Indigenous people experience a higher burden of nutrition-related conditions and are more likely to experience food insecurity compared to non-Indigenous people. Consequently, they remain at increased risk of malnutrition; particularly when residing in regional or remote areas. This study aims to compare and characterise the burden and nature of malnutrition among a representative cohort of Ind...

Patients with a cardiac history are at future risk of cardiac events, including out-of-hospital cardiac arrest. Targeting cardiopulmonary resuscitation (CPR) training to family members of cardiac patients has long been advocated, but is an area in need of contemporary research evidence. An environment yet to be investigated for targeted training is cardiac rehabilitation.To evaluate the feasibi...

Current phase mapping systems for atrial fibrillation create 2-dimensional (2D) maps. This process may affect the accurate detection of rotors. We developed a 3-dimensional (3D) phase mapping technique that uses the 3D locations of basket electrodes to project phase onto patient-specific left atrial 3D surface anatomy.We sought to determine whether rotors detected in 2D phase maps were present ...

Acute Kidney Injury (AKI) complicates the management of at least 25% of patients with severe burns and is associated with long term complications. Most research focuses on the patients with more severe burns, and whether the same factors are associated with the development of AKI in patients with burns between 10 and 19% total body surface area (TBSA) is unknown. The aims of this study were to ...

The creation of advanced nursing roles in diabetes management, with specific skills such as nurse prescribing, has resulted in nurses taking on roles that have traditionally been associated with doctors.We aimed to examine the effectiveness of nurse-led clinics, in which nurses were involved in prescribing, on haemoglobin A1c (HbA1c) among people with type 2 diabetes.We systematically searched ...

Oxidative stress is a causal factor in the development of diabetic retinopathy; however, clinically relevant strategies to treat the disease by augmenting antioxidant defense mechanisms have not been fully explored. We hypothesized that boosting nuclear factor erythroid-2-related factor 2 (Nrf2) antioxidant capacity with the novel Nrf2 activator dh404, would protect the retina in diabetes inclu...

Catheter ablation has become standard of care in patients with symptomatic atrial fibrillation (AF). Although there have been significant advances in our understanding and technology, a substantial proportion of patients have ongoing AF requiring repeat procedures. Pulmonary vein isolation (PVI) is the cornerstone of AF ablation; however, it is less effective in patients with persistent as oppo...

Chronic cardiometabolic diseases, including cardiovascular disease (CVD), type 2 diabetes (T2D) and chronic kidney disease (CKD), share many modifiable risk factors and can be prevented using combined prevention programs. Valid risk prediction tools are needed to accurately identify individuals at risk.We aimed to validate a previously developed non-invasive risk prediction tool for predicting ...

Left ventricular (LV) ejection fraction (LVEF) is a simple measure of global systolic function that pervades the risk evaluation and management of many cardiovascular diseases. However, this parameter is limited not only by technical challenges, but also by pathophysiological entities where the ratio of stroke volume to LV cavity size is preserved. The assessment of global longitudinal strain (...

The aim of this study was to perform a systematic review and meta-analysis to estimate the normal ranges of magnetic resonance imaging (MRI)-based feature tracking (FT) and to identify sources of variations. Similar analyses were also performed for strain encoding, displacement encoding with stimulated echoes, and myocardial tagging.MRI-FT is a novel technique for quantification of myocardial d...

This study sought to measure the impact on all-cause death or readmission of adding center-based exercise training (ET) to disease management programs for patients with a recent acute heart failure (HF) hospitalization.ET is recommended for patients with HF, but evidence is based mainly on ET as a single intervention in stable outpatients.A randomized, controlled trial with blinded outcome asse...

Five International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) surveys since 1998 have estimated the volume and type of bariatric surgery being done in constituent member countries. These reports did not include baseline demographic descriptions.An IFSO Global Registry pilot project in 2014 demonstrated that it was possible to amalgamate large numbers of individual pati...

Severely obese adolescents harbor numerous cardiovascular disease risk factors (CVD-RFs), which improve after metabolic and bariatric surgery (MBS). However, predictors of change in CVD-RFs among adolescents have not yet been reported.The Teen-Longitudinal Assessment of Bariatric Surgery study (NCT00474318) prospectively collected anthropometric and health status data on 242 adolescents undergo...

Growth/differentiation factor 8 (GDF8), or myostatin, negatively regulates muscle mass. GDF8 is held in a latent state through interactions with its N-terminal prodomain, much like TGF-β. Using a combination of small-angle X-ray scattering and mutagenesis, we characterized the interactions of GDF8 with its prodomain. Our results show that the prodomain:GDF8 complex can exist in a fully latent s...

Objective measures of environmental attributes have been used to understand how neighborhood environments relate to physical activity. However, this method relies on detailed spatial data, which are often not easily available. Walk Score® is a free, publicly available web-based tool that shows how walkable a given location is based on objectively-derived proximity to several types of local dest...

Global assessments of burden of disease suggests there are sex differences in risk factors for chronic disease, including overweight/obesity, dietary patterns and habitual physical activity. Given that prevention efforts aim to target such factors to reduce disease risk, the age at which sex differences may occur is of particular interest. Early life to young adulthood is the optimal time for i...

Sterol 27-hydroxylase (CYP27A1) catalyzes the hydroxylation of cholesterol to 27-hydroxycholesterol (27-OHC) and regulates cholesterol homeostasis. In () double knockout (KO) mice fed with Western diet (WD), the atherosclerotic phenotype found in KO mice was reversed. As protective mechanism, up-regulation of and was proposed. heterozygote/ KO (het) mice, with reduced expression and norma...

Depression is a prevalent, independent predictor of mortality in patients with heart failure (HF). Depression is also common in type 2 diabetes mellitus (T2DM), which is itself an important risk factor for HF. However, association of depression with incident HF in T2DM is undefined. The aim of the present study was to evaluate the predictive value of depression in predicting incident HF in a co...
