A clinician-centred programme for behaviour change in the optimal use of staging investigations for newly diagnosed prostate cancer.

Objectives: To improve imaging utilisation and reduce the widespread overuse of staging investigations, in the form of computed tomography (CT) and whole-body bone scans for men with newly diagnosed prostate cancer in the Hunter region of NSW, Australia, by implementation of a multifaceted clinician-centred behaviour change programme.

Patients And Methods: Records of all patients with a new diagnosis of prostate cancer were reviewed prior to the intervention (July 2014 to July 2015), and the results of this audit were presented to participating urologists by a clinical champion. Urologists then underwent focused education based on current guidelines.

Prostate-Specific Membrane Antigen Positron Emission Tomography-Computed Tomography for Prostate Cancer: Distribution of Disease and Implications for Radiation Therapy Planning.

Purpose: To explore the prostate-specific membrane antigen (PSMA)-avid distribution of prostate cancer (PC) on positron emission tomography (PET), both at the time of initial diagnosis and at the time of relapse after definitive local treatment.

Methods And Materials: A total of 179 PSMA PET scans in patients with nil or ≤3 lesions on conventional imaging were retrospectively categorized into 3 subgroups: group A, high-risk PC with no prior definitive therapy (n=34); group B, prior prostatectomy (n=75); and group C, prior radiation therapy (n=70). The numbers and locations of the PSMA-avid lesions were mapped.

Spinal multiparametric MRI and DEXA changes over time in men with prostate cancer treated with androgen deprivation therapy: a potential imaging biomarker of treatment toxicity.

Objectives: To explore changes in bone mineral density (BMD) measured by DEXA and MRS fat fraction (FF), Dixon FF, and ADC in lower spinal vertebral bodies in men with prostate cancer treated with androgen deprivation therapy (ADT).

Methods: Twenty-eight men were enrolled onto a clinical trial. All received ADT.

Abdominal wall infected ischemic necrosis mimicking necrotizing fasciitis.

Emergency surgery to revascularize an ischemic leg in the presence of an aortic aneurysm presents a series of difficult management decisions in both the operative and postoperative phases. We present a case of infected ischemic necrosis that developed in a discrete tissue plane from a transverse incision mimicking necrotizing fasciitis. A 57-year-old man presented with an ischemic leg associated with a 5-cm abdominal aortic aneurysm.

The effect of different enzymes on the quality of high-fibre enriched brewer's spent grain breads.

The brewing industry produces large quantities of waste co-products. There is increasing pressure to ensure total utilisation of such products to address economic and environmental concerns. Brewer's spent grain (BSG) the main by-product of the brewing industry is rich in dietary fibre and has a strong potential to be recycled.

Determination of added fat in meat paste using microwave and millimetre wave techniques.

By evaluating the sensitivity of measurement parameters such as dielectric constant and microwave loss to fat content, several microwave and millimetre methods were compared to identify optimal frequency measurement bands. The results showed that the optimum frequency range lay between 8 and 20GHz where these parameters vary linearly, by up to a factor of 8, as fat is increased to 50% volume. A narrowband waveguide sensor cell was designed and constructed for this optimum range.

Physical evaluation of a maize-based extruded snack with curry powder.

Response surface methodology was used to analyze the effect of screw speed (200-280 rpm), feed moisture (13.0-17.0%, wet basis), and curry powder (6.

Lost bits: particle shedding with polyvinyl chloride intravenous administration sets.

Silicone particles have been demonstrated in the effluent from silicone intravenous (IV) tubing. It has been widely suspected that polyvinyl chloride (PVC) particles are also lost. We sought to clarify the situation in a carefully controlled laboratory setting using the apparatus and flow rates common in a paediatric setting, using scanning electron microscope techniques (SEM), we found that particles were indeed shed from IV tubing during use, but they were not PVC.
