Association Between the Gut Microbiota and Blood Pressure in a Population Cohort of 6953 Individuals.
JOURNAL OF THE AMERICAN HEART ASSOCIATION - 04 Aug 2020
Background Several small-scale animal studies have suggested that gut microbiota and blood pressure (BP) are linked. However, results from human studies remain scarce and conflicting. We wanted to elucidate the multivariable-adjusted association between gut metagenome and BP in a large, representative, well-phenotyped population sample. We performed a focused analysis to examine the previously ...

Differing mechanisms of atrial fibrillation in athletes and non-athletes: alterations in atrial structure and function.
EUROPEAN HEART JOURNAL CARDIOVASCULAR IMAGING - 01 Dec 2020
Atrial fibrillation (AF) is more common in athletes and may be associated with adverse left atrial (LA) remodelling. We compared LA structure and function in athletes and non-athletes with and without AF.Individuals (144) were recruited from four groups (each n = 36): (i) endurance athletes with paroxysmal AF, (ii) endurance athletes without AF, (iii) non-athletes with paroxysmal AF, and (iv) n...
Metformin treatment in heart failure with preserved ejection fraction: a systematic review and meta-regression analysis.
CARDIOVASCULAR DIABETOLOGY - 05 Aug 2020
Observational series suggest a mortality benefit from metformin in the heart failure (HF) population. However, the benefit of metformin in HF with preserved ejection fraction (HFpEF) has yet to be explored. We performed a systematic review and meta-analysis to identify whether variation in EF impacts mortality outcomes in HF patients treated with metformin.MEDLINE and EMBASE were searched up to...
Molecular magnetic resonance imaging of activated platelets allows noninvasive detection of early myocarditis in mice.
SCIENTIFIC REPORTS - 06 Aug 2020
MRI sensitivity for diagnosis and localization of early myocarditis is limited, although it is of central clinical interest. The aim of this project was to test a contrast agent targeting activated platelets consisting of microparticles of iron oxide (MPIO) conjugated to a single-chain antibody directed against ligand-induced binding sites (LIBS) of activated glycoprotein IIb/IIIa (= LIBS-MPIO)...

This study focused on isolation and screening of Tet(X4)-positive Enterobacteriaceae from the gut microbiota of a cohort of healthy individuals in Singapore.MinION and Illumina sequencing was performed to obtain the complete genome se...
Does moxonidine reduce Achilles tendon or musculoskeletal pain in women with polycystic ovarian syndrome? A secondary analysis of a randomised controlled trial.
BMC ENDOCRINE DISORDERS - 26 Aug 2020
Sympathetic activity and insulin resistance have recently been linked with chronic tendon and musculoskeletal pain. Polycystic ovarian syndrome is linked with insulin resistance and increased sympathetic drive and was therefore an appropriate condition to study the effects of modulating sympathetic activity on Achilles tendon and musculoskeletal symptoms.A secondary analysis of a double-blinded...

All primary presentations w...
Agreement between the International Physical Activity Questionnaire and Accelerometry in Adults with Orthopaedic Injury.
INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH - 24 Aug 2020
Orthopaedic injury can lead to decreased physical activity. Valid measures for assessing physical activity are therefore needed in this population. The aim of this study was to determine the agreement and concordance between the International Physical Activity Questionnaire-Short Form (IPAQ) and device-measured physical activity and sitting time in orthopaedic injury patients. Adults with isola...
Lack of Strategic Funding and Long-Term Job Security Threaten to Have Profound Effects on Cardiovascular Researcher Retention in Australia.
HEART, LUNG & CIRCULATION - 21 Aug 2020
Cardiovascular disease is the leading cause of death in Australia. Investment in research solutions has been demonstrated to yield health and a 9.8-fold return economic benefit. The sector, however, is severely challenged with success rates of traditional peer-reviewed funding in decline. Here, we aimed to understand the perceived challenges faced by the cardiovascular workforce in Australia pr...
High-intensity interval training in patients with left ventricular assist devices: A pilot randomized controlled trial.
THE JOURNAL OF HEART AND LUNG TRANSPLANTATION : THE OFFICIAL PUBLICATION OF THE INTERNATIONAL SOCIETY FOR HEART TRANSPLANTATION - 01 Dec 2020
Left ventricular assist device (LVAD) implantation is an established treatment for patients with advanced heart failure. To date, studies evaluating the impact of aerobic training in patients with LVADs have focused on moderate-intensity exercise.This pilot randomized controlled trial compared the effects of high-intensity interval training (HIIT) with those of moderate-intensity continuous tra...

Is the Healthy Respiratory System Built Just Right, Overbuilt or Underbuilt to Meet the Demands Imposed by Exercise?
JOURNAL OF APPLIED PHYSIOLOGY (BETHESDA, MD. : 1985) - 13 Aug 2020
In the healthy, untrained young adult a case is made for a respiratory system- airways, pulmonary vasculature, lung parenchyma, respiratory muscles and neural ventilatory control system - which is near ideally designed to ensure a highly efficient, homeostatic response to exercise of varying intensities and durations. Our aim was then to consider circumstances in which the intra/extra-thoracic ...
Validation of a Genome-Wide Polygenic Score for Coronary Artery Disease in South Asians.
JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY - 11 Aug 2020
Genome-wide polygenic scores (GPS) integrate information from many common DNA variants into a single number. Because rates of coronary artery disease (CAD) are substantially higher among South Asians, a GPS to identify high-risk individuals may be particularly useful in this population.This analysis used summary statistics from a prior genome-wide association study to derive a new GPS for South...
The effect of breaking up prolonged sitting on paired associative stimulation-induced plasticity.
EXPERIMENTAL BRAIN RESEARCH - 01 Nov 2020
Paired associative stimulation (PAS) can induce plasticity in the motor cortex, as measured by changes in corticospinal excitability (CSE). This effect is attenuated in older and less active individuals. Although a single bout of exercise enhances PAS-induced plasticity in young, physically inactive adults, it is not yet known if physical activity interventions affect PAS-induced neuroplasticit...
