Young Adults With High Autistic-Like Traits Displayed Lower Food Variety And Diet Quality In Childhood, Catherine Panossian, Philippa Lyons-Wall, Andrew Whitehouse, Wendy H. Oddy, Johnny Lo, Jane Scott, Therese O'Sullivan

Research outputs 2014 to 2021

This study explored the association between autistic-like traits in young adults and dietary intake in early childhood in the Gen2 Raine Study cohort. Data were available from 811 participants at years 1, 2 and 3 for the assessment of dietary intake, and at year 20 for measurement of autistic-like traits. Results showed as autistic-like traits increased, total food variety, core food variety and dairy variety decreased (p < 0.05), with a lower consumption of citrus fruits and yoghurt (both p = 0.04). As autistic-like traits increased, diet quality decreased, this trend was significant at 2 years (p = 0.024). Our results suggest that young adults with higher autistic-like traits were more likely to have had lower food variety and diet quality in early childhood.

Research outputs 2014 to 2021

Background: While therapeutic success of the limbal tissue or cell transplantation to treat severe cases of limbal stem cell (LSC) deficiency (LSCD) strongly depends on the percentage of LSCs within the transplanted cells, prospective LSC enrichment has been hampered by the intranuclear localization of the previously reported LSC marker p63. The recent identification of the ATP-binding cassette transporter ABCB5 as a plasma membrane-spanning marker of LSCs that are capable of restoring the cornea and the development of an antibody directed against an extracellular loop of the ABCB5 molecule stimulated us to develop a novel treatment strategy based on the utilization …

Prevalence Of Frailty And Pain In Hospitalised Adult Patients In An Acute Hospital: A Protocol For A Point Prevalence Observational Study, Rosemary Saunders, Kate Crookes, Mustafa Atee, Caroline Bulsara, Max K. Bulsara, Christopher Etherton-Beer, Beverley Ewens, Olivia Gallagher, Renee M. Graham, Karen Gullick, Sue Haydon, Kim-Huong Nguyen, Bev O'Connell, Karla Seaman, Jeff Hughes

Research outputs 2014 to 2021

Introduction Frailty and pain are associated with adverse patient clinical outcomes and healthcare system costs. Frailty and pain can interact, such that symptoms of frailty can make pain assessment difficult and pain can exacerbate the progression of frailty. The prevalence of frailty and pain and their concurrence in hospital settings are not well understood, and patients with cognitive impairment are often excluded from pain prevalence studies due to difficulties assessing their pain. The aim of this study is to determine the prevalence of frailty and pain in adult inpatients, including those with cognitive impairment, in an acute care private metropolitan …

Utility Of Serum Biomarker Indices For Staging Of Hepatic Fibrosis Before And After Venesection In Patients With Hemochromatosis Caused By Variants In Hfe, Justin Chin, Lawrie W. Powell, Louise E. Ramm, Gunter F. Hartel, John K. Olynyk, Grant A. Ramm

Research outputs 2014 to 2021

Background & Aims

Hemochromatosis that is associated with variants in the homeostatic iron regulator gene (HFE) is characterized by intestinal absorption of iron and excessive body and hepatic iron stores; it can lead to hepatic fibrosis and cirrhosis. Fibrosis has been staged by analysis of liver biopsies, but non-invasive staging methods are available. We evaluated the ability of aspartate aminotransferase:platelet ratio index (APRI), the fibrosis-4 (FIB-4) index, and gamma-glutamyl transferase:platelet ratio (GPR) to assess hepatic fibrosis staging in subjects with HFE-associated hemochromatosis, using liver biopsy-staged fibrosis as the reference standard.

Methods

We performed a retrospective, cross-sectional analysis of 181 subjects …

Background: Despite hospitalization for exacerbation being a high-risk event for morbidity and mortality, there is little consensus globally regarding the assessment and management of hospitalised exacerbations of COPD. We aimed to establish a consensus list of symptoms, physiological measures, clinical scores, patient questionnaires and investigations to be obtained at time of hospitalised COPD exacerbation and follow-up. Methods: A modified Delphi online survey with pre-defined consensus of importance, feasibility and frequency of measures at hospitalisation and follow-up of a COPD exacerbation was undertaken. Findings: A total of 25 COPD experts from 18 countries contributed to all 3 rounds of the survey. …

Widening The Lens On Capital: Conceptualising The University Experiences Of Non-Traditional Women Nurse Students, Lesley Andrew, Ken Robinson, Julie Dare, Leesa Costello

Research outputs 2014 to 2021

This article argues the insufficiency of the traditional application of cultural, social and economic capital in conceptualising the non-traditional student experience. Built on the thematic analysis of 52 in-depth interviews with 28 mature-age women nursing undergraduates with family responsibilities in Australia, an alternative, expanded model of capital is proposed.

The qualitative study, underpinned by Gadamer’s Hermeneutic Philosophy, revealed multiple threats and enablers to progression throughout the degree. Dimensions of capital previously unacknowledged in the nursing literature were necessary to fully conceptualise these rich and complex findings, including important student strengths. These dimensions: aspirational, navigational, resistant, familial and experiential capital, compensated …

Research outputs 2014 to 2021

Background While high-quality meta-analyses have confirmed the effectiveness of aphasia therapy after stroke, there is limited evidence for the comparative effectiveness of different aphasia interventions. Two commonly used interventions, Constraint-induced Aphasia Therapy Plus (CIAT Plus) and Multi-modality Aphasia Therapy (M-MAT), are hypothesised to rely on diverse underlying neural mechanisms for recovery and may be differentially responsive to aphasia severity. COMPARE is a prospective randomised open-blinded end-point trial designed to determine whether, in people with chronic post-stroke aphasia living in the community, CIAT Plus and M-MAT provide greater therapeutic benefit compared to usual care, are differentially effective according to aphasia severity, …

Effects Of Exercise During Radiotherapy On Physical Function And Treatment-Related Side Effects In Men With Prostate Cancer: A Systematic Review And Meta-Analysis, Oliver Schumacher, Hao Luo, Dennis Taaffe, Daniel A. Galvao, Colin Tang, Raphael Chee, Nigel Spry, Robert Newton

Research outputs 2014 to 2021

Purpose

Radiation therapy is a commonly used treatment for prostate cancer; however, the side effects may negatively affect quality of life and cause patients to be less physically active. Although exercise has been shown to mitigate radiation therapy–related fatigue in men with prostate cancer during radiation therapy, other adverse effects of treatment such as physical deconditioning, urinary symptoms, or sexual dysfunction have not been systematically reviewed in this patient population. Thus, the purpose of this review was to investigate the effect of exercise on physical function and treatment-related side effects in men with prostate cancer undergoing radiation therapy.

Quadruple Convergence – Rising Cannabis Prevalence, Intensity, Concentration And Use Disorder Treatment, Albert Stuart Reece, Gary Kenneth Hulse

Research outputs 2014 to 2021

In collating and synthesizing several data sources on cannabis exposure, Manthey and colleagues have elegantly compiled a foundational resource for subsequent epidemiological studies on cannabis use [1]. The study includes an impressive body of evidence on cannabis use prevalence (in the month and year prior to interview), high risk cannabis use (daily or near daily), tetrahydrocannabinol (THC—the principal psychoactive constituent of cannabis) concentration in European cannabis herb and processed resin (cannabis concentrates), and treatment demand for Cannabis Use Disorder (CUD). All four domains studied show a modest to dramatic increases across 2010-2019.

Brain injury, resulting from stroke and traumatic brain injury, is a common occurrence in Australia, with Aboriginal people affected at a significant rate and impact felt by individuals, families and communities. Access to brain injury rehabilitation services for Aboriginal people is reported to be often limited, with very little support outside the hospital environment. Our research involving Aboriginal brain injury survivors and their families to date has revealed that people often manage ‘on their own’ following such events. Following recommendations from survivors and their families, the Healing Right Way clinical trial, currently underway in Western Australia, has created the role …

A Delirium Prevalence Audit And A Pre And Post Evaluation Of An Interprofessional Education Intervention To Increase Staff Knowledge About Delirium In Older Adults, Bev Ewens, Karla Seaman, Lisa Whitehead, Mandy Towell-Barnard, Michelle Young

Research outputs 2014 to 2021

Background

Delirium is more prevalent in older people and estimated to occur in up to 50% of the hospital population. Delirium comprises a spectrum of behaviours, including cognitive and attention deficits, and fluctuating levels of consciousness, often associated with an underlying physiological disturbance. Delirium has been increasingly associated with adverse outcomes. Although often preventable or can at least be mitigated, delirium may not be a standard part of assessment and thus may not be recognized in the early stages when it is most likely to be treated successfully. The aim of this study was to evaluate the level of knowledge …

Cannabinoid Exposure As A Major Driver Of Pediatric Acute Lymphoid Leukaemia Rates Across The Usa: Combined Geospatial, Multiple Imputation And Causal Inference Study, Albert Stuart Reece, Gary K. Hulse

Research outputs 2014 to 2021

Background: Acute lymphoid leukaemia (ALL) is the commonest childhood cancer whose incidence is rising in many nations. In the USA, between 1975 and 2016, ALL rates (ALLRs) rose 93.51% from 1.91 to 3.70/100,000 < 20 years. ALL is more common in Caucasian-Americans than amongst minorities. The cause of both the rise and the ethnic differential is unclear, however, prenatal cannabis exposure was previously linked with elevated childhood leukaemia rates. We investigated epidemiologically if cannabis use impacted nationally on ALLRs, its ethnic effects, and if the relationship was causal. Methods: State data on overall, and ethnic ALLR from the Surveillance Epidemiology and End Results databank of the Centre for Disease Control (CDC) and National Cancer Institute (NCI) were combined with drug (cigarettes, alcoholism, cannabis, analgesics, cocaine) use data from the National Survey of Drug Use and Health; 74.1% response rate. Income and ethnicity data was from the US Census bureau. Cannabinoid concentration was from the Drug Enforcement Agency Data. Data was analyzed in R by robust and spatiotemporal regression. Results: In bivariate analyses a dose-response relationship was demonstrated between ALLR and Alcohol Use Disorder (AUD), cocaine and cannabis exposure, with the effect of cannabis being strongest (β-estimate = 3.33(95%C.I. 1.97, 4.68), P = 1.92 × 10− 6). A strong effect of cannabis use quintile on ALLR was noted (Chi.Sq. = 613.79, P = 3.04 × 10− 70). In inverse probability weighted robust regression adjusted for other substances, income and ethnicity, cannabis was independently significant (β-estimate = 4.75(0.48, 9.02), P = 0.0389). In a spatiotemporal model adjusted for all drugs, income, and ethnicity, cannabigerol exposure was significant (β-estimate = 0.26(0.01, 0.52), P = 0.0444), an effect increased by spatial lagging (THC: β-estimate = 0.47(0.12, 0.82), P = 0.0083). After missing data imputation ethnic cannabis exposure was significant (β-estimate = 0.64(0.55, 0.72), P = 3.1 × 10− 40). 33/35 minimum e-Values ranged from 1.25 to 3.94 × 1036 indicative of a causal relationship. Relaxation of cannabis legal paradigms had higher ALLR (Chi.Squ.Trend = 775.12, P = 2.14 × 10− 112). Cannabis legal states had higher ALLR (2.395 ± 0.039 v. 2.127 ± 0.008 / 100,000, P = 5.05 × 10− 10). Conclusions: Data show that ALLR is associated with cannabis consumption across space-time, is associated with the cannabinoids, THC, cannabigerol, cannabinol, cannabichromene, and cannabidiol, contributes to ethnic differentials, demonstrates prominent quintile effects, satisfies criteria for causality and is exacerbated by cannabis legalization.

Glucosinolates From Cruciferous Vegetables And Their Potential Role In Chronic Disease: Investigating The Preclinical And Clinical Evidence, Emma Connolly, Marc Sim, Nikolaj Travica, Wolfgang Marx, Gemma Beasy, Gordon S.

Research outputs 2014 to 2021

An increasing body of evidence highlights the strong potential for a diet rich in fruit and vegetables to delay, and often prevent, the onset of chronic diseases, including cardiometabolic, neurological, and musculoskeletal conditions, and certain cancers. A possible protective component, glucosinolates, which are phytochemicals found almost exclusively in cruciferous vegetables, have been identified from preclinical and clinical studies. Current research suggests that glucosinolates (and isothiocyanates) act via several mechanisms, ultimately exhibiting anti-inflammatory, antioxidant, and chemo-protective effects. This review summarizes the current knowledge surrounding cruciferous vegetables and their glucosinolates in relation to the specified health conditions. Although there is evidence that …

Mitochondrial dysfunction including deficits of mitophagy is seen in aging and neuro-degenerative disorders including Alzheimer’s disease (AD). Apart from traditionally targeting amyloid beta (Aβ), the main culprit in AD brains, other approaches include investigating impaired mitochondrial pathways for potential therapeutic benefits against AD. Thus, a future therapy for AD may focus on novel candidates that enhance optimal mitochondrial integrity and turnover. Bi-oactive food components, known as nutraceuticals, may serve as such agents to combat AD. Uro-lithin A is an intestinal microbe-derived metabolite of a class of polyphenols, ellagitannins (ETs). Urolithin A is known to exert many health benefits. Its antioxidant, …
