A Novel Interaction Between Extracellular Vimentin And Fibrinogen In Fibrin Formation, Marina Martinez-Vargas, Adrian Cebula, Lisa S Brubaker, Nitin Seshadri, Fong W Lam, Michele Loor, Todd K Rosengart, Andrew Yee, Rolando E Rumbaut, Miguel A Cruz

Faculty, Staff and Students Publications

INTRODUCTION: Thrombosis is frequently manifested in critically ill patients with systemic inflammation, including sepsis and COVID-19. The coagulopathy in systemic inflammation is often associated with increased levels of fibrinogen and D-dimer. Because elevated levels of vimentin have been detected in sepsis, we sought to investigate the relationship between vimentin and the increased fibrin formation potential observed in these patients.

MATERIALS AND METHODS: This hypothesis was examined by using recombinant human vimentin, anti-vimentin antibodies, plasma derived from healthy and critically ill patients, confocal microscopy, co-immunoprecipitation assays, and size exclusion chromatography.

RESULTS: The level of vimentin in plasma derived from critically ill …

Milder Loss Of Insulin-Containing Islets In Individuals With Type 1 Diabetes And Type 2 Diabetes-Associated Tcf7l2 Genetic Variants, Maria J Redondo, Sarah J Richardson, Daniel Perry, Charles G Minard, Alice L J Carr, Todd Brusko, Irina Kusmartseva, Alberto Pugliese, Mark A Atkinson

Faculty, Staff and Students Publications

AIMS/HYPOTHESIS: TCF7L2 variants are the strongest genetic risk factor for type 2 diabetes. In individuals with type 1 diabetes, these variants are associated with a higher C-peptide AUC, a lower glucose AUC during an OGTT, single autoantibody positivity near diagnosis, particularly in individuals older than 12 years of age, and a lower frequency of type 1 diabetes-associated HLA genotypes. Based on initial observations from clinical cohorts, we tested the hypothesis that type 2 diabetes-predisposing TCF7L2 genetic variants are associated with a higher percentage of residual insulin-containing cells (ICI%) in pancreases of donors with type 1 diabetes, by examining genomic data …

Tanshinone Iia Inhibits Cell Viability And Promotes Puma-Mediated Apoptosis Of Oral Squamous Cell Carcinoma, Shuangze Han, Xinfang Yu, Ruirui Wang, Xiaocong Wang, Lulu Liu, Qing Zhao, Rongbo Xie, Ming Li, Zhong Su Zhou

Faculty, Staff and Students Publications

Apoptosis alteration is responsible for tumorigenesis and tumor resistance to therapies. The natural product Tanshinone IIA (Tan IIA) exhibits potent inhibitory effects against various tumors. However, the effect of Tan IIA on apoptosis and its underlying mechanism remains elusive in oral squamous cell carcinoma (OSCC). Here, we demonstrated that Tan IIA dose-dependently suppressed cell viability and colony formation in CAL27, SCC4, and SCC25 cells. Moreover, Tan IIA inhibited Akt activation from inducing Foxo3a dephosphorylation and PUMA-mediated apoptosis. PUMA or Foxo3a knockdown compromised the inhibitory effect of Tan IIA on OSCC cells. Tan IIA administration inhibited CAL27-deprived xenograft tumor growth and …

Statistical Methods For Gwas And The Impact Of Diabetic Medication Adherence On Healthcare Costs, Meida Wang

Dissertations, Master's Theses and Master's Reports

This dissertation includes three Chapters. In Chapter One, we develop a computationally efficient clustering linear combination approach to jointly analyze multiple phenotypes for GWAS. In this paper, based on the existing CLC method and ACAT strategy, we develop the ceCLC method to test association between multiple phenotypes and a genetic variant. In Chapter Two, we develop a novel method called sCLC for association studies of multiple phenotypes and a genetic variant based on GWAS summary statistics. Simulation results show that sCLC can control Type I error rates well and has the highest power in most scenarios. In Chapter Three, we …

Bacteriuria In Older Adults Triggers Confusion In Healthcare Providers: A Mindful Pause To Treat The Worry, Eva M Amenta, Robin L P Jump, Barbara W Trautner

Faculty, Staff and Students Publications

The evidence base for refraining from screening for or treating asymptomatic bacteriuria (ASB) in older adults is strong, but both practices remain prevalent. Clinical confusion over how to respond to a change from baseline, when to order a urinalysis and urine culture, and what to do with a positive urine culture fuels unnecessary antibiotic use for ASB. If the provider can take a mindful pause to apply evidenced-based assessment tools, the resulting increased clarity in how to manage the situation can reduce overtreatment of ASB.

Distinct Temporal Trajectories And Risk Factors For Post-Acute Sequelae Of Sars-Cov-2 Infection, Chen Chen, Sairam Parthasarathy, Jacqueline M Leung, Michelle J Wu, Katherine A Drake, Vanessa K Ridaura, Howard C Zisser, William A Conrad, Victor F Tapson, James N Moy, Christopher R Defilippi, Ivan O Rosas, Bellur S Prabhakar, Mujeeb Basit, Mirella Salvatore, Jerry A Krishnan, Charles C Kim

Twitter Sentiment About The Us Federal Tobacco 21 Law: Mixed Methods Analysis, Page D. Dobbs, Allison Ames Boykin, Nnamdi Chika Ezike, Aaron Myers, Jason B. Colditz, Brian A. Primack

Health, Human Performance and Recreation Faculty Publications and Presentations

Background: On December 20, 2019, the US “Tobacco 21” law raised the minimum legal sales age of tobacco products to 21 years. Initial research suggests that misinformation about Tobacco 21 circulated via news sources on Twitter and that sentiment about the law was associated with particular types of tobacco products and included discussions about other age-related behaviors. However, underlying themes about this sentiment as well as temporal trends leading up to enactment of the law have not been explored.

Objective: This study sought to examine (1) sentiment (pro-, anti-, and neutral policy) about Tobacco 21 on Twitter and (2) volume …

Faculty, Staff and Students Publications

Metformin is the first-line treatment for type 2 diabetes (T2D) in youth but with limited sustained glycemic response. To identify common variants associated with metformin response, we used a genome-wide approach in 506 youth from the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study and examined the relationship between T2D partitioned polygenic scores (pPS), glycemic traits, and metformin response in these youth. Several variants met a suggestive threshold (P < 1 × 10−6), though none including published adult variants reached genome-wide significance. We pursued replication of top nine variants in three cohorts, and rs76195229 in ATRNL1 was associated with worse metformin response in the Metformin Genetics Consortium (n = 7,812), though statistically not being significant after Bonferroni correction (P …

Gastrointestinal Organoids In The Study Of Viral Infections, J Thomas Gebert, Francesca Scribano, Kristen A Engevik, Jacob L Perry, Joseph M Hyser

Faculty, Staff and Students Publications

Viruses are among the most prevalent enteric pathogens. Although virologists historically relied on cell lines and animal models, human intestinal organoids (HIOs) continue to grow in popularity. HIOs are nontransformed, stem cell-derived, ex vivo cell cultures that maintain the cell type diversity of the intestinal epithelium. They offer higher throughput than standard animal models while more accurately mimicking the native tissue of infection than transformed cell lines. Here, we review recent literature that highlights virological advances facilitated by HIOs. We discuss the variations and limitations of HIOs, how HIOs have allowed for the cultivation of previously uncultivatable viruses, and how …

Early Mortality Among Aboriginal And Non-Aboriginal Women Who Had A Preterm Birth In Western Australia: A Population-Based Cohort Study, Helen D. Bailey, Caitlin Gray, Akilew A. Adane, Natalie A. Strobel, Scott W. White, Rhonda Marriott, Gizachew A. Tessema, Carrington C. J. Shepherd, Mary Sharp

Research outputs 2022 to 2026

Background: Having a preterm ( < 37 weeks' gestation) birth may increase a woman's risk of early mortality. Aboriginal and Torres Strait Islander (hereafter Aboriginal) women have higher preterm birth and mortality rates compared with other Australian women. Objectives: We investigated whether a history of having a preterm birth was associated with early mortality in women and whether these associations differed by Aboriginal status. Methods: This retrospective cohort study used population-based perinatal records of women who had a singleton birth between 1980 and 2015 in Western Australia linked to Death Registry data until June 2018. The primary and secondary outcomes were all-cause and cause-specific mortality respectively. After stratification by Aboriginal status, rate differences were calculated, and Cox proportional hazard regression was used to estimate adjusted hazard ratios (HR) and 95 % confidence intervals (CI) for all-cause and cause-specific mortality. Results: There were 20,244 Aboriginal mothers (1349 deaths) and 457,357 non-Aboriginal mothers (7646 deaths) with 8.6 million person-years of follow-up. The all-cause mortality rates for Aboriginal mothers who had preterm births and term births were 529.5 and 344.0 (rate difference 185.5, 95 % CI 135.5, 238.5) per 100,000 person-years respectively. Among non-Aboriginal mothers, the corresponding figures were 125.5 and 88.6 (rate difference 37.0, 95 % CI 29.4, 44.9) per 100,000 person-years. The HR for all-cause mortality for Aboriginal and non-Aboriginal mothers associated with preterm birth were 1.48 (95 % CI 1.32, 1.66) and 1.35 (95 % CI 1.26, 1.44), respectively, compared with term birth. Compared with mothers who had term births, mothers of preterm births had higher relative risks of mortality from diabetes, cardiovascular, digestive and external causes. Conclusions: Both Aboriginal and non-Aboriginal women who had a preterm birth had a moderately increased risk of mortality up to 38 years after the birth, reinforcing the importance of primary prevention and ongoing screening.

Preference For Male Risk Takers Varies With Relationship Context And Health Status But Not Covid Risk, Cyril C. Grueter, Hannah Goodman, Nicolas Fay, Bradley Walker, David Coall

Research outputs 2022 to 2026

Risk taking is more commonly shown by males than females and has a signalling function, serving to advertise one’s intrinsic quality to prospective mates. Previous research has established that male risk takers are judged as more attractive for short-term flings than long-term relationships, but the environmental and socioeconomic context surrounding female preferences for male risk takers has been overlooked. Using a survey instrument, we examined female preferences for male risk takers across 1304 females from 47 countries. We found preferences for physical risk takers to be more pronounced in females with a bisexual orientation and females who scored high on …

Assessing Children To Identify Developmental Coordination Disorder: A Survey Of Occupational Therapists In Australia, Jacqui Hunt, Jill Zwicker, Erin Godecke, Annette Raynor

Research outputs 2022 to 2026

Background: Developmental coordination disorder (DCD), a prevalent neurodevelopmental disorder with motor and psychosocial consequences, can significantly impact children's quality of life. In Australia, most children with diagnosed/suspected DCD have received occupational therapy services, more so than any other health service. As such, occupational therapists are key in identification and treatment and require a sound knowledge of diagnostic criteria and the best evidence for practice. This study explored current occupational therapy services for children with DCD. Areas for development are identified to improve the identification of, and subsequent intervention for, children with DCD. Methods: In this cross-sectional study, an online survey …

Theory-Based Behaviour Change Intervention To Promote Mental Health Help-Seeking Among Older Adults In Australia: Initial Dissemination And Acceptability, Claire Adams, Eyal Gringart, Natalie Strobel

Research outputs 2022 to 2026

Objective: Rates of help-seeking for mental health problems among older adults are low and initiatives to increase help-seeking in older populations are limited. To our knowledge, no interventions have aimed to promote help-seeking among older adults by tapping internal motivations to seek help. In this paper, we describe the development of a theory-based intervention designed to promote mental health help-seeking among older adults in Australia, using an internal motivation paradigm. Methods: The intervention was co-designed through a consultative process with nine key stakeholders who represented five main groups: primary health-care providers, mental health professionals, health-care executives, community organisations and consumers. …

Partly because it is unconscious, managing implicit bias in public health/healthcare remains intractable. Hence, administrators, practitioners, and their students unknowingly discriminate against others especially including socioeconomically disadvantaged people in the US and elsewhere. . . .

Development Of A Scoring Tool For Australian Rural Food Retail Environments, Tracy L. Schumacher, Carissa A. Alderton, Leanne J. Brown, Susan Heaney, Laura Alston, Katherine Kent, Stephanie L. Godrich

Research outputs 2022 to 2026

Current tools scoring the healthiness of food retail outlets do not reflect outlets found in rural locations. This study aimed to adapt pre-existing Australian scoring tools to represent non-metropolitan areas. Rural nutrition experts were identified, and a modified Delphi technique was used to adapt two pre-existing, food-scoring tools in five iterative stages. Stages included identifying all relevant outlets, providing a description and score for each, ensuring consistency between outlet scores and pre-existing, metro-centric tools, and providing instructions for correct use. Six rural nutrition experts were identified and engaged in the modified Delphi technique. The final tool consisted of 12 categories …

Rodriguez, Mavil May Cervo, Anoohya Gandham, Cecilia L. H. Xu, Costas Glavas, Barbora De Courten, Ayse Zengin, Peter R. Ebeling, David Scott

Research outputs 2022 to 2026

Purpose:

Vitamin D supplementation may have non-skeletal health benefits and enhance exercise responsiveness, particularly in those with low vitamin D levels. We determined whether, compared with placebo, vitamin D supplementation taken prior to and during a 12-week exercise program improves physical function, body composition or metabolic health, in overweight and obese older adults with vitamin D deficiency.

Methods:

Fifty overweight or obese older adults (mean ± SD age: 60 ± 6 years; BMI 30.6 ± 5.7 kg/m2) with vitamin D deficiency (25-hydroxyvitamin D [25(OH)D] < 50 nmol/L) were recruited. Participants were randomly allocated to receive either vitamin D3 (4000 IU/day) or matching placebo for 24 weeks. Between weeks 12 and 24, all participants completed multi-modal exercise three days per week while continuing with vitamin D/placebo. Mean changes in physical function (primary outcome: gait speed), body composition and biochemical parameters at weeks 12 and 24 were compared between groups.

Results:

Vitamin D supplementation, with or without exercise, had no effect on gait speed. From baseline …

Research outputs 2022 to 2026

Background:

To date, most countries worldwide have declared that the pandemic of COVID-19 is over, while the WHO has not officially ended the COVID-19 pandemic, and China still insists on the personalized dynamic COVID-free policy. Large-scale nucleic acid testing in Chinese communities and the manual interpretation for SARS-CoV-2 nucleic acid detection results pose a huge challenge for labour, quality and turnaround time (TAT) requirements. To solve this specific issue while increase the efficiency and accuracy of interpretation, we created an autoverification and guidance system (AGS) that can automatically interpret and report the COVID-19 reverse transcriptase-polymerase chain reaction (RT-PCR) results relaying …

Spore-Forming Clostridium (Clostridioides) Difficile In Wastewater Treatment Plants In Western Australia, Jessica M. Chisholm, Papanin Putsathit, Thomas V. Riley, Su-Chen Lim

Research outputs 2022 to 2026

There is growing evidence that shows Clostridium (Clostridioides) difficile is a pathogen of One Health importance with a complex dissemination pathway involving animals, humans, and the environment. Thus, environmental discharge and agricultural recycling of human and animal waste have been suspected as factors behind the dissemination of Clostridium difficile in the community. Here, the presence of C. difficile in 12 wastewater treatment plants (WWTPs) in Western Australia was investigated. Overall, C. difficile was found in 90.5 % (114/126) of raw sewage influent, 48.1 % (50/104) of treated effluent, 40 % (2/5) of reclaimed irrigation water, 100 % (38/38) of untreated …

‘Male Circumcision’ And ‘Female Genital Mutilation’: Why Parents Choose The Procedures And The Case For Gender Bias In Medical Nomenclature, James L. Nuzzo

Research outputs 2022 to 2026

Cutting of boys’ and girls’ genitalia is a debated human rights topic. Here, the first aim was to summarise why parents choose to have these procedures performed on their children. Results from 22 survey studies on ‘male circumcision’ and 27 studies on ‘female genital mutilation’ revealed that non-medical reasons, such as tradition, are prominent in the decisions for both procedures. The second aim was to describe researchers’ use of medical words (i.e. ‘circumcision’) and non-medical words (i.e. ‘cutting’, ‘mutilation’) when referring to these procedures. Relevant phrases were searched in titles and abstracts of articles indexed in PubMed. Total article count …
