Research outputs 2014 to 2021

Circulating tumour DNA (ctDNA) has emerged as a promising blood-based biomarker for monitoring disease status of patients with advanced cancers. In melanoma, ctDNA has been shown to have clinical value as an alternative tumour source for the detection clinically targetable mutations for the assessment of response to therapy. This review provides a critical summary of the evidence that gives credence to the utility of ctDNA as a biomarker for monitoring of disease status in advanced melanoma and the steps required for its implementation into clinical settings.

Over-Provision Of Discretionary Foods At Childcare Dilutes The Nutritional Quality Of Diets For Children, Ruth M. Wallace, Leesa N. Costello, Amanda Devine

Research outputs 2014 to 2021

The childcare setting can significantly influence the lifelong eating habits and health outcomes of children.It is ideal for health-promoting interventions that optimise the provision of nutritious food and nutrition education. Unfortunately, these interventions are neither offered nor promoted in many childcare settings. Recent studies have indicated an increased risk of overweight/obesity with childcare attendance, which if present in early life is associated with increased risk of chronic disease and reduced psychological wellbeing.

Do Muscle Strength Imbalances And Low Flexibility Levels Lead To Low Back Pain? A Brief Review, Cassio Victora Ruas, Adriane Vieira

Research outputs 2014 to 2021

Chronic low back pain (CLBP) has been related to hips, trunk and spine strength imbalances and/or low flexibility levels. However, it is not clear if the assessment and normalization of these variables are effective for prevention of low back pain (LBP) episodes and rehabilitation of patients with CLBP. This brief review explored studies that have associated hip, trunk and spine strength imbalances and/or low flexibility levels to LBP episodes or CLBP condition. Fourteen studies were selected by accessing PubMed and Google Scholar databases. Collectively, the selected studies demonstrate that trunk eccentric/concentric and flexion/extension strength imbalances may be associated with CLBP …

Single-Leg Squats Can Predict Leg Alignment In Dancers Performing Ballet Movements In "Turnout", Luke Hopper, Nahoko Sato, Andries L. Weidemann

Research outputs 2014 to 2021

The physical assessments used in dance injury surveillance programs are often adapted from the sports and exercise domain. Bespoke physical assessments may be required for dance, particularly when ballet movements involve “turning out” or external rotation of the legs beyond that typically used in sports. This study evaluated the ability of the traditional single-leg squat to predict the leg alignment of dancers performing ballet movements with turnout. Three-dimensional kinematic data of dancers performing the single-leg squat and five ballet movements were recorded and analyzed. Reduction of the three-dimensional data into a one-dimensional variable incorporating the ankle, knee, and hip joint …

The Interpretive Approach As A Means Of Understanding The Misunderstood, Doreen Molloy, Joyce Hendricks, Anne Williams

Research outputs 2014 to 2021

People’s experiences of health and illness are important areas of health research and practice. The interpretive process, and more significantly the biographical approach (Denzin, 1989), is an approach in which there is a focus on personal epiphanies which shape and reflect the stories people tell of their experiences. Dolby-Stahl (1985) contends stories of personal experience sit within the genre of folklore and that the reading of such stories must take into account the social, cultural, and historical contexts which influence and give meaning to experience.

The Efficacy Of A Group Cognitive Behavioral Therapy For War-Affected Young Migrants Living In Australia: A Cluster Randomized Controlled Trial, Chew S. Ooi, Rosanna M. Rooney, Clare Roberts, Robert T. Kane, Bernadette Wright, Nikos Chatzisarantis

Research outputs 2014 to 2021

Background: Preventative and treatment programs for people at risk of developing psychological problems after exposure to war trauma have mushroomed in the last decade. However, there is still much contention about evidence-based and culturally sensitive interventions for children. The aim of this study was to examine the efficacy of the Teaching Recovery Techniques in improving the emotional and behavioral outcomes of war-affected children resettled in Australia.

Methods and Findings: A cluster randomized controlled trial with pre-test, post-test, and 3-month follow-up design was employed. A total of 82 participants (aged 10–17 years) were randomized by school into the 8-week intervention ( …

Photoaging Photography: Mothers' Attitudes Toward Adopting Skin-Protective Measures Pre- And Post-Viewing Photoaged Images Of Their And Their Child's Facial Sun Damage, Matthew Welch, Paul Chang, Myra F. Taylor

Research outputs 2014 to 2021

One of the major sources for children to gain knowledge of skin-protective measures is from their parents. Therefore, an imperative exists for parents to model and reinforce the sun-safety practices they want their children to adopt. Although Australian mothers have been the recipients of two extensive sun-safety public health campaigns, little is known about their attitudes, behaviors, and application of health promotion knowledge toward their and their child’s ultraviolet (UV) sun exposure. Ten mothers with children aged 4 to 12 years were asked a series of questions about their sun-safety practices, both pre- and post-viewing an UV photoaged photograph of …

Integrating Diet And Exercise Into Care Of Prostate Cancer Patients On Androgen Deprivation Therapy, Mark A. Moyad, Robert Newton, Ulf W. Tunn, Damian Gruca

Research outputs 2014 to 2021

Improved diagnosis and treatment regimens have resulted in greater longevity for men with prostate cancer. This has led to an increase in both androgen deprivation therapy (ADT) use and duration of exposure, and therefore to its associated adverse effects, such as sexual dysfunction, osteoporosis, reduced muscle mass, increased fat mass, and increased incidence of cardiovascular disease and type 2 diabetes. Given that the adverse effects of ADT are systemic, often debilitating, and difficult to treat, efforts continue in the development of new strategies for long-term management of prostate cancer. The PubMed database was searched to select trials, reviews, and meta-analyses …

Local Muscle Metabolic Demand Induced By Neuromuscular Electrical Stimulation And Voluntary Contractions At Different Force Levels: A Nirs Study, Makii Muthalib, Graham Kerr, Kazunori Nosaka, Stephane Perrey

Research outputs 2014 to 2021

Functional Muscle metabolic demand during contractions evoked by neuromuscular electrical stimulation (NMES) has been consistently documented to be greater than voluntary contractions (VOL) at the same force level (10-50% maximal voluntary contraction-MVC). However, we have shown using a near-infrared spectroscopy (NIRS) technique that local muscle metabolic demand is similar between NMES and VOL performed at MVC levels, thus controversy exists. This study therefore compared biceps brachii muscle metabolic demand (tissue oxygenation index-TOI and total hemoglobin volume-tHb) during a 10s isometric contraction of the elbow flexors between NMES (stimulation frequency of 30Hz and current level to evoke 30% MVC) and VOL …

Research outputs 2014 to 2021

In the last decade, Clostridium difficile infection (CDI) has reached an epidemic state with increasing incidence and severity in both health care and community settings. Vancomycin is an important first-line therapy for CDI, and the emergence of resistance would have significant clinical consequences. In this study, we describe for the first time a vanB2 vancomycin resistance operon in C. difficile, isolated from an Australian veal calf at slaughter. The operon was carried on an ~ 42-kb element showing significant homology and synteny to Tn1549, a conjugative transposon linked with the emergence and global dissemination of vancomycin-resistant enterococci …

Real-Time Netnography: Rejecting The Passive Shift, Leesa Costello, Marie-Louise Mcdermott

Research outputs 2014 to 2021

Although netnography emerged in the 1990s, it is a term unfamiliar to many ethnographers and is still touted as a new methodology. Once explained, ethnographers often understand it in terms of online ethnography. While this is helpful, netnography, however, offers a set of steps and analytic approaches that can be applied across a spectrum of involvement online. Its focus is on gaining entree to an online community, distinguishing between participant observation and nonparticipant observation.

The Role Of Clinical Proteomics, Lipidomics, And Genomics In The Diagnosis Of Alzheimer's Disease, Ian James Martins

Research outputs 2014 to 2021

The early diagnosis of Alzheimer’s disease (AD) has become important to the reversal and treatment of neurodegeneration, which may be relevant to premature brain aging that is associated with chronic disease progression. Clinical proteomics allows the detection of various proteins in fluids such as the urine, plasma, and cerebrospinal fluid for the diagnosis of AD. Interest in lipidomics has accelerated with plasma testing for various lipid biomarkers that may with clinical proteomics provide a more reproducible diagnosis for early brain aging that is connected to other chronic diseases. The combination of proteomics with lipidomics may decrease the biological variability between …

Medical Help-Seeking For Sexual Concerns In Prostate Cancer Survivors, Melissa K. Hyde, Leah Zajdlewicz, Addie C. Wootten, Christian J. Nelson, Anthony Lowe, Jeff Dunn, Suzanne K. Chambers

Research outputs 2014 to 2021

Introduction: Although sexual dysfunction is common after prostate cancer, men's decisions to seek help for sexual concerns are not well understood.

Aim: Describe predictors of actual prior help-seeking and intended future medical help-seeking for sexual dysfunction in prostate cancer survivors.

Methods: A cross-sectional survey of 510 prostate cancer survivors assessed masculine beliefs, attitudes, support/approval from partner/peer networks (subjective norm), and perceived control as predictors of medical help-seeking for sexual concerns. A theory of planned behavior (TPB) perspective was used to examine actual prior and planned future behavior and contributing factors. Statistical analyses included multiple and logistic regressions.

Research outputs 2014 to 2021

Background:

Despite a decade of substantial investments in programs to improve access to primary care for Aboriginal mothers and infants, more than 50 % of Western Australian Aboriginal babies are still not receiving primary and preventative care in the early months of life. Western Australian hospitals now input birth data into the Western Australian electronic clinical management system within 48 hours of birth. However, difficulties have arisen in ensuring that the appropriate primary care providers receive birth notification and clinical information by the time babies are discharged from the hospital. No consistent process exists to ensure that choices about primary …

Epidemiology And Risk Factors For Community-Associated Clostridium Difficile Infection: A Narrative Review, Lauren E. Bloomfield, Thomas V. Riley

Research outputs 2014 to 2021

Clostridium difficile infection (CDI) was once considered a primarily nosocomial concern. Emerging evidence from the last 20 years has highlighted a drastic shift in the known epidemiology of CDI, with disease outside of hospitals apparently occurring more frequently and causing severe disease in populations that were thought to be at low risk. This narrative review summarises potential pathways for infection outside of the hospital environment and highlights likely routes of transmission. Further, evidence is presented on potential risk factors for development of disease. Understanding the epidemiology of CDI outside of hospitals is essential to the ability to prevent and control …

Impaired Energy Metabolism: Involvement In Neurodegenerative Processes And Cns Ageing, Veer B. Gupta, Vivek K. Gupta

Research outputs 2014 to 2021

World is experiencing a consistent and steady increase in the ageing population with even higher proportional differences in the developed countries. Increase in ageing populations is directly correlated with the increased prevalence of age-related degenerative diseases of the central nervous system (CNS) such as Alzheimer’s disease and various other forms of dementias, stroke, Parkinson’s disease, retinal degenerative disorders, Huntington’s’ disease, multiple sclerosis, psychiatric and behavioural disorders amongst others.

Bacterial Lipopolysaccharides Change Membrane Fluidity With Relevance To Phospholipid And Amyloid Beta Dynamics In Alzheimer's Disease, Ian James Martins

Research outputs 2014 to 2021

Bacterial lipopolysaccharides (LPS) and their increase in plasma in individuals in the developing world has become of major concern. LPS can transform cells by their rapid insertion into cell membranes that partition into cholesterol/sphingomyelin domains. LPS alter cell phospholipid dynamics associated with the recruitment of the Alzheimer’s disease amyloid beta (Aβ) peptide with the promotion of toxic Aβ oligomer formation. The common pattern of naturally occurring phospholipids such as1-palmitoyl-2-oleolyl-phosphatidylcholine in cells confers cells with the rapid transfer of Aβ and phospholipids. Phospholipids such as dipalmitoylphosphatidylcholine (DPPC), dimyristoylphosphatidylcholine (DMPC) and dioleoylphosphatidylcholine (DOPC) are poorly transported with delayed metabolism of Aβ oligomers. …

China Suboptimal Health Cohort Study: Rationale, Design And Baseline Characteristics, Youxin Wang, Siqi Ge, Yuxiang Yan, Anxin Wang, Zhongyao Zhao, Xinwei Yu, Jing Qui, Mohamed Ali Alzain, Hao Wang, Honghong Fang, Qing Gao, Manshu Song, Jie Zhang, Yong Zhou, Wei Wang

Research outputs 2014 to 2021

Background:

Suboptimal health status (SHS) is a physical state between health and disease, characterized by the perception of health complaints, general weakness, chronic fatigue and low energy levels. SHS is proposed by the ancient concept of traditional Chinese medicine (TCM) from the perspective of preservative, predictive and personalized (precision) medicine. We previously created the suboptimal health status questionnaire 25 (SHSQ-25), a novel instrument to measure SHS, validated in various populations. SHSQ-25 thus affords a window of opportunity for early detection and intervention, contributing to the reduction of chronic disease burdens.

Methods/design:

To investigate the causative effect of SHS in non-communicable …
