A Strategic Response To Increase Black Boys Self-Efficacy, Xavier E. Edwards

Education Doctoral

This dissertation investigated the impact of the 6–12 instructional school design on the self-efficacy of Black boys, utilizing the theoretical frameworks of Bandura's self-efficacy model and Yosso's community cultural wealth model. The research explored how this specialized school structure supports Black boys' academic achievement, aspirations, and resilience—addressing longstanding disparities in educational and social outcomes. Through qualitative interviews with Black male alumni of 6–12 school models, the study identified factors within the design that positively influence self-efficacy both within and beyond the classroom. Findings indicated that sustained relationships with supportive teachers, a keen sense of brotherhood among peers, and consistent engagement …

Struggling Access To Justice Through Mediation In Bangladesh: Headway Lessons From Australia, Jamila A. Chowdhury, Mehnaz Siddiqui

The Indonesian Journal of Socio-Legal Studies

Enormous case backlog and protracted delays in courts are hindering access to justice in Bangladesh. Consequently, an initiative to provide quick and low-cost consensual justice through mediation was first initiated in the family courts of Bangladesh in the year 2000. However, although after an initial success, the system has been struggling over the decades. While contemporary research has identified various constraints causing such meager disposal of cases in family courts, using expert interviews of family court judges and relevant literature review on Australian family courts, this Chapter reiterates such constraints to generate relevant headway lessons from Australia that has excelled …

No One Acts Alone-Unravelling The Compositional Influences Of Organic Compounds In Offshore Produced Water On Zebrafish Embryotoxicity, Lisbet Sørensen, Paul Mccormack, Paul Sutton, Julia Farkas, Sonnich Meier, Steven J. Rowland, Trond Nordtug, Bjørn Henrik Hansen

School of Geography, Earth and Environmental Sciences

Offshore produced water (PW) is one of the largest and most chemically complex effluents of waste directly and intentionally discharged into the marine environment. Although it is well known that PW can be severely toxic to marine organisms, the mechanisms of toxicity remain poorly understood, contributed by the lack of comprehensive chemical characterization of the PW. In this study, we applied elements of effects-directed analysis with the aim to identify organic chemical drivers of toxicity in PW towards fish early life stages. A solvent extract of a PW was fractioned based on compound functionality and chemically characterized by a concert …

Information Production By Institutions And Information Extraction By Underwriters In Hybrid Ipo Auctions, Thomas J. Chemmanur, Pengfei Ma, Qianqian Yu

Research Collection Lee Kong Chian School Of Business

We analyze the informational properties of hybrid IPO auctions using a large and unique database of institutional bids from Chinese IPO auctions. We find strong evidence of information production by institutions about the intrinsic values of IPO firms and of underwriters extracting and using this information in IPO pricing. The IPO offer price is more sensitive to bids from institutions able to produce more precise information. In particular, the offer price is more sensitive to bids from domestic institutions, compared to bids from foreign institutions who likely have less knowledge or experience about the Chinese firms and financial market due …

The Impact Of Attendance-Based Parent Workshops On Student Absenteeism In The Primary Grades, Kelli Ruby

Doctor of Education (EdD)

Absenteeism is on the rise in schools, significantly impacting young students. Despite ongoing interventions, chronic absenteeism continues to grow in primary grades, creating potential deficits in learning, health, and life outcomes. Although chronic absenteeism has been extensively researched, lack of clarity exists about the most effective methods to improve student attendance.

Research has indicated connecting families with schools can positively intervene in absenteeism. The purpose of this study was to determine how parents’ participation in attendance-based workshops affects their perceptions of the value of attendance in primary grades. Due to the complexity of absenteeism, the study employed Bronfenbrenner’s (2001) bioecological …
