n-3 fatty acids reduce the risk of cardiovascular disease via a number of possible mechanisms. Despite this, there has been concern that these fatty acids may increase lipid peroxidation. The data in vivo are inconclusive, due in part to limitations in the methodologies. In this regard, the measurement of F2-isoprostanes provides a reliable assessment of in(More)
Brachial artery ultrasound is commonly employed for noninvasive assessment of endothelial function. However, analysis is observer dependent and susceptible to errors. We describe studies on a computerized edge-detection and wall-tracking software program to allow more accurate and reproducible measurement. In study 1, three purpose-built Perspex phantom(More)
BACKGROUND Type 2 diabetes and hypertension are both associated with an increased risk of atherothrombosis. We assessed whether purified eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from fish oil have differential effects on platelet, fibrinolytic and vascular function in patients with both conditions. METHODS In a double-blind(More)
BACKGROUND n-3 Fatty acids lower blood pressure, improve lipids, and benefit other cardiovascular disease risk factors. Effects on glycemia in patients with type 2 diabetes are uncertain. OBJECTIVE We determined whether purified eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) have differential effects on glycemic control, including insulin(More)
OBJECTIVES To assess possible associations between anticholinergic drug exposure and serum anticholinergic activity (SAA) and their capacities to predict all-cause mortality in older hospitalized patients. SETTING Academic medical center. PARTICIPANTS AND MEASUREMENTS Data on clinical characteristics, full medication exposure, SAA, and 4 anticholinergic(More)
The Drug Burden Index (DBI) is associated with poorer physical function in stable, community-dwelling, older people. The authors speculated that a higher DBI is associated with reduced physical function (Barthel Index, primary outcome) and predicts adverse outcomes (length of stay, in-hospital mortality, secondary outcomes) in frail, acutely ill, older(More)
H igh blood pressure (BP) is a leading risk factor contributing to the global burden of disease. Small changes in BP due to dietary modification may have a significant impact on the prevalence of hypertension and risk of cardiovascular disease. Tea is a popular beverage worldwide and is usually the major source of population flavonoid intake, often(More)
AIMS We studied the association between either non-selective NSAIDs (ns-NSAIDs), selective COX-2 inhibitors, or any NSAID and risk of incident myocardial infarction (MI) and heart failure (HF), and all-cause mortality in elderly subjects. METHODS We conducted a retrospective nested case-control study on Australian veterans using nationwide hospital(More)
AIM To determine whether in patients with an ambulance response time of >5min who were in VF cardiac arrest, 3min of CPR before the first defibrillation was more effective than immediate defibrillation in improving survival to hospital discharge. METHODS This randomised control trial was run by the South Australian Ambulance Service between 1 July, 2005,(More)
PURPOSE Studies on the risk of stroke in users of non-steroidal anti-inflammatory drugs (NSAIDs) have provided conflicting results. We studied the association between the use of non-selective ns-NSAIDs, selective COX-2 inhibitors, or either of these NSAIDs, and the incidence of stroke-related hospitalization in elderly subjects. METHODS We conducted a(More)
