Use of Oral Anticoagulation in the Management of Atrial Fibrillation in Patients with ESRD: Pro.
Warfarin has had a thin margin of benefit over risk for the prevention of stroke and systemic embolism in patients with ESRD because of higher bleeding risks and complications of therapy. The successful use of warfarin has been dependent on the selection of patients with nonvalvular atrial fibrillation at relatively high risk of stroke and systemic embolism and lower risks of bleeding over the course of therapy. Without such selection strategies, broad use of warfarin has not proven to be beneficial to the broad population of patients with ESRD and nonvalvular atrial fibrillation. ⋯ Clinical data for ESRD are limited, because pivotal trials excluded such patients. Given the very high risk of stroke and systemic embolism and the early evidence of acceptable safety profiles of novel oral anticoagulants, we think that patients with ESRD should be considered for treatment with chronic anticoagulation provided that there is an acceptable bleeding profile. Apixaban is currently indicated in ESRD for this application and may be preferable to warfarin given the body of evidence for warfarin and its difficulty of use and attendant adverse events.

Adults with mood disorders frequently use prescription opioids. The factors associated with this increased use remain unclear. We used the Medical Expenditure Panel Surveys from 2005 to 2011 to measure the association of mood disorders with new opioid use and the transition to longer-term opioid use for a variety of pain conditions before and after controlling for patient characteristics and clinical disability. ⋯ After adjusting for sociodemographics and clinical disability, there was no association between mood disorders and new opioid use for likely acute (adjusted odds ratio [aOR] 1.05 [0.92-1.20]) or potentially chronic pain (aOR 0.91 [0.80-1.03]). However, there remained a strong association between mood disorders and the transition to longer-term opioid use for likely acute (aOR 1.77 [1.15-2.72]) and potentially chronic pain (aOR 1.95 [1.42-2.68]). Targeting the transition to longer-term opioid use may help clinicians reduce potentially inappropriate opioid prescriptions in this high-risk population.

Fibromyalgia syndrome (FMS) is a chronic widespread pain condition probably comprising subgroups with different underlying pathomechanisms. There is increasing evidence for small nerve fiber impairment in subgroups of patients with FMS. MicroRNAs (miRNAs) regulate molecular factors determining nerve de- and re-generation. ⋯ We found 51 aberrantly expressed miRNAs in white blood cells of patients with FMS, of which miR-let-7d correlated with reduced small nerve fiber density in patients with FMS. Furthermore, we demonstrated miR-let-7d and its downstream target insulin-like growth factor-1 receptor as being aberrantly expressed in skin of patients with FMS with small nerve fiber impairment. Our study gives further evidence of small nerve fiber pathology in FMS subgroups and provides a missing link in the pathomechanism that may lead to small fiber loss in subgroups of patients with FMS.
