We examined whether activating mu-opioid receptors (MORs) in the peripheral nervous system attenuates spinal cord injury (SCI) pain-like behavior in mice. We produced a contusive SCI at the T10 vertebral level and examined motor and sensory dysfunction for 6 weeks. At 6 weeks, we tested the effect of subcutaneous (s.c.) injection of dermorphin [D-Arg2, Lys4] (1-4) amide (DALDA), a peripherally acting MOR-preferring agonist, on mechanical and heat hypersensitivity. Basso mouse scale score was significantly decreased after SCI, and mice showed hypersensitivity to mechanical and heat stimulation at the hind paw beginning at 2...

Conclusions: In summary, our studies provide initial evidence that the LDH chronic pain model might serve as a model of the comorbidity of low back pain and depression. The finding that FLX improved depressive behavior and pain through normalized 5-HT concentrations and TNF-α mRNA expression establishes the initial mechanism of the comorbidity of pain and depression.

Publication date: Available online 6 September 2019Source: Anaesthesia &Intensive Care MedicineAuthor(s): G. Baranidharan, Ibrahim MohamedAbstractNeuropathic pain is a well-recognized chronic pain condition. This can have a significant impact in patients' quality of life. Neuromodulation is defined by the International Neuromodulation Society as ‘the therapeutic alteration of activity in the central or peripheral nervous system either electrically or pharmacologically’. Electrical stimulation can be performed at the motor cortex, deep brain, spinal cord, dorsal root ganglion, peripheral nerve and peripheral...

Complex regional pain syndrome (CRPS) type I and CRPS type II diminish quality of life and can lead to significant disability.15 Both conditions have varied and complex clinical features, with chronic debilitating pain being the primary symptom, usually involving the lower or upper extremities.16,24 The conditions are differentiated by the absence (CRPS-I) or presence (CRPS-II) of demonstrable nerve damage as an underlying etiology.

In this study, the biological effects and mechanisms of RACK1 contributes to the pathogenesis of chronic constriction injury (CCI)-induced neuropathic pain were investigated. By western blot and staining, we found that RACK1 protein changed in dorsal root ganglion (DRG) neurons and spinal cord (SC) neurons except glial cells after CCI. Especially, RACK1 was co-located with IB4-, CGRP-positive neurons, suggesting it was related to integrate nociceptive information from the primary afferents in DRG. The successful establishment of CCI models also directly led to mechanical allodynia and heat hyperalgesia, which could be rev...

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined. Mean nonfasting cholesterol concentration was 72...

In conclusion, with study of the frailty syndrome still in its infancy, frailty analysis remains a major challenge. It is a challenge that needs to be overcome in order to shed light on the multiple mechanisms involved in the pathogenesis of this syndrome. Although several mechanisms contribute to frailty, immune system alteration seems to play a central role: this syndrome is characterized by increased levels of pro-inflammatory markers and the resulting pro-inflammatory status can have negative effects on various organs. Future studies should aim to better clarify the immune system alteration in frailty, and seek to esta...

This study, when complete, will be a monumental step-up for evidence-driven medicine in the rapidly growing field of neuromodulation,” said Andrea Trescot, the CMO of Stimwave and former President of the American Society of Interventional Pain Physicians (ASIPP). “Every other industry is expected to show efficacy through sham and placebo-controlled studies; the Tsunami study is growing the evidence that single-stage, wireless neurostimulators can offer more options to more pain patients.” Medtech's Response The opioid crisis has had a profound impact in the U.S. resulti...
