Exploring Traditional Breast Cancer Risk Genes Among Aboriginal And Torres Strait Islander Women, Katie Meehan, Leanne Pilkington, Azim Khan, Nicholas Pachter, Lisa Spalding, Ayeisha Milligan Armstrong, Cameron Redfern, Andrew Redfern

Research outputs 2022 to 2026

Background: Germline pathogenic variants in BRCA1/2 increase breast and ovarian cancer risk, but their prevalence in Aboriginal and Torres Strait Islander (herein referred to as Aboriginal) families has never been studied. Consequently, their contribution to breast cancer in this population is unknown.

Methods: This retrospective cohort study included 259 Aboriginal women and 789 age- and remoteness-matched non-Aboriginal women diagnosed with breast cancer (2001–2016). We assessed family history, genetic service referral and testing rates, and pathogenic variant rates in the context of testing access.

Results: Family history data were available for more Aboriginal than non-Aboriginal cases (46% vs. 34%, p < 0.001), with no difference in reported first-degree relatives with breast (22.5% vs. 22.4%, p = 0.98) or ovarian cancer (4.2% vs. 2.2%, p = 0.29). Similar proportions were referred to genetic services for testing eligibility (5.4% vs. 7.2%, p = 0.392). Of those referred, similar proportions were offered testing (86% vs. 81%, p = 0.66). Across the full cohort, BRCA1/2 pathogenic variants were detected in 0.77% of Aboriginal versus 2.4% of non-Aboriginal women (p = 0.127); any pathogenic gene variant was detected in 0.77% versus 3.0% (p = 0.039).

Research outputs 2022 to 2026

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that develops many years before clinical symptoms appear. The biological changes involved in the earliest stages remain poorly understood, particularly during the preclinical stage. Our previous work has identified gradual gut microbial and metabolic changes during this stage, suggesting these may represent early biological shifts that precede disease progression. Recent studies suggest that the gut microbiome may contribute to early AD processes through its effects on immune regulation, metabolism, and gut–brain communication. Changes in gut microbial composition, including reduced levels of short-chain fatty acid (SCFA)-producing bacteria, such as Faecalibacterium, Roseburia, and Eubacterium, …

Safety And Effectiveness Of Behavioural Activation For Chronic Pain: A Protocol For A Systematic Review And Meta-Analysis Of Randomised Controlled Trials, Fangyuan Zheng, Laura Hynes, Richard J. Gray, Irene Ngune, Jacqueline Sin, Martin Jones

Research outputs 2022 to 2026

Background/Objectives: Chronic pain is a prevalent and complex condition associated with substantial physical, psychological, and social burden. Behavioural activation (BA), a structured psychological intervention originally developed for depression, may be relevant to chronic pain through its focus on reducing behavioural avoidance and increasing engagement in meaningful activities. Although BA has been applied in studies involving people with chronic pain, the safety and effectiveness of BA in this population have not been comprehensively synthesised. This systematic review and meta-analysis will examine the safety and effectiveness of BA for people with chronic pain.

Research outputs 2022 to 2026

Introduction – Pain assessment remains challenging in healthcare settings in patients who are unable to self-report their pain. More than 50% of individuals with dementia and other forms of cognitive impairment (CI) experience pain daily. However, pain is frequently overlooked and inadequately assessed by healthcare professionals due to their lack of knowledge and guidelines to inform pain assessment. Pain is also a leading cause of hospital presentation and inappropriate pain assessment can impact on pain management and compromise safe and quality care. Evidence-based guidelines that inform appropriate pain assessment and management are therefore essential. This scoping review aimed to explore …

Muscle–Tumor Crosstalk In Exercise Oncology: Exercise-Induced Myokines And Cancer Cachexia, Amirhossein Ahmadi Hekmatikar, Francesco Bettariga, Álvaro López Llorente, Diego Fernández-Lázaro, Katsuhiko Suzuki, D. Maryama Awang Daud

Research outputs 2022 to 2026

Exercise-induced myokines, such as IL-6, irisin, and myostatin, play crucial roles in mediating systemic adaptations and modulating tumor progression. This narrative review synthesizes evidence on how regular moderate-intensity exercise affects the myokine network within the tumor microenvironment (TME) of solid tumors. Results from the 86 included studies indicate that structured training (aerobic: 45–65% VO2 max; resistance: 45–70% 1RM) enhances the expression of beneficial myokines that support immune surveillance, reduce inflammation, and improve muscle–tumor cross-talk. IL-6 demonstrates a dual modulatory effect on inflammation and immunity; irisin contributes to tumor apoptosis, while myostatin downregulation supports muscle integrity and metabolic balance. Evidence suggests …
