Intravenous Infusion Of Nicotinamide Adenine Dinucleotide (Nad+) Versus Nicotinamide Riboside (Nr): A Retrospective Tolerability Pilot Study In A Real-World Setting, Kirsten Reyna, Greer Heinzen, Nikita Patel, Marie Ritter, Alexandra Siojo, Henry Legere, Rachele Pojednic

Research outputs 2022 to 2026

Background: Nicotinamide adenine dinucleotide (NAD⁺) is a cofactor for NAD⁺-dependent enzymes that regulate DNA repair, cellular metabolism, and immune function. Supplementation with NAD⁺ and its precursors is commonly used to prevent age-related disease and extend healthspan. Commercial clinical and wellness settings increasingly provide intravenous (IV) NAD⁺ and nicotinamide riboside (NR) despite limited evaluation of safety and effectiveness. These considerations are important, as NAD⁺ and its precursors differ in reported side effects, cellular uptake, and metabolism. This study sought to compare commercially administered NAD⁺ IV and NR IV in humans by evaluating infusion …

Transforming The Public Plate: A Menu Of Options For Public Food Procurement That Nourishes People, Place And Planet, Leah Galvin, Emma-Kate Rose, Stephanie Godrich, Dheepa Jeyapalan, Joanna Horton

Research outputs 2022 to 2026

Public food procurement stands as one of the most powerful, yet chronically underutilised, policy levers available to Australian governments. Every day, publicly funded institutions – hospitals, residential aged care facilities, long day care, prisons, schools, defence facilities and community food programs – purchase and serve food to millions of Australians. These are not simply transactions. Collectively, these purchasing decisions shape production systems, supply chains, diets, livelihoods and environmental outcomes. They determine who thrives within our food system and who is left behind. Transforming the Public Plate is an Australian first. It provides the most comprehensive national picture to date of …

Barriers And Facilitators To Recruiting Older Adult Care Homeresidents Into Clinical Trials Of Medicines And Vaccines: A Scoping Review, Selvarani Subbarayan, Imogen A. Smith-Dodd, Gabriel Nicolson, Jennifer K. Burton, Janet T. Scott, Seshadri S. Vasan, Susan D. Shenkin, Roy L. Soiza, The Watch Consortium

Research outputs 2022 to 2026

Introduction: Excluding Care Home (CH) residents from clinical trials of medicines and vaccines has led to an evidence gap. Findings from younger adults may not be generalisable to CH residents with frailty and dementia. Therefore, it is essential to evaluate pharmacological treatments directly in CH residents to assess their safety and efficacy.

Methods: As part of the Widening Access to Trials in Care Homes project, we conducted a scoping review using Joanna Briggs Institute methodology to identify barriers and facilitators to recruiting CH residents into clinical trials of medicinal products. We searched EMBASE, MEDLINE, PsycINFO, CINAHL, and the Cochrane Library …

Embracing Vulnerability And Evolving Through Trauma: Teacher Educators’ Collaborative Autoethnographic Reflections, Christina Gray, Lambert

Research outputs 2022 to 2026

This collaborative autoethnography examines how two university-based teacher educators navigated personal trauma while continuing their academic and caregiving work. Using narrative portraits, the study explores how collaborative storytelling enabled the authors to embrace vulnerability, surface hidden experiences, and make sense of trauma within the normative and relational conditions of academic professionalism. Analysis of the narratives highlights three interrelated mechanisms that supported wellbeing amidst trauma: the ongoing negotiation of teacher identity, the capacity to accept help and relational support, and intentional self-care through reflective practice. Rather than positioning recovery as linear or complete, the study illuminates how educators may continue to …

Thermoregulation And Associated Disorders: 3pm-Guided Holistic Approach Bridging Innovative And Traditional Chinese Medicine, Zhuo Wang, Liu, Yueqiang Xu, Weijie Cao, Youxin Wang, Haifeng Hou, Xiuhua Guo, Olga Golubnitschaja, Wei Wang, Yuguang Du, Suboptimal Health Study Consortium, European Association For Predictive, Preventive, Personalised Medicine

Research outputs 2022 to 2026

Accurately performed thermoregulation is life-important for the human body. Therefore, a relatively narrow temperature range of 36.5–37 °C, which all our biochemical reactions are adapted to, is rigorously kept by the body allowing for the most effective kinetics of all physiological processes. In contrast, feeling inappropriately cold or too hot in the environment with comfortable temperature ranges are symptoms of an altered or even disordered thermoregulation described for a number of syndromes as well as patient cohorts. The rationale of the paper is to contribute to the paradigm shift from reactive to proactive healthcare considering thermoregulation deficits as an important …

I, Cock-A-Doodle-Do: Reclaiming Masculinity Through Queer Joy And Humorous Self-Exploration, Nelson J. Garcia

Graduate Studies Theses and Dissertations 2026

I examine the contemporary norms of masculinity. My research wrestles with ultimately unresolvable stereotypes and imagery influencing current masculine behavior. I unearth queer potential through the physicality and behavior of the stereotypical “man’s man”. I infuse my own queer identity into my studio practice with an emphasis on humor and joy to subvert traditional models of male performance. This process drives self-exploration that allows me to personally respond, react, be directed, and redirected by the interactions between queerness and masculinity. Masculine and queer representations across various media, such as film, music, and television, historically and continuously inform restrictive cultural norms. …

Decreasing Risk Factors For Post-Intensive Care Syndrome Using Nurse-Led Rounds And A Novel Icu Liberation Bundle, Jennifer Kepler, Kenneth Moller

Publications 2026-present

Background: Critically ill patients are more likely to survive today than at any other time in history. As more patients recover from critical illnesses, however, many experience health impairments known as post-intensive care syndrome. The Society of Critical Care Medicine developed the ICU Liberation Bundle to decrease the risk of post-intensive care syndrome.

Problem: An audit of 100 patient charts identified complete ICU Liberation Bundle documentation in only 20% of eligible patient days, highlighting the need for increased consistency in bundle implementation. Since the ICU Liberation Bundle addresses modifiable post-intensive care syndrome risk factors, lack of consistency implementing bundle interventions …

Background: Prebiotics promote growth of beneficial gut bacteria, whereas antibiotics can disrupt the microbial balance, reduce diversity, and potentially cause gut dysbiosis. This investigation aimed to determine whether antibiotic use before, during, or after birth altered the risk of infant allergic disease outcomes within a maternal prebiotic dietary supplementation trial. Methods: Maternal participants were allocated to consume daily prebiotics (galacto-oligosaccharides and fructo-oligosaccharides) or placebo (maltodextrin) powder from 18 to 20 weeks' gestation until 6 months postnatal. All infants had a family history of allergic disease. Maternal and infant antibiotic use was prospectively collected monthly throughout the trial intervention period, and …

Negotiating Relationships With Food, The Body, And Physical Activity: Who Is The Healthiest Of Them All?, Valeria Varea, Victoria Evans, Dawn Penney, Eibhlish O'Hara

Research outputs 2022 to 2026

Healthy eating and regular exercise are things that many people aspire to, mainly for health reasons. However, these practices can be complex given broader societal discourses. This paper aims to critically interrogate the social conditions and discursive formations that underpin everyday exercisers’ relationships with food, the body, and physical activity by using biopower and biopedagogies as a theoretical approach, and healthism as a set of discourses. Photo elicitation interviews with vignettes were conducted with nine participants who were regular exercisers. We constructed three different scenarios from the interview data and the theoretical approach: 1. Anna: A performance-driven, health compliant, private …

Epigenetic changes, in particular DNA methylation, accumulate with age across different tissues, but whether these changes follow consistent patterns across different organs remains poorly understood. Here we show, through a meta-analysis of more than 15,000 human methylation profiles spanning 17 tissues, that aging produces both conserved and tissue-specific epigenetic signatures. We identify systemic shifts in methylation levels, increases in methylation variability, and growing molecular disorder across tissues. Network analysis revealed tightly connected gene clusters that are not modified by beneficial interventions, alongside a more modifiable cluster linked to NAD⁺ metabolism, supporting NAD⁺ as a potential therapeutic target in …

Patients’ And Health Professionals’ Perspectives On Transforming The Burden Of Haemodialysis (Hd) Treatment To An Opportunity: An In-Depth Qualitative Investigation, Haseeba Shouket, Eyal Gringart, Deirdre Drake, Ulrich Steinwandel

Research outputs 2022 to 2026

Most patients with End Stage Kidney Failure (ESKF) in Pakistan must undergo maintenance haemodialysis (HD) to survive. Session duration and the often lifelong nature of this treatment, along with other factors associated with HD, make it difficult to tolerate. This study took a positive psychological perspective and considered that HD sessions’ duration, which has been a major challenge for HD patients, can be turned to an opportunity for patients’ meaningful engagement. Such meaningful engagement can positively transform Pakistani patients’ experience of HD and extend into their lives outside HD. Twenty-four HD patients and six healthcare professionals were interviewed to explore …

Research outputs 2022 to 2026

Prokaryote-prokaryote symbiotic relationships influence interactions within microbial communities, affecting colonization, survival, and organization. Unlike competition, consortium species facilitate growth via metabolite cross-feeding. This study explored interactions between two early human gut colonizers: partially aerotolerant Bifidobacterium spp. and strict anaerobic Bacteroides spp., using omics techniques. Promotion of Bacteroides spp. growth by Bifidobacterium animalis subsp. lactis was demonstrated through co-culture experiments in anaerobic conditions. Metabolomic analysis revealed over 150 unique metabolites present in B. animalis subsp. lactis supernatants are absent in other Bifidobacterium species, including 3-hydroxycapric acid, D-alanyl-D-alanine, 2-isopropylmalic acid, and D-glucose 2-phosphate. These compounds served as nutritional substrates, including carbon and …

Cardiovascular–Kidney–Metabolic Syndrome Through The Lens Of Gut‑Derived Uremic Toxins, Chudan Xu, Matthew Snelson, Francine Z. Marques

Research outputs 2022 to 2026

Cardiovascular–Kidney–Metabolic (CKM) syndrome represents a complex, interconnected cluster of cardiovascular disease, chronic kidney disease, and metabolic disorders such as obesity and type 2 diabetes. These conditions share overlapping metabolic, inflammatory, and vascular pathways, with the gut microbiome increasingly recognised as a key contributor and common underlying risk factor. Uremic toxins, traditionally considered waste products of host and microbial metabolism, are now recognised as active mediators of tissue damage across the CKM spectrum, particularly in the context of impaired renal function. Their production and accumulation are amplified by disrupted intestinal barrier integrity, chronic inflammation, and reduced renal clearance, collectively driving systemic …
