Fibromyalgia (FM) is a common and often debilitating chronic pain condition. Research shows that symptoms of depression and anxiety are present in up to three quarters of individuals with FM. Of concern, most adults with FM cannot access traditional face-to-face cognitive behavioural pain management programs, which are known to be beneficial. ⋯ The changes were maintained at four-week follow-up. The current findings add to existing literature and highlight the specific potential of Internet-delivered cognitive behavioural pain management programs for adults with FM, especially as a part of stepped-care models of care. Future research directions are described.

The melanocortin 4 receptor (MC4R) is a G protein-coupled receptor (GPCR) that is expressed in several brain nuclei playing a crucial role in the regulation of energy balance controlling the homeostasis of the organism. It displays both agonist-evoked and constitutive activity, and moreover, it can couple to different G proteins. Most of the research on MC4R has been focused on agonist-induced activity, while the molecular and cellular basis of MC4R constitutive activity remains scarcely studied. ⋯ We also explored the signaling pathways mediating this inhibition, and thus propose that agonist-dependent and basal MC4R activation modes signal differentially through Gs and Gi/o pathways to impact on different CaV subtypes. In addition, we found that chronic incubation with MC4R endogenous inverse agonist, agouti and agouti-related peptide (AgRP), occludes CaV inhibition in a cell line and in amygdaloid complex cultured neurons as well. Thus, we define new mechanisms of control of the main mediators of depolarization-induced calcium entry into neurons by a GPCR that displays constitutive activity.

Multicenter StudyA New Approach for Identifying Patients with Undiagnosed Chronic Obstructive Pulmonary Disease.
Chronic obstructive pulmonary disease (COPD) is often unrecognized and untreated. ⋯ CAPTURE with PEF can identify patients with COPD who would benefit from currently available therapy and require further diagnostic evaluation. Clinical trial registered with clinicaltrials.gov (NCT01880177).
