Obesity has long been identified as a noteworthy risk factor for cardiovascular diseases, including aortic stenosis. Nevertheless, an unexplained phenomenon known as the obesity paradox has arisen in the context of transcatheter aortic valve implantation (TAVI), inquiring conventional beliefs. The obesity paradox refers to better clinical outcomes observed in obese individuals undergoing TAVI. These include reduced all-cause mortality, lower rates of procedural complications, and improved long-term survival rates compared to their lean counterparts. Several theories have been proposed to explain the obesity paradox in TAVI. One of the most popular is the adipose tissue-mediated cardioprotective effect hypothesis. It is known …

Tuberculosis (TB) primarily manifests as pulmonary TB (PTB), but extrapulmonary TB (EPTB) remains a major clinical challenge. Distinct diagnostic and therapeutic difficulties arise from differences in immune responses, pathogen behaviour and host susceptibility. However, the factors driving disease localisation are still incompletely understood. We conducted a comprehensive narrative review of studies examining differences between PTB and EPTB in terms of epidemiology, mycobacterial factors, genetic and epigenetic determinants, host immune responses, transcriptomic profiles, cytokine and chemokine patterns, and immunophenotypes. EPTB is more common among females, children, older adults and immunocompromised individuals with deficient granuloma formation. This review is intended to provide …

Background: Ependymoma is a malignancy of the neuroepithelium-derived ependyma that lines the spinal cord and ventricles of the brain, occurring most frequently in young children and older adults. Genetic susceptibility to ependymoma has proven difficult to assess due to disease rarity.

Methods: We performed genome-wide association studies (GWAS) of 478 ependymoma patients and 4,841 disease-free controls of European ancestry. Ependymoma patients consisted of 117 children (< 18 years old) with whole-genome sequencing (WGS), 142 children with genotyping, and 219 adults (≥18 years old) with genotyping. Genotyped samples were imputed using the 1,000 Genomes Project as the reference panel and underwent quality control filtering. The GWAS was performed separately by age group and technology (genotyped or WGS). GWAS variants were considered significant at P < 5 × 10-8.

Results: Among pediatric subjects with WGS data, we identified a significant intronic variant in EDIL3 (rs149378, P = 1.9 × 10-8) and a nearly significant intronic variant in LHX4 (rs79008224, P = 7.2 …

Insulin Resistance As A Mediator Of Physical Activity's Effects On Beta-Amyloid Accumulation And Tau Phosphorylation: A Scoping Review, Michael G. Slee, Joanne Scotney, Stephanie R. Rainey-Smith, Kirk I. Erickson, Hamid R. Sohrabi, Giuseppe Verdile, Belinda M. Brown

Research outputs 2022 to 2026

Background Type 2 diabetes is associated with increased Alzheimer’s disease risk and brain beta amyloid (Aβ) burden, suggesting an underlying mechanistic relationship between Alzheimer’s disease and type 2 diabetes. Animal studies show exercise reduces levels of brain Aβ and tau, and while human studies are somewhat limited, some studies have reported physical activity is associated with lower brain Aβ and tau levels. Exercise has well established links to reductions in insulin resistance; thus, as physical activity can impact both insulin resistance and Alzheimer’s disease pathology and/or biomarkers, it is reasonable to hypothesise that a mediating relationship may exist. The objective …

Research outputs 2022 to 2026

Purpose: A growing body of evidence suggests diets rich in flavonoids may protect against metabolic-dysfunction associated steatotic liver disease (MASLD) development and progression. As the gut microbiome is important in the biotransformation of flavonoids to their constituent bioactive metabolites, studies on the potential mediating role of the gut microbiome in the association between dietary flavonoid intakes and MASLD are warranted but lacking. Thus, this study aims to examine the associations between a diet rich in flavonoids and MASLD, and assess the potential mediating role of the gut microbiome. Methods: In a cross-sectional analysis (n = 531), using the FlavoDiet score …

Two Strategies To Improve Stability In A Precision-Based Task: Insights From The Badminton Short Serve, Yochi Iino, Jodie Cochrane Wilkie, Senshi Fukashiro, Shinsuke Yoshioka, Shayne Vial

Research outputs 2022 to 2026

The badminton short serve is a highly precise task requiring accurate control of racquet face orientation, which directly influences shuttlecock trajectory and limits an opponent's ability to attack. Previous studies on motor redundancy have emphasized covariation among elemental variables as the primary mechanism for stabilizing performance. However, when the sensitivities of elemental variables differ, performance can also be stabilized by unevenly distributing individual variances without altering correlation — an approach that has received limited attention. This study investigated whether elite players use both the correlation strategy and the uneven variance strategy to stabilize racquet face angles during the short serve. …

Alzheimer’s disease (AD), a complex neurodegenerative disorder characterised by progressive cognitive decline, affects millions globally. With no current cure, treatment focuses on symptom management and slowing disease progression. Early identification is therefore crucial. Fecal microRNA (miRNA) analysis is emerging as a promising non-invasive diagnostic tool. Evidence suggests that miRNAs present in fecal samples may regulate gene expression linked to AD pathology, impacting cellular functions and disease progression. Dietary factors critically influence gut microbiota composition and diversity, affecting brain health via the gut brain axis. Macronutrients such as carbohydrates, proteins, and fats modulate miRNA expression and gut microbiota, influencing AD risk. …

Addressing Professional Tensions Through Intellectual Candour And Stewardship, Thoughtful Dialoguing As A Duoethnographic Collaborative Exploration, Sarah Barradell, Narelle Lemon

Research outputs 2022 to 2026

Using duoethnography, we explore our experiences of physiotherapy practice and education and argue that the profession’s desire for credibility is at the expense of vulnerability, risk and intellectual candour–of imagining the profession and education of its graduates differently. We identified key themes around: alignment/misalignment, reflection/reflexivity and professional scope. This methodology models risk and questioning through the juxtaposition of different perspectives. Through our contrasting narratives, we remain open to new forms of learning, modelling what intellectual candour demands from us: facing the problems of the past so that we might learn from our history and change our future. This can be …
