The Erythroblastic Island As An Emerging Paradigm In The Anemia Of Inflammation, J. Hom, B. M. Dulmovits, N. Mohandas, L. Blanc Jan 2015

The Erythroblastic Island As An Emerging Paradigm In The Anemia Of Inflammation, J. Hom, B. M. Dulmovits, N. Mohandas, L. Blanc

Journal Articles

Terminal erythroid differentiation occurs in the bone marrow, within specialized niches termed erythroblastic islands. These functional units consist of a macrophage surrounded by differentiating erythroblasts and have been described more than five decades ago, but their function in the pathophysiology of erythropoiesis has remained unclear until recently. Here we propose that the central macrophage in the erythroblastic island contributes to the pathophysiology of anemia of inflammation. After introducing erythropoiesis and the interactions between the erythroblasts and the central macrophage within the erythroblastic islands, we will discuss the immunophenotypic characterization of this specific subpopulation of macrophages. We will then integrate these …

Judging Quality Of Current Septic Shock Definitions And Criteria, M. Shankar-Hari, G. Bertolini, F. M. Brunkhorst, R. Bellomo, D. Annane, C. S. Deutschman, M. Singer Jan 2015

Judging Quality Of Current Septic Shock Definitions And Criteria, M. Shankar-Hari, G. Bertolini, F. M. Brunkhorst, R. Bellomo, D. Annane, C. S. Deutschman, M. Singer

Journal Articles

Septic shock definitions are being revisited. We assess the feasibility, reliability, and validity characteristics of the current definitions and criteria of septic shock. Septic shock is conceptualised as cardiovascular dysfunction, tissue perfusion and cellular abnormalities caused by infection. Currently, for feasibility, septic shock is identified at the bedside by using either hypotension or a proxy for tissue perfusion/cellular abnormalities (e.g., hyperlactatemia). We propose that concurrent presence of cardiovascular dysfunction and perfusion/cellular abnormalities could improve validity of septic shock diagnosis, as we are more likely to identify a patient population with all elements of the illness concept. This epidemiological refinement should …

Mutations In Ddx3x Are A Common Cause Of Unexplained Intellectual Disability With Gender-Specific Effects On Wnt Signaling, L. Snijders Blok, E. Madsen, J. Juusola, C. Gilissen, D. Baralle, M. R. Reijnders, H. Venselaar, J. Fox, J. Mclaughlin, T. Kleefstra, +73 Additional Authors

Journal Articles

Intellectual disability (ID) affects approximately 1%-3% of humans with a gender bias toward males. Previous studies have identified mutations in more than 100 genes on the X chromosome in males with ID, but there is less evidence for de novo mutations on the X chromosome causing ID in females. In this study we present 35 unique deleterious de novo mutations in DDX3X identified by whole exome sequencing in 38 females with ID and various other features including hypotonia, movement disorders, behavior problems, corpus callosum hypoplasia, and epilepsy. Based on our findings, mutations in DDX3X are one of the more common …

Assessing Cerebral Glucose Metabolism In Patients With Idiopathic Rapid Eye Movement Sleep Behavior Disorder, J. Ge, P. Wu, S. Peng, H. Yu, H. Zhang, Y. Guan, D. Eidelberg, C. Zuo, Y. L. Ma, J. Wang

Journal Articles

Idiopathic rapid eye movement sleep behavior disorder (RBD) is a risk marker for subsequent development of neurodegenerative parkinsonism. In this study, we aimed to investigate whether regional cerebral metabolism is altered in patients with RBD and whether regional metabolic activities are associated with clinical measurements in individual patients. Twenty-one patients with polysomnogram-confirmed RBD and 21 age-matched healthy controls were recruited to undertake positron emission tomography imaging with [18F]fluorodeoxyglucose. Differences in normalized regional metabolism and correlations between metabolic activity and clinical indices in RBD patients were evaluated on a voxel basis using statistic parametric mapping analysis. Compared with controls, patients with …

Effects Of Levodopa On Regional Cerebral Metabolism And Blood Flow, J. H. Ko, R. P. Lerner, D. Eidelberg Jan 2015

Effects Of Levodopa On Regional Cerebral Metabolism And Blood Flow, J. H. Ko, R. P. Lerner, D. Eidelberg

Journal Articles

Levodopa (l-dopa) has been at the forefront of antiparkinsonian therapy for a half century. Recent advances in functional brain imaging have contributed substantially to the understanding of the effects of l-dopa and other dopaminergic treatment on the activity of abnormal motor and cognitive brain circuits in Parkinson's disease patients. Progress has also been made in understanding the functional pathology of dyskinesias, a common side effect of l-dopa treatment, at both regional and network levels. Here, we review these studies, focusing mainly on the new mechanistic insights provided by metabolic brain imaging and network analysis. (c) 2014 International Parkinson and Movement …

Journal Articles

Cognitive deficits in Parkinson's disease (PD) have been associated with a specific metabolic covariance pattern. Although the expression of this PD cognition-related pattern (PDCP) correlates with neuropsychological performance, it is not known whether the PDCP topography is reproducible across PD populations. We therefore sought to identify a PDCP topography in a new sample comprised of 19 Dutch PD subjects. Network analysis of metabolic scans from these individuals revealed a significant PDCP that resembled the original network topography. Expression values for the new PDCP correlated (P = 0.001) with executive dysfunction on the Frontal Assessment Battery (FAB). Subject scores for the …

Journal Articles

Although primary dystonia is defined by its characteristic motor manifestations, non-motor signs and symptoms have increasingly been recognized in this disorder. Recent neuroimaging studies have related the motor features of primary dystonia to connectivity changes in cerebello-thalamo-cortical pathways. It is not known, however, whether the non-motor manifestations of the disorder are associated with similar circuit abnormalities. To explore this possibility, we used functional magnetic resonance imaging to study primary dystonia and healthy volunteer subjects while they performed a motion perception task in which elliptical target trajectories were visually tracked on a computer screen. Prior functional magnetic resonance imaging studies of …

Risk Factors Associated With Intracranial Hemorrhage In Neonates With Persistent Pulmonary Hypertension On Ecmo, S. Doymaz, M. Zinger, T. Sweberg Jan 2015

Risk Factors Associated With Intracranial Hemorrhage In Neonates With Persistent Pulmonary Hypertension On Ecmo, S. Doymaz, M. Zinger, T. Sweberg

Journal Articles

BACKGROUND: Up to 40% of infants with persistent pulmonary hypertension (PPHN) remains refractory to conventional therapies, and extracorporeal membrane oxygenation (ECMO) is offered as an effective support for this group. However, ECMO is a highly invasive and risky procedure with devastating complications such as intracranial hemorrhage (ICH). In this study, we aimed to determine the risk factors for ICH in infants with PPHN. METHODS: A case-control study of patients admitted to the pediatric intensive care unit (PICU) with PPHN requiring ECMO support was conducted. The study was carried out at a 25-bed PICU in large urban tertiary care children's hospital. …

Antigen-Based Immunotherapy For Autoimmune Disease: Current Status, D. L. Hirsch, P. Ponda Jan 2015

Antigen-Based Immunotherapy For Autoimmune Disease: Current Status, D. L. Hirsch, P. Ponda

Journal Articles

Autoimmune diseases are common chronic disorders that not only have a major impact on the quality of life but are also potentially life-threatening. Treatment modalities that are currently favored have conferred signifcant clinical benefts, but they may have considerable side effects. An optimal treatment strategy for autoimmune disease would specifcally target disease-associated antigens and limit systemic side effects. Similar to allergen-specifc immunotherapy for allergic rhinitis, antigen-specifc immunotherapy for autoimmune disease aims to induce immune deviation and promote tolerance to specifc antigens. In this review, we present the current status of studies and clinical trials in both human and animal hosts …

Assessing The Associations Of Sodium Intake With Long-Term All-Cause And Cardiovascular Mortality In A Hypertensive Cohort, P. Singer, H. Cohen, M. Alderman Jan 2015

Assessing The Associations Of Sodium Intake With Long-Term All-Cause And Cardiovascular Mortality In A Hypertensive Cohort, P. Singer, H. Cohen, M. Alderman

Journal Articles

BACKGROUND: Although higher sodium intake is known to increase blood pressure, its association with cardiovascular mortality is less established. We examined the association of baseline sodium intake in a hypertensive cohort with all-cause and cardiovascular mortality over a mean follow-up of 18.6 years. METHODS: Three thousand five hundred five subjects were participants in a worksite hypertension program. Sodium intake was estimated by 24-hour urine excretion. Mortality data were obtained from the U.S. National Death Index. Unadjusted and multivariable-adjusted associations between sodium quartiles (quartile I (QI) to quartile IV (QIV)) and mortality were assessed using Cox models. RESULTS: Estimated mean +/- …

Calhm1 Ion Channel Elicits Amyloid-Beta Clearance By Insulin-Degrading Enzyme In Cell Lines And In Vivo In The Mouse Brain, V. Vingtdeux, P. Chandakkar, H. Zhao, L. Blanc, S. Ruiz, P. Marambaud Jan 2015

Calhm1 Ion Channel Elicits Amyloid-Beta Clearance By Insulin-Degrading Enzyme In Cell Lines And In Vivo In The Mouse Brain, V. Vingtdeux, P. Chandakkar, H. Zhao, L. Blanc, S. Ruiz, P. Marambaud

Journal Articles

Alzheimer's disease is characterized by amyloid-beta (Abeta) peptide accumulation in the brain. CALHM1, a cell-surface Ca(2+) channel expressed in brain neurons, has anti-amyloidogenic properties in cell cultures. Here, we show that CALHM1 controls Abeta levels in vivo in the mouse brain through a previously unrecognized mechanism of regulation of Abeta clearance. Using pharmacological and genetic approaches in cell lines, we found that CALHM1 ion permeability and extracellular Ca(2+) were required for the Abeta-lowering effect of CALHM1. Abeta level reduction by CALHM1 could be explained by an increase in extracellular Abeta degradation by insulin-degrading enzyme (IDE), extracellular secretion of which was …

Journal Articles

HIV may induce gastrointestinal (GI) mucosal immune dysregulation similar to inflammation observed in ulcerative colitis (UC). Colorectal biopsies from healthy controls (N=12) and from participants with HIV (N=20) or UC (N=9) were subjected to real time (RT)-PCR for selected cytokines, chemokines, antimicrobial peptides, Toll-like receptors, and inflammatory signaling and epithelial barrier proteins. HIV long terminal repeat relative copy number (RCN) in HIV participant biopsies was quantified by RT-PCR. Mean interleukin (IL)-6 mRNA levels did not differ significantly between HIV and UC participants (p=0.48) but were significantly higher relative to control mRNA levels only for HIV participants (p=0.03). Mean IL-8 and …

ANG II type 1 receptor blockade (AT(1)R-BLK) is used extensively to slow down the progression of proteinuric kidney diseases. We hypothesized that AT(1)R-BLK provides podocyte protection through regulation of silencing mediator of retinoic acid and thyroid hormone receptor (SMRT) and vitamin D receptor (VDR) expression under adverse milieus such as high glucose and human immunodeficiency virus infection. Both AT(1)R-BLK and VDR agonists (VDAs) stimulated VDR complex formation that differed not only in their composition but also in their functionality. AT(1)R-BLK-induced VDR complexes contained predominantly unliganded VDR, SMRT, and phosphorylated histone deacetylase 3, whereas VDA-VDR complexes were constituted by liganded VDR …

Journal Articles

Kaposi Sarcoma (KS) is an angioproliferative tumor associated with human herpes virus 8 (HHV-8). Often known as one of the acquired immunodeficiency syndrome (AIDS)-defining skin diseases, pulmonary involvement in KS has only been discussed in a handful of case reports, rarely in a non-HIV patient. Herein we report the case of a 77 year-old- male who presented with a 6-week history of progressive dyspnea on exertion accompanied by productive cough of yellow sputum and intermittent hemoptysis. His past medical history was significant for Non-Hodgkin's Follicular B-Cell Lymphoma (NHL). Patient also had biopsy-confirmed cutaneous KS. His physical exam was notable for …

Clinical Markers Of Crohn's Disease Severity And Their Association With Opiate Use, M. Cheung, S. Khan, M. Akerman, C. K. Hung, K. Vennard, N. Hristis, K. Sultan Jan 2015

Clinical Markers Of Crohn's Disease Severity And Their Association With Opiate Use, M. Cheung, S. Khan, M. Akerman, C. K. Hung, K. Vennard, N. Hristis, K. Sultan

Journal Articles

BACKGROUND: The safety of opiate use for patients with Crohn's disease (CD) has long been a concern. The recent Crohn's therapy, resource, evaluation, and assessment tool (TREAT) registry update has added to these concerns by demonstrating an association of opiate use with an increased risk of infection and death in CD. While the association is clear, the relationship of opiates to these negative outcomes is not. It is unknown whether opiates are a contributing factor to these negative outcomes or if their use is merely a marker of more severe disease. We hypothesized that opiate use is not harmful in …

Innate immune receptors for pathogen- and damage-associated molecular patterns (PAMPs and DAMPs) orchestrate inflammatory responses to infection and injury. Secreted by activated immune cells or passively released by damaged cells, HMGB1 is subjected to redox modification that distinctly influences its extracellular functions. Previously, it was unknown how the TLR4 signalosome distinguished between HMGB1 isoforms. Here we demonstrate that the extracellular TLR4 adaptor, myeloid differentiation factor 2 (MD-2), binds specifically to the cytokine-inducing disulfide isoform of HMGB1, to the exclusion of other isoforms. Using MD-2-deficient mice, as well as MD-2 silencing in macrophages, we show a requirement for HMGB1-dependent TLR4 signaling. …
