Research outputs 2022 to 2026

Observational studies revealed changes in Immunoglobulin G (IgG) N-glycosylation during the aging process. However, it lacks causal insights and remains unclear in which direction causal relationships exist. The two-sample bidirectional Mendelian randomization (MR) design was adopted to explore causal associations between IgG N-glycans and the senescence-associated secretory phenotype (SASP). Inverse variance weighted (IVW) and Wald ratio methods were used as the main analyses, supplemented by sensitivity analyses. Forward MR analyses revealed causal associations between the glycan peak (GP) and SASP, including GP6 (odds ratio [OR] = 0.428, 95% confidence interval [CI] = 0.189–0.969) and GP17 (OR = 0.709, 95%CI = …

The Role Of Mating Effort And Co-Residence History In Step-Grandparental Investment, Jenni E. Pettay, David A. Coall, Mirkka Danielsbacka, Antti O. Tanskanen

Research outputs 2022 to 2026

The prevalence of divorce in both parental and grandparental generations has led to a rise in the number of children who now have families that include both biological and step-grandparents. Despite the thorough examination of biological grandparents' contributions in the recent literature, there remains a scarcity of studies focusing on the investment of step-grandparents. Using population-based data from a sample of 2494 parents in Germany, we assessed grandparental investment through financial support and assistance with childcare of grandparents (N = 4238) and step-grandparents (N = 486). The study revealed that step-grandparents provided lower levels of investment in their grandchildren compared …

Well-Being Literacy In The Academic Landscape: Trioethnographic Inquiry Into Scholarly Writing, Narelle Lemon, Jacqui Francis, Lisa M. Baker

Research outputs 2022 to 2026

Writing well and being well as academic writers is rarely spoken about, often hidden, and at times evaded. We believe that developing, maintaining, and growing well-being literacy not only engages the act but also allows awareness, reflection, and metacognitive thinking that enable mindful writing for well-being. Well-being literacy, the capacity to understand and employ well- being language for personal, collective, and global well-being, intrigues us. It encompasses nurturing, sustaining, and safeguarding well-being for individuals, groups, and systems to thrive. As scholars delving into well-being literacy, we, a diverse collective from across higher education career trajectories, investigate its role in scholarly …

Research outputs 2022 to 2026

Frailty is an important concept in the care of older adults. Over the past two decades, significant advances have been made in measuring frailty. While it is now well-recognised that frailty status is an important determinant of outcomes from medical illnesses or surgical interventions, frailty measurement is not currently routinely integrated into clinical practice. In the community setting, it is uncommon for general practitioners to deliver frailty-optimised care. In hospitals, there is substantial variability in how people living with frailty are managed. This variability is notable between and even within disciplines. Furthermore, gains from understanding frailty mechanisms and risk factors …

Factors Affecting Clinician Readiness To Adopt Smart Home Technology For Remote Health Monitoring: Systematic Review, Gordana Dermody, Daniel Wadsworth, Melissa Dunham, Courtney Glass, Roschelle Fritz

Research outputs 2022 to 2026

Background: The population of older adults worldwide continues to increase, placing higher demands on primary health care and long-term care. The costs of housing older people in care facilities have economic and societal impacts that are unsustainable without innovative solutions. Many older people wish to remain independent in their homes and age in place. Assistive technology such as health-assistive smart homes with clinician monitoring could be a widely adopted alternative to aged-care facilities in the future. While studies have found that older persons have demonstrated a readiness to adopt health-assistive smart homes, little is known about clinician readiness to adopt …

Vulnerable, Recalcitrant And Resilient: A Foucauldian Discourse Analysis Of Risk And Older People Within The Context Of Covid-19 News Media, Marjorie Skoss, Rachel Batten, Patricia Cain, Mandy Stanley

Research outputs 2022 to 2026

Risk is an innate and integral part of everyday life and is present in simple, everyday occupations and complex actions. Age-related stereotypes can mean older people have little opportunity to engage in activities that present some degree of risk. The present study explores the discourse around risk and older people in the context of the COVID-19 pandemic. We investigated news media as a reflection of the dominant public discourse around older people's behaviour to identify how risk is represented in relation to occupational engagement. Texts relating to older people and COVID-19 were sourced from the West Australian newspaper for a …

The Experiences Of Older Immigrants Living With Dementia In Australia: A Multi-Method Secondary Analysis, Pelden Chejor

Theses: Doctorates and Masters

The ageing immigrant population and rising dementia cases underscores the need for culturally appropriate dementia care services. However, accessing dementia care services can be challenging for immigrants due to cultural and linguistical differences including their health beliefs. Understanding the experiences and concerns of older immigrants living with dementia is imperative for the planning and delivery of culturally and linguistically appropriate care. The aim of this thesis was to explore and describe the experiences of older immigrants living with dementia, as well as to describe and compare (against non-immigrants living with dementia) the characteristics (neuropsychiatric symptoms and pain characteristics) of older …

Preparing For End Of Life In A New Country: A Grounded Theory Study On African Migrants Living In Australia, Gertrude Gondwe Phiri

Theses: Doctorates and Masters

African migration to Australia has grown in the past 20 to 25 years with many migrants staying permanently. This has led to migrants dying away from their birthplaces where family is responsible for end-of-life care planning for the individual. Although migrating to Australia is considered a great achievement, many migrants also experienced challenges. Previous studies have explored the barriers faced by migrants in relation to end-of-life care but have not addressed the cause of those challenges. This constructivist grounded theory study examines how migrants from three African countries, Malawi, Zambia, and Zimbabwe (MZZ) prepare for end-of-life in Australia. The study …

Alzheimer’s disease (AD) pathology develops many years before the onset of cognitive symptoms. Two pathological processes—aggregation of the amyloid- (A ) peptide into plaques and the microtubule protein tau into neurofibrillary tangles (NFTs)—are hallmarks of the disease. However, other pathological brain processes are thought to be key disease mediators of A plaque and NFT pathology. How these additional pathologies evolve over the course of the disease is currently unknown. Here we show that proteomic measurements in autosomal dominant AD cerebrospinal fluid (CSF) linked to brain protein coexpression can be used to characterize the evolution of AD pathology over a timescale …

Predictors Of The Intention To Participate In Slum Upgrading Projects: Perceptions Of Slum Dwellers In Mauritius, Mohammad Shahidul Hasan Swapan, Saalem Sadeque, Md Sayed Iftekhar, Neshen Sooben

Research outputs 2022 to 2026

A global shift in urban slum improvement programmes is underway to step beyond the conventional approach by practicing a more participatory approach. Previous studies have found that slum upgrading projects are likely to be ineffective and unsustainable without the active participation of slum dwellers. Therefore, it is imperative to identify the pathways to improve or enhance slum dwellers’ participation in slum upgrading projects. Several studies highlight the need to consider socio-psychological attributes of the community. However, empirical evidence of the comparative significance of these attributes in predicting participatory behavioural intention of the slum dwellers has not been previously explored. In …

This scoping review aimed to explore what is known about palliative and End-of-Life (EOL) care access by immigrants with culturally and linguistically diverse (CALD) background living in high-income Organization for Economic Co-operation and Development (OECD) countries. CaLD immigrants have low utilization of palliative care services with patients’ family members taking up the role of caring, leading to immigrants not fully benefiting from the specialized services that are offered to alleviate suffering and promote quality of life. While there is some research in this area mainly in Europe, it cannot be said about all high-income OECD countries. Achieving person-centered care in …

Utility Of Dna Methylation As A Biomarker In Ageing And Alzheimer’S Disease, Lidija Milicic, Tenielle Porter, Michael Vacher, Simon M. Laws

Research outputs 2022 to 2026

Epigenetic mechanisms such as DNA methylation have been implicated in a number of diseases including cancer, heart disease, autoimmune disorders, and neurodegenerative diseases. While it is recognized that DNA methylation is tissue-specific, a limitation for many studies is the ability to sample the tissue of interest, which is why there is a need for a proxy tissue such as blood, that is reflective of the methylation state of the target tissue. In the last decade, DNA methylation has been utilized in the design of epigenetic clocks, which aim to predict an individual’s biological age based on an algorithmically defined set …

Ageing Reduces Persistent Inward Current Contribution To Motor Neurone Firing: Potential Mechanisms And The Role Of Exercise, Lucas B. R. Orssatto, Anthony J. Blazevich, Gabriel S. Trajano

Research outputs 2022 to 2026

Nervous system deterioration is a primary driver of age-related motor impairment. The motor neurones, which act as the interface between the central nervous system and the muscles, play a crucial role in amplifying excitatory synaptic input to produce the desired motor neuronal firing output. For this, they utilise their ability to generate persistent (long-lasting) depolarising currents that increase cell excitability, and both amplify and prolong the output activity of motor neurones for a given synaptic input. Modulation of these persistent inward currents (PICs) contributes to the motor neurones’ capacities to attain the required firing frequencies and rapidly modulate them to …
