METHODS(More)
Polyfluoroalkyl chemicals (PFCs) have been used worldwide for more than 50 years in a wide variety of industrial and consumer products. Limited data exist on human exposure to PFCs in the Southern Hemisphere. Human blood serum collected in southeast Queensland, Australia, in 2006-2007 from 2420 donors was pooled according to age (cord blood, 0-0.5, 0.6-1,(More)
OBJECTIVE The aim was to examine the accuracy of magnetic resonance imaging (MRI) in predicting circumferential resection margin (CRM) involvement, T- and N-stage in patients with locally advanced carcinoma of the rectum, who had undergone long-course downstaging chemoradiation (CRT). METHOD Patients with rectal cancer were selected for long-course(More)
OBJECTIVES To assess the level of depressive symptomatology in a community based group of patients with Parkinson's disease (PD) and their carers and to investigate the patient characteristics that might predict carer distress. METHODS The GDS-15 geriatric depression scale was used to measure self-rated depressive symptoms in a group of 132 subjects with(More)
