ReviewNovel Therapeutic Approaches in Connective Tissue Disease-Associated Interstitial Lung Disease.
Connective tissue diseases (CTD) comprise a group of autoimmune diseases that can affect multiple organs in the body including the lungs. The most common form of pulmonary involvement is interstitial lung disease (ILD). CTD-associated ILD (CTD-ILD) can take one of several courses including nonprogressive, chronically progressive, or rapidly progressive. ⋯ Limited randomized controlled trial data are available for treatment of CTD-ILD, with most data coming from systemic sclerosis-related ILD. The current first-line treatment for all CTD-ILD is immunosuppression with consideration of antifibrotics, stem cell transplant, and lung transplant in progressive disease. In this article, we review data for ILD treatment options in systemic sclerosis, rheumatoid arthritis, myositis, and primary Sjögren's syndrome-related ILDs.

To identify chronic pain management strategies aimed to reduce pain intensity and enhance functional outcomes in veterans of wars and armed conflict. ⋯ Nonpharmacological treatments for chronic pain have increased in recent years, a shift from earlier reliance on pharmacological treatments. More evidence from randomized controlled trials on the benefits of combined pain interventions could improve pain management of veterans with complex care needs.

Productivity loss because of chronic pain in the working age population is a widespread concern internationally. Interventions for chronic pain in working age adults might be expected to achieve enhanced productivity in terms of reduced costs of workers' compensation insurance, reduced disability support, and improved rates of return to work for injured workers. This would require the use of measures of productivity in the evaluation of chronic pain management interventions. ⋯ Ten studies found no statistically significant improvements in productivity-related costs. Despite evidence for reduced pain-related disability after pain management interventions, this review suggests that the use of measures for assessing productivity gains is lacking. Including such measures would greatly assist administrators and payers when considering the broader societal benefits of such interventions.

The dorsal reticular nucleus is a pain facilitatory area involved in diffuse noxious inhibitory control (DNIC) through opioidergic mechanisms that are poorly understood. The hypothesis was that signaling of μ-opioid receptors is altered in this area with prolonged chronic inflammatory pain and that this accounts for the loss of DNICs occurring in this condition. ⋯ The dorsal reticular nucleus is likely involved in a facilitatory pathway responsible for DNIC hyperalgesia. The shift of μ-opioid receptor signaling to excitatory in this pathway likely accounts for the loss of DNIC analgesia in monoarthritis.

Quercetin, Main Active Ingredient of Moutan Cortex, Alleviates Chronic Orofacial Pain via Block of Voltage-Gated Sodium Channel.
Chronic orofacial pain (COP) therapy is challenging, as current medical treatments are extremely lacking. Moutan Cortex (MC) is a traditional Chinese medicine herb widely used for chronic inflammatory diseases. However, the mechanism behind MC in COP therapy has not been well-established. The purpose of this study was to identify the active ingredients of MC and their specific underlying mechanisms in COP treatment. ⋯ Identifying Na v as the molecular target of quercetin clarifies the analgesic mechanism of MC, and provides ideas for the development of novel selective and efficient chronic pain relievers.
