Anesthesia and analgesia · Mar 2014
The endocannabinoid anandamide inhibits voltage-gated sodium channels nav1.2, nav1.6, nav1.7, and nav1.8 in Xenopus oocytes.
Anandamide is an endocannabinoid that regulates multiple physiological functions by pharmacological actions, in a manner similar to marijuana. Recently, much attention has been paid to the analgesic effect of endocannabinoids in terms of identifying new pharmacotherapies for refractory pain management, but the mechanisms of the analgesic effects of anandamide are still obscure. Voltage-gated sodium channels are believed to play important roles in inflammatory and neuropathic pain. We investigated the effects of anandamide on 4 neuronal sodium channel α subunits, Nav1.2, Nav1.6, Nav1.7, and Nav1.8, to explore the mechanisms underlying the antinociceptive effects of anandamide. ⋯ Anandamide inhibited the function of α subunits in neuronal sodium channels Nav1.2, Nav1.6, Nav1.7, and Nav1.8. These results help clarify the mechanisms of the analgesic effects of anandamide.

Randomized Controlled Trial Multicenter Study
Neurobehavioral Functioning and Survival Following Lung Transplantation.
Neurobehavioral functioning is widely recognized as being an important consideration in lung transplant candidates, but little is known about whether these factors are related to clinical outcomes. The present study examined the relationship of neurobehavioral functioning, including measures of executive function and memory, depression, and anxiety, to long-term survival among lung transplant recipients. ⋯ Neurobehavioral functioning, including persistently elevated depressive symptoms and lower neurocognitive performance, was associated with reduced survival after lung transplantation.

Multicenter Study
Predicting Pulmonary Fibrosis Disease Course from Past Trends in Pulmonary Function.
The clinical course of idiopathic pulmonary fibrosis (IPF) is characterized by progressive decline in lung function and eventual mortality. We sought to determine if future declines in pulmonary function, mortality, or both can be predicted from prior trends in pulmonary function tests (PFTs). ⋯ PFT decline predicts early mortality, but not future declines in physiology, regardless of time since diagnosis.

COPD QVA149 PostersSESSION TYPE: Poster PresentationsPRESENTED ON: Saturday, March 22, 2014 at 01:15 PM - 02:15 PMPURPOSE: The current GOLD strategy recommends combining two long-acting bronchodilators for the maintenance treatment of patients with moderate-to-severe COPD. The SHINE study evaluated the effect of QVA149, a dual bronchodilator combining the LABA indacaterol and the LAMA glycopyrronium (NVA237), compared with glycopyrronium, indacaterol, tiotropium monotherapies and placebo. ⋯ Kenneth Chapman: Consultant fee, speaker bureau, advisory committee, etc.: "KRC holds the GSK-CIHR Research Chair in Respiratory Healthcare Delivery at the University Health Network, has served as a consultant to CSL Behring, GlaxoSmithKline, Novartis, Nycomed (Takeda), and Talecris (Grifols), and has received payment for lectures or service on speakers bureaus from Boehringer-Ingelheim, GlaxoSmithKline, Grifols, Nycomed (Takeda), Family Physicians Airways Group of Canada, Canadian Network for Respiratory Care, and Talecris.
