The aim of this study was to examine whether increases in severity of subclinical inflammation, measured by high-sensitivity C-reactive protein (hs-CRP), increased experimental pain sensitivity, measured by cold-pressor tolerance, and to test whether this relationship is independent of chronic pain. A large population-based study from 2007 to 2008, the sixth Tromsø Study, provided data from 12,981 participants. For the present analysis, complete data for 10,274 participants (age: median 58 years) were available. ⋯ Higher levels of hs-CRP were negatively related to cold-pressor tolerance (hazard ratio [HR] = 1.24, 95% confidence interval [CI], 1.12-1.37, P < 0.001), adjusted for age and sex. This relationship remained essentially unaltered after controlling for potential confounders (HR = 1.22, 95% CI, 1.09-1.36, P < 0.001), as well as for the presence of chronic pain (HR = 1.22, 95% CI, 1.09-1.36, P < 0.001). The present data show that subclinical inflammation is related to increased pain sensitivity, suggesting a potential role of inflammation in experimental pain which may be of importance for the development of clinical pain.

ReviewCould MRI Be Used To Image Kidney Fibrosis? A Review of Recent Advances and Remaining Barriers.
A key contributor to the progression of nearly all forms of CKD is fibrosis, a largely irreversible process that drives further kidney injury. Despite its importance, clinicians currently have no means of noninvasively assessing renal scar, and thus have historically relied on percutaneous renal biopsy to assess fibrotic burden. ⋯ Recent advances in imaging technology have raised the exciting possibility of magnetic resonance imaging (MRI)-based renal scar analysis, by capitalizing on the differing physical features of fibrotic and nonfibrotic tissue. In this review, we describe two key fibrosis-induced pathologic changes (capillary loss and kidney stiffening) that can be imaged by MRI techniques, and the potential for these new MRI-based technologies to noninvasively image renal scar.

Randomized Controlled Trial Multicenter Study
Safety and efficacy of erenumab for preventive treatment of chronic migraine: a randomised, double-blind, placebo-controlled phase 2 trial.
The calcitonin gene-related peptide (CGRP) pathway is important in migraine pathophysiology. We assessed the efficacy and safety of erenumab, a fully human monoclonal antibody against the CGRP receptor, in patients with chronic migraine. ⋯ Amgen.
