OBJECTIVES: To assess the clinical validity and factor structure of the Fear-Avoidance Components Scale (FACS), a new fear-avoidance (FA) measure. METHODS: In this study, 426 chronic musculoskeletal pain disorder (CMPD) patients were admitted to a functional restoration program (FRP). They were categorized into five FACS severity levels, from Subclinical to Extreme, at admission, and again at discharge. Associations with objective lifting performance and other patient-reported psychosocial measures were determined at admission and discharge, and objective work outcomes for this predominantly disabled cohort, were assessed one-year later...

Increased prescribing of opioids for chronic non cancer pain is associated with significant social costs, including overdose and addiction. In this context, there is interest in interdisciplinary chronic pain rehabilitation programs (ICPRP) focusing on self-management and minimizing opioid use. This study examined outcomes of patients weaned from opioids in an ICPRP from 2007-2012. Participants included 413 patients on high dose (HD) chronic opioid therapy (COT; >100mg), 528 on low dose (LD) COT and 516 not on opioids (NO)...

Millions of patients benefit from surgery and are exposed to surgical stress. However, ample studies suggest that surgical stress contributes to tumor recurrence or distant metastases. Surgical stress suppresses CD8+ T cells (CTL) function which is vital for eliminating the malignant cells. Anti-programmed cell death 1 (PD-1) therapy is an effective and safe treatment that increases survival rate of patients with multiple cancers, however, whether anti-PD-1 therapy is able to reverse the immunosuppression following surgery remains largely unknown...

INTRODUCTION: The U.S. Army Comprehensive Pain Management Campaign Plan was launched in 2010 to improve pain outcomes in military populations. Interdisciplinary Pain Management Centers (IPMCs) were established at every Army medical center, each offering a robust array of treatment options including conventional and complementary and integrative medicine (CIM) pain management therapies. The Pain Assessment Screening Tool and Outcomes Registry (PASTOR) was developed to assess and track biopsychosocial aspects of pain management and to identify best treatment practices...

Malignant pleural effusions are frequent in patients with advanced stages of lung cancer and are commonly infiltrated by lymphocytes and tumor cells. CD8+ T cells from these effusions have reduced effector functions. The programmed death receptor 1(PD-1)/programmed death ligand 1 (PD-L1) pathway is involved in T-cell exhaustion, and it might be responsible for T-cell dysfunction in lung cancer patients. Here, we show that PD-L1 is expressed on tumor cell samples from malignant effusions, on lung cancer cell lines, and, interestingly, on MRC-5 lung fibroblasts...

BACKGROUND: Cochlear implants (CIs) successfully restore hearing in postlingually deaf adults, but in doing so impose a frequency-position function in the cochlea that may differ from the physiological one. PURPOSE: The CI-imposed frequency-position function is determined by the frequency allocation table programmed into the listener's speech processor and by the location of the electrode array along the cochlea. To what extent can postlingually deaf CI users successfully adapt to the difference between physiological and CI-imposed frequency-position functions? RESEARCH DESIGN: We attempt to answer the question by combining behavioral measures of electroacoustic pitch matching (PM) and measures of electrode location within the cochlea...

Mitochondrial function is central to many different processes in the cell, from oxidative phosphorylation to the synthesis of iron-sulfur clusters. Therefore, mitochondrial dysfunction underlies a diverse array of diseases, from neurodegenerative diseases to cancer. Stress can be communicated to the cytosol and nucleus from the mitochondria through many different signals, and in response the cell can effect everything from transcriptional to post-transcriptional responses to protect the mitochondrial network...

In a subset of children experiencing prolonged febrile seizures (FS), the most common type of childhood seizures, cognitive outcomes are compromised. However, the underlying mechanisms are unknown. Here we identified significant, enduring spatial memory problems in male rats following experimental prolonged FS (febrile status epilepticus; eFSE). Remarkably, these deficits were abolished by transient, post hoc interference with the chromatin binding of the transcriptional repressor neuron restrictive silencing factor (NRSF or REST)...

REVIEW
Donna Bloodworth, Sindhu Pandit, Patrick Mullan, Faye C Tan
Rehabilitation Traumatology has developed within Physical Medicine and Rehabilitation as a specialized area of knowledge in which the physiatrist works with the Traumatology team to enhance the functional outcome of trauma patients. The American Heritage Dictionary defines Traumatology as "the branch of medicine that deals with the treatment of serious wounds, injuries, and disabilities" [1]. It defines rehabilitate as "to restore to good health or useful life, as through therapy and education" [1]. Thus the authors propose Rehabilitation Traumatology be "the branch of medicine that deals with the treatment of serious wounds, injuries, and disabilities", "to restore (the patient) to good health or useful life"...

BACKGROUND AND PURPOSE: The outcome for older stroke patients who undergo endovascular revascularization remains unsatisfactory. We aimed to determine the effect of the extent of baseline ischemia on outcome according to age, testing the hypothesis that the restorative capacity for recovery is only marginal in older patients. METHODS: Two hundred and thirteen patients who underwent endovascular revascularization due to occlusion in the M1 segment of the middle cerebral artery (with or without internal carotid artery occlusions) were selected for analysis...

Flaviviral infections including dengue virus are an increasing clinical problem worldwide. Dengue infection triggers host production of the type 1 IFN, IFN alpha, one of the strongest and broadest acting antivirals known. However, dengue virus subverts host IFN signaling at early steps of IFN signal transduction. This subversion allows unbridled viral replication which subsequently triggers ongoing production of IFN which, again, is subverted. Identification of downstream IFN antiviral effectors will provide targets which could be activated to restore broad acting antiviral activity, stopping the signal to produce endogenous IFN at toxic levels...

The Programmed Death-1 (PD-1) receptor delivers inhibitory checkpoint signals to activated T cells upon binding to its ligands PD-L1 and PD-L2 expressed on antigen presenting cells and cancer cells, resulting in suppression of T cell effector function and tumor immune evasion. Clinical antibodies blocking the interaction between PD-1 and PD-L1 restore the cytotoxic function of tumor antigen-specific T cells, yielding durable objective responses in multiple cancers. This report describes the preclinical characterization of REGN2810, a fully human hinge-stabilized IgG4 (S228P) high-affinity anti-PD-1 antibody that potently blocks PD-1 interactions with PD-L1 and PD-L2...

The inner ear is a complex vertebrate sense organ, yet arises from a simple epithelium, the otic placode. Specification towards otic fate requires diverse signals and transcriptional inputs that act sequentially and/or in parallel. Using the chick embryo, we uncover novel genes in the gene regulatory network underlying otic commitment and reveal dynamic changes in gene expression. Functional analysis of selected transcription factors reveals the genetic hierarchy underlying the transition from progenitor to committed precursor, integrating known and novel molecular players...

Conversion of fibroblasts into functional cardiomyocytes represents a potential means of restoring cardiac function after myocardial infarction, but so far this process remains inefficient and little is known about its molecular mechanisms. Here we show that DAPT, a classical Notch inhibitor, enhances the conversion of mouse fibroblasts into induced cardiac-like myocytes by the transcription factors GATA4, HAND2, MEF2C, and TBX5. DAPT cooperates with AKT kinase to further augment this process, resulting in up to 70% conversion efficiency...

AIM: Alteration of functional beta-cell mass in adults can be programmed by adverse events during fetal life. Previously, it was demonstrated that high glucocorticoid (GC) levels during fetal life participate in this programming by inhibition of beta-cell development. More specifically, GC levels stimulate expression of peroxisome proliferator-activated receptor-gamma coactivator 1-alpha (PGC-1α), a transcriptional co-regulator of the GC receptor (GR), which per se impairs beta-cell mass and function when overexpressed...

BACKGROUND: Death after withdrawal of mechanical ventilation frequently follows the sequence of progressive hypoxemia and hypotension leading to cardiac arrest. Accurate timing of the determination of death is fundamental to trust in controlled donation after circulatory death (cDCD) programs and is generally based on cessation of circulation (pulselessness), brain function (apnea), and the passage of time. If death is understood to be the unresuscitatable loss of brain function, the clinical determination that death following apnea and pulselessness has occurred is largely inferential...

Perinatal hypoxia severely disrupts metabolic and somatotrophic development, as well as cerebral maturational programs. Hypoxia-inducible transcription factors (HIF) represent the most important endogenous adaptive mechanisms to hypoxia, activating a broad spectrum of growth factors that contribute to cell survival and energy homeostasis. To analyse effects of systemic hypoxia and growth hormone (GH) therapy (rhGH) on HIF-dependent growth factors during early postnatal development, we compared protein (ELISA) and mRNA levels (quantitative RT PCR) of growth factors in plasma and brain between normoxic and hypoxic mice (8% O2, 6 h; postnatal day 7, P7) at P14...

BACKGROUND: Movement asymmetries during walking are common after anterior cruciate ligament (ACL) injury and reconstruction and may influence the early development of posttraumatic osteoarthritis. Preoperative neuromuscular training (like perturbation training, which is neuromuscular training requiring selective muscle activation in response to surface perturbations) improves gait asymmetries and functional outcomes among people who are ACL-deficient, but the effect of postoperative perturbation training on gait mechanics after ACL reconstruction is unknown...
