There is histological evidence of microstructural changes in the zygomaticotemporal branch of the trigeminal nerve in migraineurs. This raises the possibility that altered trigeminal nerve properties contribute to migraine pathophysiology. Whilst it is not possible to explore the anatomy of small trigeminal nerve branches it is possible to explore the anatomy of the trigeminal root entry zone u...

In response to dehydration, humans experience thirst. This subjective state is fundamental to survival as it motivates drinking, which subsequently corrects the fluid deficit. To elicit thirst, previous studies have manipulated blood chemistry to produce a physiological thirst stimulus. In the present study, we investigated whether a physiological stimulus is indeed required for thirst to be ex...

Contrast-induced acute kidney injury is not uncommon after percutaneous coronary intervention, particularly in high-risk patients. Pharmacologic approaches have not demonstrated significant benefit, and numerous device-based approaches exist targeting a variety of pathways. In this review, we summarize the most recent interventions and the evidence behind them.

Patients with acute pulmonary embolism (PE) are at risk of developing chronic complications including the post-PE syndrome with reduced cardiopulmonary function and chronic thromboembolism pulmonary hypertension (CTEPH). Risk stratification at PE diagnosis is an important tool in predicting early mortality; however, its use in predicting chronic complications has not been evaluated.  This stud...

Cardiac fibrosis and myocyte hypertrophy are hallmarks of the cardiac remodelling process in cardiomyopathies such as heart failure (HF). Dyslipidemia or dysregulation of lipids contribute to HF. The dysregulation of high density lipoproteins (HDL) could lead to altered levels of other lipid metabolites that are bound to it such as sphingosine-1- phosphate (S1P). Recently, it has been shown tha...

Glycaemic control in type 1 diabetes (T1DM) can be challenging, and is influenced by many factors. This study aimed to investigate glycaemic control and its associated factors in Chinese people with T1DM.This cross-sectional study included 779 participants with T1DM selected from hospital records review, outpatient clinics and inpatient wards. Data were collected via face to face interviews, me...

The United Arab Emirates National Diabetes and Lifestyle Study (UAEDIAB) has identified obesity, hypertension, obstructive sleep apnea, and dyslipidemia as common phenotypic characteristics correlated with diabetes mellitus status. As these phenotypes are usually linked with genetic variants, we hypothesized that these phenotypes share single nucleotide polymorphism (SNP)-clusters that can be u...

Hearing impairment (HI) is a leading impairment worldwide and identifying modifiable risk factors of HI may have major public health implications. The aim of this study was to investigate the association between obstructive sleep apnea (OSA) and HI.Observational longitudinal study (the Paris Prospective Study 3).Population-based.Volunteers aged 50-75 years and consulting at a preventive medical...

The key challenge for biosensing is to design biomarker-responsive contrast agents that can be readily detected and monitored by broadly available biomedical imaging modalities. While a range of biosensors have been designed for optical, photoacoustic, and magnetic resonance imaging (MRI) modalities, technical challenges have hindered the development of ultrasound biosensors, even though ultra...

Endothelial barrier disruption is a hallmark of tissue injury, edema, and inflammation. Vascular endothelial cells express the G protein-coupled receptor (GPCR) protease acctivated receptor 1 (PAR1) and the ion channel transient receptor potential vanilloid 4 (TRPV4), and these signaling proteins are known to respond to inflammatory conditions and promote edema through remodeling of cell-cell j...

Whole exome sequencing (WES) is a popular and successful technology which is widely used in both research and clinical settings. However, there is a paucity of reference data for Aboriginal Australians to underpin the translation of health-based genomic research. Here we provide a catalogue of variants called after sequencing the exomes of 50 Aboriginal individuals from the Northern Territory (...

Modern agriculture has dramatically changed the distribution of animal species on Earth. Changes to host ecology have a major impact on the microbiota, potentially increasing the risk of zoonotic pathogens being transmitted to humans, but the impact of intensive livestock production on host-associated bacteria has rarely been studied. Here, we use large isolate collections and comparative genom...

The web-based BeUpstanding Champion Toolkit was developed to support work teams in addressing the emergent work health and safety issue of excessive sitting. It provides a step-by-step guide and associated resources that equip a workplace representative-the champion-to adopt and deliver the 8-week intervention program (BeUpstanding) to their work team. The evidence-informed program is designed ...

This study uses longitudinal cohort data to estimate the impacts of air pollution on health outcomes among people first hospitalised with heart diseases. Despite the generally low level of pollution in Australia, we find that acute exposure to pollution increases readmissions to hospitals within 3-12 months after discharge and is more evident among those suffering from heart failure. We further...

The most important determinant of long-term survival in patients with idiopathic pulmonary fibrosis is the right ventricular (RV) adaptation to the increased pulmonary vascular resistance. Our aim was to explore RV contractile reserve during stress echocardiography in early-stage IPF.Fifty early-stage patients with IPF and 50 healthy control patients underwent rest and stress echocardiography, ...

To report the compliance and results of an electrocardiogram (ECG) cardiac screening program in male and female elite Australian cricketers.cross-sectional study.Elite cricketers were offered screening in accordance with Cricket Australia policy. Players who consented provided a personal and family history, physical examination and resting 12-lead ECG. An audit (1 February 2019) examined all ca...

Stem cell therapy has been tested for cardiac disease therapy for decades. Initially, researchers only considered stem cells’ differentiative ability to repair damaged cardiac tissue. However, studies have now uncovered novel mechanisms contributing to stem cell healing properties to repair injured cardiac tissue, including via paracrine signaling and exosome secretions, leading to amelioration...
