Does the addition of whole-body MRI to routine imaging influence real-world treatment decisions in metastatic breast cancer?

Background: The assessment of metastatic breast cancer (MBC) can be limited with routine imaging such as computed tomography (CT) especially in bone-only or bone-predominant disease. This analysis investigates the effects of the use of WBMRI in addition to the use of routine CT, bone scintigraphy (BS) and fluorine-18-fluorodeoxyglucose positron emission tomography with computed tomography (FDG-PET/CT) on influencing systemic anti-cancer treatment (SACT) decisions in patients with known MBC.

Methods: MBC patients undergoing SACT who had WBMRI undertaken within 8 weeks of either a routine CT, BS or FDG-PET/CT were reviewed retrospectively.

Lung Parenchymal and Tracheal CT Morphology: Evaluation before and after Bariatric Surgery.

Background There is significant pulmonary functional deficit related to obesity, but no prospective CT studies have evaluated the effects of obesity on the lungs and trachea. Purpose To evaluate lung parenchymal and tracheal CT morphology before and 6 months after bariatric surgery, with functional and symptomatic correlation. Materials and Methods A prospective longitudinal study of 51 consecutive individuals referred for bariatric surgery was performed (from November 2011 to November 2013).

Effects of cannabinoids on capsaicin receptor activity following exposure of primary sensory neurons to inflammatory mediators.

Aims: Activation of the cannabinoid 1 (CB1) receptor in cultured primary sensory neurons reduces responses mediated through the transient receptor potential vanilloid type 1 receptor (TRPV1), which plays a pivotal role in the development of heat hyperalgesia and visceral hyper-reflexia in inflammatory conditions. Here, we studied the effect of cannabinoid-evoked inhibitory effect on TRPV1 in inflammatory conditions.

Main Methods: The effect of anandamide (1 nM-30 nM) and 1,1-dimethylheptyl-11-hydroxytetrahydrocannabinol (HU210; 1 microM-10 microM) was assessed on capsaicin (10 nM or 100 nM)-evoked cobalt uptake in rat cultured primary sensory neurons following the incubation of the cells in an "inflammatory environment" created by the major inflammatory mediators, bradykinin (5 microM), prostaglandin E(2) (5 microM) and nerve growth factor (100 ng/ml) for 10 min.
