Determining thresholds for spatial urban design and transport features that support walking to create healthy and sustainable cities: findings from the IPEN Adult study.
THE LANCET. GLOBAL HEALTH - 01 Jun 2022
An essential characteristic of a healthy and sustainable city is a physically active population. Effective policies for healthy and sustainable cities require evidence-informed quantitative targets. We aimed to identify the minimum thresholds for urban design and transport features associated with two physical activity criteria: at least 80% probability of engaging in any walking for transport ...
Mortality trends in type 1 diabetes: a multicountry analysis of six population-based cohorts.
DIABETOLOGIA - 01 Jun 2022
Mortality has declined in people with type 1 diabetes in recent decades. We examined how the pattern of decline differs by country, age and sex, and how mortality trends in type 1 diabetes relate to trends in general population mortality.We assembled aggregate data on all-cause mortality during the period 2000-2016 in people with type 1 diabetes aged 0-79 years from Australia, Denmark, Latvia, ...
Excess all-cause and cause-specific mortality for people with diabetes and end-stage kidney disease.
DIABETIC MEDICINE : A JOURNAL OF THE BRITISH DIABETIC ASSOCIATION - 01 Jun 2022
Excess mortality is high in the setting of diabetes and end-stage kidney disease (ESKD), but the effects of ESKD beyond diabetes itself remains incompletely understood. We examined excess mortality in people with diabetes with versus without ESKD, and variation by age, sex and diabetes type.This study included 63,599 people with type 1 (aged 20-69 years; 56% men) and 1,172,160 people with type ...

EUROPEAN HEART JOURNAL. QUALITY OF CARE & CLINICAL OUTCOMES - 06 Jun 2022
We sought to investigate if sex disparity exists for secondary prevention pharmacotherapy following acute coronary syndrome (ACS) and impact on long-term clinical outcomes.We analysed data on medical management 30-day post-percutaneous coronary intervention (PCI) for ACS in 20 976 patients within the multicentre Melbourne Interventional Group registry (2005-2017). Optimal medical therapy (OMT) ...
Abundance of Nef and p-Tau217 in Brains of Individuals Diagnosed with HIV-Associated Neurocognitive Disorders Correlate with Disease Severance.
MOLECULAR NEUROBIOLOGY - 01 Feb 2022
HIV-associated neurocognitive disorders (HAND) is a term used to describe a variety of neurological impairments observed in HIV-infected individuals. The pathogenic mechanisms of HAND and of its connection to HIV infection remain unknown, but one of the considered hypotheses suggests that HIV infection accelerates the development of Alzheimer's disease. Previous studies suggested that HIV-1 Nef...
A Combined Echocardiography Approach for the Diagnosis of Cancer Therapy-Related Cardiac Dysfunction in Women With Early-Stage Breast Cancer.
JAMA CARDIOLOGY - 01 Mar 2022
Diagnosis of cancer therapy-related cardiac dysfunction (CTRCD) remains a challenge. Cardiovascular magnetic resonance (CMR) provides accurate measurement of left ventricular ejection fraction (LVEF), but access to repeated scans is limited.To develop a diagnostic model for CTRCD using echocardiographic LVEF and strain and biomarkers, with CMR as the reference standard.In this prospective cohor...
Protein phosphatase 2A in the healthy and failing heart: New insights and therapeutic opportunities.
CELLULAR SIGNALLING - 01 Mar 2022
Protein phosphatases have emerged as critical regulators of phosphoprotein homeostasis in settings of health and disease. Protein phosphatase 2A (PP2A) encompasses a large subfamily of enzymes that remove phosphate groups from serine/threonine residues within phosphoproteins. The heterogeneity in PP2A structure, which arises from the grouping of different catalytic, scaffolding and regulatory s...
Impact on adolescent mental health of replacing screen-use with exercise: A prospective cohort study.
JOURNAL OF AFFECTIVE DISORDERS - 15 Mar 2022
Screen-based device use could increase the risk of adolescent depression. Distinct modalities of screen-use may have differential effects on mental health. We used compositional data analysis to examine how theoretically replacing different screen-uses with exercise might influence future adolescent emotional distress.In 4,599 adolescents (55% female) from a nationally-representative, prospecti...
Arrhythmogenic Right Ventricular Cardiomyopathy.
JACC. CLINICAL ELECTROPHYSIOLOGY - 01 Apr 2022
Arrhythmogenic right ventricular cardiomyopathy (ARVC) encompasses a group of conditions characterized by right ventricular fibrofatty infiltration, with a predominant arrhythmic presentation. First described in the late 1970s and early 1980s, it is now frequently recognized to have biventricular involvement. The prevalence is ∼1:2,000 to 1:5,000, depending on geographic location, and it has a ...
Vasoplegia Following Orthotopic Heart Transplantation: Prevalence, Predictors and Clinical Outcomes.
JOURNAL OF CARDIAC FAILURE - 01 Apr 2022
Patients undergoing heart transplant are at high risk for postoperative vasoplegia. Despite its frequency and association with poor clinical outcomes, there remains no consensus definition for vasoplegia, and the predisposing risk factors for vasoplegia remain unclear. Accordingly, the aim of this study was to evaluate the prevalence, predictors, and clinical outcomes associated with vasoplegia...
Screening-guided spironolactone treatment of subclinical left ventricular dysfunction for heart failure prevention in at-risk patients.
EUROPEAN JOURNAL OF HEART FAILURE - 01 Apr 2022
Subclinical left ventricular dysfunction (LVD) is a prelude to symptomatic heart failure (HF). We hypothesised that screening-guided treatment with spironolactone would prevent incident HF in at-risk patients.We randomised asymptomatic, community-dwelling subjects aged ≥65 years old, with at least one non-ischaemic HF risk factor (hypertension, type 2 diabetes mellitus or obesity) to echocardio...
Mechanosensing by Piezo1 and its implications for physiology and various pathologies.
BIOLOGICAL REVIEWS OF THE CAMBRIDGE PHILOSOPHICAL SOCIETY - 01 Apr 2022
Piezo1 is a mechanosensitive ion channel with essential roles in cardiovascular, lung, urinary, and immune functions. Piezo1 is widely distributed in different tissues in the human body and its specific roles have been identified following a decade of research; however, not all are well understood. Many structural and functional characteristics of Piezo1 have been discovered and are known to di...
Germline variants in tumor suppressor FBXW7 lead to impaired ubiquitination and a neurodevelopmental syndrome.
AMERICAN JOURNAL OF HUMAN GENETICS - 07 Apr 2022
Neurodevelopmental disorders are highly heterogenous conditions resulting from abnormalities of brain architecture and/or function. FBXW7 (F-box and WD-repeat-domain-containing 7), a recognized developmental regulator and tumor suppressor, has been shown to regulate cell-cycle progression and cell growth and survival by targeting substrates including CYCLIN E1/2 and NOTCH for degradation via th...
Using magnetic resonance imaging to map the hidden burden of muscle involvement in systemic sclerosis.
ARTHRITIS RESEARCH & THERAPY - 11 Apr 2022
Skeletal muscle can be directly affected by systemic sclerosis (SSc); however, a significant burden of SSc-associated myopathy is undetected because clinical parameters such as weakness and creatine kinase (CK) are unreliable biomarkers of muscle involvement. This study presents qualitative and quantitative magnetic resonance imaging (MRI) findings that quantify the prevalence of myopathy and e...
Vascular Responses Among Adults Four Years Post Exposure to 6 Weeks of Smoke from the Hazelwood Coal Mine Fire.
VASCULAR HEALTH AND RISK MANAGEMENT - 01 Jan 2022
Mega-wild fires are exposing large communities to weeks or months of high concentration smoke-related fine particulate air pollution (PM). However, little research has examined the long-term vascular responses from exposure to PM of this concentration and duration. We investigated whether level of exposure to 6 weeks of PM from the 2014 Hazelwood coal mine fire was associated with abnormal vasc...

Prescription trends and costs of diabetes medications in Australia between 2003 and 2019: an analysis and review of the literature.
INTERNAL MEDICINE JOURNAL - 01 May 2022
Since the turn of the century, the prevalence of diabetes mellitus in Australia has increased, primarily due to rising rates of Type 2 diabetes. Simultaneously, the landscape of diabetes medications has evolved significantly. The change in prescribing trends and public spending on diabetes medications within Australia during this period are not well defined.To establish the frequency and cost o...
