RESUMO
ABSTRACT: Chronic pain affects more than 50 million Americans. Treatments remain inadequate, in large part, because the pathophysiological mechanisms underlying the development of chronic pain remain poorly understood. Pain biomarkers could potentially identify and measure biological pathways and phenotypical expressions that are altered by pain, provide insight into biological treatment targets, and help identify at-risk patients who might benefit from early intervention. Biomarkers are used to diagnose, track, and treat other diseases, but no validated clinical biomarkers exist yet for chronic pain. To address this problem, the National Institutes of Health Common Fund launched the Acute to Chronic Pain Signatures (A2CPS) program to evaluate candidate biomarkers, develop them into biosignatures, and discover novel biomarkers for chronification of pain after surgery. This article discusses candidate biomarkers identified by A2CPS for evaluation, including genomic, proteomic, metabolomic, lipidomic, neuroimaging, psychophysical, psychological, and behavioral measures. Acute to Chronic Pain Signatures will provide the most comprehensive investigation of biomarkers for the transition to chronic postsurgical pain undertaken to date. Data and analytic resources generatedby A2CPS will be shared with the scientific community in hopes that other investigators will extract valuable insights beyond A2CPS's initial findings. This article will review the identified biomarkers and rationale for including them, the current state of the science on biomarkers of the transition from acute to chronic pain, gaps in the literature, and how A2CPS will address these gaps.

Biomedical research training has undergone considerable change over the past several years. At its core, the goal of graduate and postdoctoral training is to provide individuals with the skills and knowledge to become outstanding scientists and expand knowledge through the scientific method. Historically, graduate school training has focused on preparation for academic positions. Increasingly, however, a shift toward preparation for a wider range of career options has emerged. This is largely because most biomedical PhD graduates do not become Principal Investigators in academic laboratories. Here we describe an National Institutes of Health Common Fund program with the major goal of culture change for biomedical research training and training that prepares individuals for a broader expanse of careers in the biomedical research enterprise. These "Broadening Experiences in Scientific Training" (BEST) awards, issued in 2012 and 2013, provided support to institutions to develop innovative approaches to achieving these goals, as a complement to traditional training. Awardees were tasked with catalyzing change at their institutions and sharing best practices across the training community. Awardees were required to participate in a cross-site evaluation that assessed the impact of BEST activities on three main areas: (a) trainee confidence and knowledge to make career decisions, (b) influence of this added activity on time in training, and (c) ability of the institutions to sustain activities deemed to be beneficial. Here we present the fundamental approach to the BEST program and early evaluative data.

The Extracellular RNA (exRNA) Communication Consortium, funded as an initiative of the NIH Common Fund, represents a consortium of investigators assembled to address the critical issues in the exRNA research arena. The overarching goal is to generate a multi-component community resource for sharing fundamental scientific discoveries, protocols, and innovative tools and technologies. The key initiatives include (a) generating a reference catalogue of exRNAs present in body fluids of normal healthy individuals that would facilitate disease diagnosis and therapies, (b) defining the fundamental principles of exRNA biogenesis, distribution, uptake, and function, as well as development of molecular tools, technologies, and imaging modalities to enable these studies,
