BACKGROUND Results of previous randomised trials have shown that interventions that lower LDL cholesterol concentrations can significantly reduce the incidence of coronary heart disease (CHD) and other major vascular events in a wide range of individuals. But each separate trial has limited power to assess particular outcomes or particular categories of(More)
Puborectalis avulsion is a likely etiological factor for female pelvic organ prolapse (FPOP). We performed a study to establish minimal sonographic criteria for the diagnosis of avulsion. We analysed datasets of 764 women seen at a urogynecological service. Offline analysis of ultrasound datasets was performed blinded to patient data. Tomographic ultrasound(More)
Overweight and physical inactivity are risk factors for increased disease burden and health care expenditure. Well-designed studies are still needed to determine the treatment efficacy of worksite interventions targeting such risk factors. This randomized controlled trial was conducted at one of Australia's casinos in 2002-2003, to investigate the effects(More)
BACKGROUND Patients who have had a first episode of unprovoked venous thromboembolism have a high risk of recurrence after anticoagulants are discontinued. Aspirin may be effective in preventing a recurrence of venous thromboembolism. METHODS We randomly assigned 822 patients who had completed initial anticoagulant therapy after a first episode of(More)
OBJECTIVE Diabetes, a major health problem worldwide, increases the risk of cardiovascular disease and its associated mortality: The Long-Term Intervention with Pravastatin in Ischemic Disease (LIPID) trial showed that cholesterol-lowering treatment with pravastatin reduced mortality and coronary heart disease (CHD) events in 9014 patients aged 31-75 years(More)
OBJECTIVES This study investigates the effectiveness of 24-week aerobic and weight-training exercise plus behavior modification for mental health and quality of life (QOL) outcomes. METHODS Mental health and QOL data was collected using the Depression Anxiety and Stress Scales and SF-36 Health Status Survey, respectively. Employees from a single work-site(More)
BACKGROUND Whether statin therapy is as effective in women as in men is debated, especially for primary prevention. We undertook a meta-analysis of statin trials in the Cholesterol Treatment Trialists' (CTT) Collaboration database to compare the effects of statin therapy between women and men. METHODS We performed meta-analyses on data from 22 trials of(More)
OBJECTIVE To study whether avulsion and ballooning are independent risk factors for symptoms and/or signs of pelvic organ prolapse. DESIGN Retrospective analysis of data obtained in clinical practice. SETTING Tertiary urogynecology unit. POPULATION Seven hundred and sixty-one consecutive women with symptoms of pelvic floor dysfunction. METHODS(More)
The levator ani muscle is generally thought to play a role in urinary continence, with incontinence assumed to be due to abnormal muscle function or morphology. This study examined whether avulsion of the puborectalis muscle is associated with symptoms or signs of bladder dysfunction. In a retrospective observational study, we reviewed the records of 425(More)
BACKGROUND The clinically appropriate range for oxygen saturation in preterm infants is unknown. Previous studies have shown that infants had reduced rates of retinopathy of prematurity when lower targets of oxygen saturation were used. METHODS In three international randomized, controlled trials, we evaluated the effects of targeting an oxygen saturation(More)
