Faculty, Staff and Student Publications

Background: Liver diseases pose significant health challenges, underscoring the importance of understanding liver regeneration mechanisms. Systemic adipose tissue is thought to be a primary source of lipids and energy during this process; however, empirical data on the effects of adipose tissue deficiency are limited. This study investigates the role of adipose tissue in liver regeneration, focusing on transient regeneration-associated steatosis (TRAS) and hepatocyte proliferation using a Seipin knockout mouse model that mimics severe human lipodystrophy. Additionally, the study explores therapeutic strategies through adipose tissue transplantation.

Methods: Male Seipin knockout (Seipin-/-) and wild-type (WT) mice underwent 2/3 partial hepatectomy (PHx). Liver …

The Metabolic Basis Of Cancer-Related Fatigue, Robert Dantzer, Brandon Chelette, Elisabeth G Vichaya, A Phillip West, Aaron Grossberg

Faculty, Staff and Student Publications

Although we are all familiar with the sensation of fatigue, there are still profound divergences on what it represents and its mechanisms. Fatigue can take various forms depending on the condition in which it develops. Cancer-related fatigue is considered a symptom of exhaustion that is often present at the time of diagnosis, increases in intensity during cancer therapy, and does not always recede after completion of treatment. It is usually attributed to the inflammation induced by damage-associated molecular patterns released by tumor cells during cancer progression and in response to its treatment. In this review, we argue that it is …

Relationship Between Parental Neglect, Socioeconomic Status, And Aggression In Adolescents, Chemarin Eve Boyd

Walden Dissertations and Doctoral Studies

Aggressive behavior among adolescents poses significant challenges for families, educators, and communities, often stemming from complex interactions between parental behavior and environmental factors. This quantitative nonexperimental study examined the relationship between parental neglect, socioeconomic status (SES), and adolescent aggression, guided by the parental acceptance-rejection theory. Data were collected from 250 parents of adolescents age 12-18 divided into two groups: those reporting no to low levels of aggression and those reporting moderate to high levels. Binary logistic regression was employed to predict the likelihood of adolescent aggression based on parental neglect (categorical) and SES (scale). The results demonstrated that parental neglect …

Risk Factors For Peripheral Artery Disease-Related Amputations Among Black Americans, Darnell L. Blake

Walden Dissertations and Doctoral Studies

Evidence suggests that Black Americans (BAs) are at a significantly higher risk of peripheral artery disease (PAD)-related amputations. This study aimed to examine risk factors for non-traumatic lower extremity amputation (NTLEA) among BAs with PAD addressing a significant knowledge gap regarding racial disparities in PAD outcomes. Grounded in Bandura's social cognitive theory, which posits the interplay among personal factors, environmental influences, and behavior, this study examines how age, gender, income, and comorbidities like cardiovascular disease, kidney disease, and diabetes influence NTLEA across various insurance types (private, Medicaid, Medicare, self-pay). This quantitative cross-sectional study used the 2020 National Inpatient Sample, 1% …

BACKGROUND: Despite the existence of institutional protocols, liver transplant centers often have variability in early immunosuppression practices. We aimed to measure within-center variability in early immunosuppression after pediatric liver transplant (LT) and examine its association with one-year outcomes.

METHODS: We analyzed pediatric LTs from 2013 to 2018 in the United Network for Organ Sharing registry, with data aggregated by center. We categorized induction regimen as corticosteroids only vs. T-cell depleting antibody vs. non-T-cell depleting antibody. Primary exposures were coefficient of immunosuppression variability (CIV) in (1) induction and (2) mycophenolate mofetil (MMF) use. Primary outcomes were one-year graft survival, patient survival, …

Spectrum Of Venous Thromboembolism In Adult Patients With Ulcerative Colitis In Pakistan: A Single Center Retrospective Study, Masood Muhammad Karim, , Hafsa Shaikh, Faisal Wasim Ismail

Department of Medicine

Background: Patients with inflammatory bowel disease are at a 2-8-fold higher risk of developing venous thromboembolism (VTE) as compared to the general population. Although the exact pathogenesis is unclear, the literature suggests that increased risk of thromboembolic events in such patients occurs as a result of increased coagulation factors, inflammatory cytokines, and reduction in anticoagulants leading to a prothrombotic state.
Aim: To assess the prevalence, risk factors, management, and outcome of ulcerative colitis (UC) patients who develop VTE.
Methods: This was a retrospective chart review done in The Gastroenterology Department of The Aga Khan University Hospital. Data was collected from …

Leptin Receptor Neurons In The Dorsomedial Hypothalamus Require Distinct Neuronal Subsets For Thermogenesis And Weight Loss, Marie Francois, Laura Kaiser, Yanlin He, Yong Xu, J Michael Salbaum, Sangho Yu, Christopher D Morrison, Hans-Rudolf Berthoud, Heike Münzberg

Children’s Nutrition Research Center Staff Publications

The dorsomedial hypothalamus (DMH) receives inputs from the preoptic area (POA), where ambient temperature mediates physiological adaptations of energy expenditure and food intake. Warm-activated POA neurons suppress energy expenditure via brown adipose tissue (BAT) projecting neurons in the dorsomedial hypothalamus/dorsal hypothalamic area (dDMH/DHA). Our earlier work identified leptin receptor (Lepr)-expressing, BAT-projecting dDMH/DHA neurons that mediate metabolic leptin effects. Yet, the neurotransmitter (glutamate or GABA) used by dDMH/DHALepr neurons remains unexplored and was investigated in this study using mice. We report that dDMH/DHALepr neurons represent equally glutamatergic and GABAergic neurons. Surprisingly, chemogenetic activation of glutamatergic and/or GABAergic dDMH/DHA neurons were capable …

Let’S Talk About Quality: How Equitable Funding And Program Structure Impact Academic And Social Outcomes In Supplemental Education Programs, Inayah Ansari

Dissertations, Theses, and Capstone Projects

Although many studies have highlighted how high–quality supplemental education programs (early childhood education and after-school programs) help children and adolescents reach developmental milestones faster, very few studies focus on how programs are structured to create the quality that produces positive outcomes. In this paper, I define quality as equitable funding and program structure and interrogate how this conception of quality determines cognitive and social-emotional benefits, particularly for programs in New York City. Using fiscal data and study reviews, I illuminated the impact of budget cuts on programs and the importance of funding. Using a thematic analysis of six interviews conducted …

Characterizing Phosphorus Removal And Recovery Performance Of A 3d Printed Iron-Embedded Polylactic Acid Composite, Colin B. Wilson, Anthony J. Parolari, Andrew Hiestand, Brooke K. Mayer, Allison Murray

Civil and Environmental Engineering Faculty Research and Publications

Green infrastructure (GI) has been heralded as a solution for reducing phosphorus (P) pollution through increasing stormwater runoff infiltration and improving water quality. Despite its global implementation, GI struggles to improve the effluent water quality discharged from these systems consistently. This research evaluates the P removal performance and recovery potential of iron-embedded polylactic acid (PLA) composites through a novel application of three-dimensional (3D) printed representative unit cells (RUC) that could be used to improve effluent quality in GI. The RUC required chemical oxidation to convert the embedded iron to hematite (Fe₂⁢O₃) to facilitate P adsorption. Batch …

Pain Is Modulated Differently Between Females With And Without Patellofemoral Pain: Factors Related To Sensitization, Kemery J. Sigmund, Marie K. Hoeger Bement, Wendy E. Huddleston, Kyle T. Ebersole, Jennifer E. Earl-Boehm

Physical Therapy Faculty Research and Publications

Context

Patellofemoral pain (PFP) has poor long-term recovery outcomes. Central sensitization describes central nervous system changes altering pain modulation, which can complicate recovery (poorer prognosis and worse function). Signs of central sensitization include amplified pain facilitation, pain hypersensitivity, and impaired pain inhibition, which can be measured with temporal summation of pain (TSP), pressure pain thresholds (PPTs), and conditioned pain modulation (CPM), respectively. Sex differences exist for these test responses, but female-only PFP investigations of sensitization are uncommon. Understanding pain modulation in females with PFP could improve treatment protocols.

Objective

To determine whether females with PFP exhibit signs of central sensitization …

Psychology Faculty Research and Publications

Background

Latina mothers have been especially affected by the pandemic and historically exhibit high rates of depression and anxiety. However, few longitudinal studies have assessed the effect of the pandemic on this vulnerable population. We hypothesized that COVID-19-related stressors would associate with psychological distress among Latina mothers across the first year of the pandemic.

Methods

We investigated COVID-19-related impact, stigma, and fears across two critical time points and changes in these measures in relation to changes in maternal anxiety and depression among mothers of Mexican descent living in Southern California (n=152). Surveys were administered within 5–16 weeks of …

A Model For Advocacy: Advancing Policy Change In Support For Patients With Medicaid, Betsy J. Becker, Jenae Pope

Posters and Presentations: Physical Therapy

There are differences in access and utilization of care for patients with Medicaid. When patients cannot access timely therapeutic care, the resulting outcomes are often poor. Because a major limiting factor in accessing services is insurance type, investigating optimal coverage practices is an important first step in advocating for change. This abstract reports on Phase One of a larger collaboration with state professional associations for physical therapy (PT), occupational therapy (OT), and speech-language pathology (SLP) to present a model that describes Medicaid authorization services for PT, OT, and SLP, serving as a guide for policy change.

We collaborated with the …

Beyond Traditional Body Composition Metrics: Load-Capacity Indices Emerge As Predictors Of Cardiometabolic Outcomes—A Systematic Review And Meta-Analysis, Zhongyang Guan, Marianna Minnetti, Steven B. Heymsfield, Eleonora Poggiogalle, Carla M. Prado, Marc Sim, Blossom C.M. Stephan, Jonathan C.K. Wells, Lorenzo M. Donini, Mario Siervo

Research outputs 2022 to 2026

The adaptive and independent interrelationships between different body composition components have been identified as crucial determinants of disease risk. On the basis of this concept, the load-capacity model of body composition, which utilizes measurements obtained through nonanthropometric techniques such as dual-energy X-ray absorptiometry, was proposed. This model is typically operationalized as the ratio of metabolic load (adipose mass) to metabolic capacity (lean mass). In recent years, a series of load-capacity indices (LCIs) have been utilized to identify abnormal body composition phenotypes such as sarcopenic obesity (SO) and to predict the risk of metabolic, cardiovascular, and cognitive disorders. In this review, …

Bowel Emergencies In Patients With Cancer, Hannah Hughes, Ankush Jajodia, Philippe Soyer, Vincent Mellnick, Michael N Patlas

2020-Current year OA Pubs

Cancer is the second most common cause of death worldwide. Bowel emergencies in patients with cancer are becoming increasingly more prevalent due to advances in cancer therapy and longer overall patient survival. When these patients present acutely, they are often frail and may have pre-existing co-morbidities. This article discusses the imaging features of bowel emergencies commonly encountered in oncological patients in clinical practice. These include chemotherapy related colitis, neutropenia enterocolitis and typhlitis, toxic megacolon, bowel perforation, malignant bowel obstruction and gastrointestinal haemorrhage. The radiologist plays a key role in identifying these oncological emergencies and guiding further management.

Obesity is a growing global health epidemic with limited orally administered therapeutics. Serotonin (5-HT) is one neurotransmitter which remains an excellent target for new weight-loss therapies, but a gap remains in understanding the mechanisms involved in 5-HT produced in the dorsal Raphe nucleus (DRN) and its involvement in meal initiation. Using an optogenetic feeding paradigm, we showed that the 5-HTDRN→arcuate nucleus (ARH) circuit plays a role in meal initiation. Incorporating electrophysiology and ChannelRhodopsin-2-Assisted Circuit Mapping, we demonstrated that 5-HTDRN neurons receive inhibitory input partially from GABAergic neurons in the DRN, and the 5-HT response can be enhanced by hunger. Additionally, …

The Perspectives Of Play Advocates On Children’S Unstructured Play In Turkey, Bengi Sullu

Dissertations, Theses, and Capstone Projects

The Convention on the Rights of the Child has established children’s rights to non- discrimination, development, participation and the observance of their best interests. With this recognition, there has been a growing global interest in acknowledging play as a right. Yet unstructured play, in which children can choose when, where and how to play, with control over their play, has not received the same attention, support and investment as organized, structured play (UNCRC General Comment 17, 2013). The way adults perceive and support play shapes the play opportunities that are available to children (Bianquin, 2018; Göl-Güven, 2017). Additionally, institutions and …

Characterizing The Nutrition-Gut Microbiome-Host Physiology Axis To Examine Flexibility In A Fruit-Specialist Primate, Nina Beeby

Dissertations, Theses, and Capstone Projects

Nutrition and, increasingly, microbiota are recognized in shaping all aspects of animal behavioral ecology and physiology. Since diet and nutrition shape not only animal physiology but also gut microbiota, and these microbiota serve as suppliers of and competitors to host nutrition, this raises questions of how these complex nutritional and microbial environments synergistically affect animal physiology. Examining this nutrition-gut microbiome-host physiology axis has immense potential to unveil how these intricate relationships contribute to animals’ responses to environmental change at multiple scales. Most of what we know about primate responses to environmental change is based upon studies examining one or few …
