Newton, Dennis R. Taaffe, Kerri Winters-Stone, Laurien M. Buffart, Daniel A. Galvão

Research outputs 2022 to 2026

Purpose: To examine the effects and moderators of exercise effects on cardiometabolic outcomes in men with prostate cancer previously or currently undergoing androgen deprivation therapy (ADT). Results: Seven trials including 560 patients were examined. Exercise resulted in significant effects on whole-body and regional fat mass (P ≤ 0.001). For whole-body fat mass, significant exercise effects were observed in patients who were unmarried (−1.4 kg, P < 0.05) and who presented with higher fat mass levels (−1.0 kg, P < 0.05). For diastolic blood pressure and low-density lipoprotein (LDL), younger (−4.7 mmHg, P < 0.05) and older patients (−0.2 mmol.l-1, P < 0.10) achieved greater effects, respectively. Regarding high-density lipoprotein (HDL), patients undertaking ADT + prostatectomy + radiotherapy derived significant exercise effects (0.3 mmol.l-1, P < 0.05). Conclusions: Exercise effectively reduces fat mass across subgroups of men undergoing or following ADT with different characteristics. For diastolic blood pressure, HDL and LDL, groups based on age and treatment history could be specifically targeted with exercise medicine.

Research outputs 2022 to 2026

Connected adaptive resistance exercise (CARE) machines are new technology purported to adjust resistance exercise loads in response to muscle fatigue. The present study examined muscle fatigue (strength loss, fatigue perceptions) during maximal eccentric-only (ECCmax-only), concentric-only (CONmax-only), and coupled ECC-CON (ECCmax-CONmax) bicep curl exercise on a CARE machine. Eleven men and nine women completed the three protocols in separate sessions and in random order. All protocols included 4 sets of 20 maximal effort muscle contractions. Strength loss was calculated as Set 4 set end load minus Set 1 highest load. The CARE machine's algorithm adjusted resistances automatically, permitting continued maximal effort …

The Eccentric:Concentric Strength Ratio Of Human Skeletal Muscle In Vivo: Meta-Analysis Of The Influences Of Sex, Age, Joint Action, And Velocity, James L. Nuzzo, Matheus D. Pinto, Kazunori Nosaka, James Steele

Research outputs 2022 to 2026

For decades, researchers have observed that eccentric (ECC) muscle strength is greater than concentric (CON) muscle strength. However, knowledge of the ECC:CON strength ratio is incomplete and might inform resistance exercise prescriptions. Our purposes were to determine the magnitude of the ECC:CON ratio of human skeletal muscle in vivo and explore if sex, age, joint actions/exercises, and movement velocity impact it. A total of 340 studies were identified through searches. It was possible to analyse 1516 ECC:CON ratios, aggregated from 12,546 individuals who made up 564 groups in 335 of the identified studies. Approximately 98% of measurements occurred on isokinetic …

METHODS: a total of 22,194 pain assessments were reviewed in people with dementia (n = 3,144) from 34 different Australian aged care homes and two dementia specific programs. Pain assessments were conducted by 389 purposely trained health care professionals and cares using …

Kinetics Of Wound Development And Healing Suggests A Skin-Stabilizing Effect Of Allogeneic Abcb5+ Mesenchymal Stromal Cell Treatment In Recessive Dystrophic Epidermolysis Bullosa, Elke Niebergall-Roth, Kathrin Dieter, Cristina Daniele, Silvia Fluhr, Maria Khokhrina, Ines Silva, Christoph Ganss, Markus H. Frank, Mark A. Kluth

Research outputs 2022 to 2026

Recessive dystrophic epidermolysis (RDEB) is a rare, inherited, and currently incurable skin blistering disorder characterized by cyclically recurring wounds coexisting with chronic non-healing wounds. In a recent clinical trial, three intravenous infusions of skin-derived ABCB5+ mesenchymal stromal cells (MSCs) to 14 patients with RDEB improved the healing of wounds that were present at baseline. Since in RDEB even minor mechanical forces perpetually provoke the development of new or recurrent wounds, a post-hoc analysis of patient photographs was performed to specifically assess the effects of ABCB5+ MSCs on new or recurrent wounds by evaluating 174 wounds that occurred after baseline. During …

Research outputs 2022 to 2026

The effect of treatment dose on recovery of post-stroke aphasia is not well understood. Inconsistent conceptualization, measurement, and reporting of the multiple dimensions of dose hinders efforts to evaluate dose-response relations in aphasia rehabilitation research. We review the state of dose conceptualization in aphasia rehabilitation and compare the applicability of 3 existing dose frameworks to aphasia rehabilitation research—the Frequency, Intensity, Time, and Type (FITT) principle, the Cumulative Intervention Intensity (CII) framework, and the Multidimensional Dose Articulation Framework (MDAF). The MDAF specifies dose in greater detail than the CII framework and the FITT principle. On this basis, we selected the MDAF …

Mapping The Evidence On Assessment Of Fitness To Work At Heights: A Scoping Review Protocol, Lyndsey Swart, Nicolaas Claassen, Tania Buys

Research outputs 2022 to 2026

Introduction Falls from height are a leading cause of serious injury and fatality globally. In South Africa, work at heights is regulated by occupational health and safety legislation, which places responsibility on employers to ensure their workers are fit for high-risk work. There is however no formal procedure or consensus on how fitness to work at heights should be assessed. This paper presents an a priori protocol for a scoping review that seeks to identify and map the current evidence base around the assessment of fitness to work at heights. It forms the initial phase of a PhD study aimed …

Research outputs 2022 to 2026

Current approaches to staging chronic liver diseases have limited utility for predicting liver cancer risk. Here, we employed single-nucleus RNA sequencing (snRNA-seq) to characterize the cellular microenvironment of healthy and pre-malignant livers using two distinct mouse models. Downstream analyses unraveled a previously uncharacterized disease-associated hepatocyte (daHep) transcriptional state. These cells were absent in healthy livers but increasingly prevalent as chronic liver disease progressed. Copy number variation (CNV) analysis of microdissected tissue demonstrated that daHep-enriched regions are riddled with structural variants, suggesting these cells represent a pre-malignant intermediary. Integrated analysis of three recent human snRNA-seq datasets confirmed the presence of a …

Research outputs 2022 to 2026

Antimicrobial resistance (AMR) is one of the key public health concerns the world is facing today. The effect of antibiotic awareness campaigns (AACs) on consumer behaviour has been documented in the literature with mixed results. Understanding the mechanism for how AACs affect target populations is vital in designing effective and tailored campaigns. Using structural equation modelling our study examined the relationships among people's exposure to antibiotic awareness campaigns, knowledge of AMR prevention, AMR risk perception, and intention to seek antibiotic treatment. This study also tested the moderating effect of anxiety and societal responsibility on preventing AMR, and on their intention …

Behavioural changes and neuropsychiatric symptoms (NPS) commonly occur in Alzheimer’s disease (AD) but may not be recognised as AD-related when they are the presenting feature. NPS are important as they are associated with greater functional impairment, poorer quality of life, accelerated cognitive decline and worsened caregiver burden.1 Autosomal dominant AD (ADAD), although < 1% of total AD cases, provides a valuable opportunity to study the clinical heterogeneity of AD. The young age at onset reduces the prevalence of age-related comorbid pathologies and the near 100% penetrance of pathogenic mutations reduces the likelihood of misdiagnosis.2 Anxiety and depression commonly occur in ADAD family members, with increased levels of depression having been found among predementia female mutation carriers.3 Subsequent studies, however, have shown that anxiety and/or depression are common regardless of mutation status, occurring in almost one in three at-risk individuals, with one study reporting a higher rate of depression in non-carriers (17%) than asymptomatic carriers (5%).4 5 Despite the high frequency of NPS in ADAD families, relatively little is known about the proportion of ADAD cases who present with predominantly behavioural symptoms. Our aims were to assess the first reported clinical change in symptomatic ADAD, to compare presentations across genotypes, and to compare cognitive performance between behavioural and cognitive-led presentations.

Research outputs 2022 to 2026

Background: Dietary nitrate has a controversial role in human health. For over half a century, the nitrate content of the three major dietary sources – vegetables, meat, and water – has been legislated, regulated, and monitored due to public health concerns over cancer risk. In contrast, a growing and compelling body of evidence indicates that dietary nitrate, particularly from vegetables, protects against cardiovascular disease and other chronic diseases. This evidence for the protective effect of nitrate is overshadowed by the potential for nitrate to form carcinogenic N-nitrosamines. Scope and approach: The nitrate content, regulations and estimated intake from vegetables, meat …
