Cerebral amyloid angiopathy (CAA) is a type of cerebrovascular disorder characterised by the accumulation of amyloid within the leptomeninges and small/medium-sized cerebral blood vessels. Typically, cerebral haemorrhages are one of the first clinical manifestations of CAA, posing a considerable challenge to the timely diagnosis of CAA as the bleedings only occur during the later disease stages. Fluid biomarkers may change prior to imaging biomarkers, and therefore, they could be the future of CAA diagnosis. Additionally, they can be used as primary outcome markers in prospective clinical trials. Among fluid biomarkers, blood-based biomarkers offer a distinct advantage over cerebrospinal fluid biomarkers …

In Vivo Human Medial Gastrocnemius Fascicle Behaviour And Belly Gear During Submaximal Eccentric Contractions Are Not Affected By Concentric Fatiguing Exercise, Matheus Daros Pinto, Kazunori Nosaka, Anthony J. Blazevich

Research outputs 2022 to 2026

Changes in muscle geometry and belly gearing during eccentric contractions influence fibre strain and susceptibility to muscle damage. They are modulated by the interaction between connective tissues and intracellular-intrafascicular fluid pressures and external pressures from neighbouring structures. Fatiguing exercise triggers fluid shifts (muscle swelling) and muscle activation changes that may influence these modulators. Our purpose was to measure medial gastrocnemius (MG) geometric changes in vivo during eccentric contractions before and after maximal concentric muscle work to test the hypothesis that fatigue would reduce fascicle rotation and muscle gear and provoke greater fascicle strain. Submaximal eccentric plantar flexor contractions at 40% …

Research outputs 2022 to 2026

Sleep-wake disturbances are common in neurodegenerative diseases and may occur years before the clinical diagnosis, potentially either representing an early stage of the disease itself or acting as a pathophysiological driver. Therefore, discovering biomarkers that identify individuals with sleep-wake disturbances who are at risk of developing neurodegenerative diseases will allow early diagnosis and intervention. Given the association between sleep and neurodegeneration, the most frequently analyzed fluid biomarkers in people with sleep-wake disturbances to date include those directly associated with neurodegeneration itself, such as neurofilament light chain, phosphorylated tau, amyloid-beta and alpha-synuclein. Abnormalities in these biomarkers in patients with sleep-wake disturbances …

Research outputs 2022 to 2026

γ-secretase processing of amyloid precursor protein (APP) has long been of interest in the pathological progression of Alzheimer's disease (AD) due to its role in the generation of amyloid- . The catalytic component of the enzyme is the presenilins of which there are two homologues, Presenilin-1 (PS1) and Presenilin-2 (PS2). The field has focussed on the PS1 form of this enzyme, as it is typically considered the more active at APP processing. However, much of this work has been completed without appropriate consideration of the specific levels of protein expression of PS1 and PS2. We propose that expression is an …

Acute kidney injury (AKI) is characterized by a rapid reduction in renal function and glomerular filtration rate (GFR). The broadly used anti-cancer chemotherapeutic agent cisplatin often induces AKI as an adverse drug side effect. Therapies targeted at the reversal of AKI and its potential progression to chronic kidney disease or end-stage renal disease are currently insufficiently effective. Mesenchymal stromal cells (MSCs) possess diverse immunomodulatory properties that confer upon them significant therapeutic potential for the treatment of diverse inflammatory disorders. Human dermal MSCs expressing ATP-Binding Cassette member B5 (ABCB5) have shown therapeutic efficacy in clinical trials in chronic skin wounds or …

Introduction: Brain metastases commonly occur in patients with non-small cell lung cancer (NSCLC). Standard first-line treatment for NSCLC, without an EGFR, ALK or ROS1 mutation, is either chemoimmunotherapy or anti-PD-1 monotherapy. Traditionally, patients with symptomatic or untreated brain metastases were excluded from the pivotal clinical trials that established first-line treatment recommendations. The intracranial effectiveness of these treatment protocols has only recently been elucidated in small-scale prospective trials. Methods: Patients with NSCLC and brain metastases, treated with first-line chemoimmunotherapy or anti-PD-1 monotherapy were selected from the Australian Registry and biObank of thoracic cancers (AURORA) clinical database covering seven institutions. The primary …

How Do Professional Connections And Relationships Impact Midwives’ Well-Being And Career Sustainability? A Grounded Theory Study Protocol, Lynnelle Moran, Sara Bayes, Kim Foster

Research outputs 2022 to 2026

Significant attrition and projected workforce shortages within the midwifery profession are global issues. Extensive research has identified that high levels of workplace adversity, chronic stress, and increasing rates of vicarious trauma and moral injury experienced by midwives, underpin this situation. Researchers have explored midwives’ intention to stay in the midwifery workforce and identified ways to support students’ transition to professional practice. Supportive collegial relationships have been reported to be protective for new and early career midwives’ well-being and resilience. However, there is a gap in knowledge and understanding of the impact and significance of professional connections and relationships for midwives …

Parent Implementation Of A Treatment For Late Talkers Based On Cross-Situational Statistical Learning Principles: Treatment Fidelity And Acceptability, Suzanne J. Meldrum, Jennifer Fisk, Jennifer Stopher, Emily F. Hunt

Research outputs 2022 to 2026

Purpose:

Early intervention based on principles of cross-situational statistical learning (CSSL) for late-talking children has shown promise. This study explored whether parents could be trained to deliver this intervention protocol with fidelity and if they found the intervention to be acceptable.

Method:

Mothers of four English-speaking children aged 18–30 months who scored < 10th centile for expressive vocabulary were recruited to an 8-week group training program. Parents were taught principles of CSSL and asked to perform 16 home treatment sessions (30 minutes each) in total, providing auditory bombardment of target words in full sentences at high dose number and syntactic variability, using a range of physical exemplars. Home diaries and two videotaped sessions measured treatment fidelity. Pre- and post-treatment questionnaires measured acceptability. Result: One parent discontinued the study after the second group training session. Three parents completed 15/16 group training sessions and reported completing 87% of home sessions. Two parents demonstrated implementing the intervention as per the target dose number by the first fidelity session (Weeks 2/3), and the third parent was very close to meeting target dose number by the second fidelity session (Weeks 7/8).

Conclusion:

Parents can be trained to deliver an intervention based on cross-situational statistical learning principles.

Determining the child’s best interests in a hospital setting will ideally involve the combined views of children, parents, and healthcare professionals. However, few studies have explored parents’ experiences of their child’s best interests when they engage with the healthcare system. Therefore, this study aimed to explore parents’ experiences of their child’s best interests during hospitalisation. A descriptive qualitative inductive design using face-to-face parent–child combined interviews, analysed by latent content analysis, was used. Sixteen parents recruited from a tertiary hospital in Western Australia were interviewed. Collaboration, development of trustworthy relationships, and effective communication were essential in shaping parents’ experiences of their …
