Journal Articles

Fulminant hepatic failure (FHF) is a devastating syndrome, which sometimes results in death or liver transplantation, in which inflammation would aggravate the development of fetuin-A which would act as an anti-inflammatory factor and may be an available approach to attenuate FHF. The purpose of this study was to investigate the effects of fetuin-A on d-galactosamine/lipopolysaccharide (d-GalN/LPS)-induced liver failure in mice. A mouse model of FHF induced by d-GalN/LPS was established and fetuin-A was injected intraperitoneally prior to d-GalN/LPS treatment. At different time points after d-GalN/LPS intervention, serum TNF-alpha and IL-6 levels were measured by ELISA. Fetuin-A mRNA and protein expression …

Can Newly Developed, Rapid Immunochromatographic Antigen Detection Tests Be Reliably Used For The Laboratory Diagnosis Of Influenza Virus Infections?, J. J. Dunn, C. C. Ginocchio Jan 2014

Can Newly Developed, Rapid Immunochromatographic Antigen Detection Tests Be Reliably Used For The Laboratory Diagnosis Of Influenza Virus Infections?, J. J. Dunn, C. C. Ginocchio

Journal Articles

Five years ago, the Point-Counterpoint series was launched. The initial article asked about the role of rapid immunochromatographic antigen testing in diagnosis of influenza A virus 2009 H1N1 infection (1). Since that article, major changes have been made not only in immunochromatographic antigen detection (IAD) test for the influenza viruses but there also has been rapid development of commercially available nucleic acid amplification tests (NAATs) for influenza virus detection as well. Further, a novel variant of influenza A, H7N9, has emerged in Asia and H5N1 is also re-emergent. In this initial article, the editor of this series, Peter Gilligan, identified …

Sinusoidal Obstruction Syndrome (Hepatic Veno-Occlusive Disease), C. Q. Fan, J. M. Crawford Jan 2014

Sinusoidal Obstruction Syndrome (Hepatic Veno-Occlusive Disease), C. Q. Fan, J. M. Crawford

Journal Articles

Hepatic sinusoidal obstruction syndrome (SOS) is an obliterative venulitis of the terminal hepatic venules, which in its more severe forms imparts a high risk of mortality. SOS, also known as veno-occlusive disease (VOD), occurs as a result of cytoreductive therapy prior to hematopoietic stem cell transplantation (HSCT), following oxaliplatin-containing adjuvant or neoadjuvant chemotherapy for colorectal carcinoma metastatic to the liver and treated by partial hepatectomy, in patients taking pyrrolizidine alkaloid-containing herbal remedies, and in other particular settings such as the autosomal recessive condition of veno-occlusive disease with immunodeficiency (VODI). A central pathogenic event is toxic destruction of hepatic sinusoidal endothelial …

Clozapine-Induced Agranulocytosis Is Associated With Rare Hla-Dqb1 And Hla-B Alleles, J. I. Goldstein, L. F. Jarskog, C. Hilliard, A. Alfirevic, H. L. Huang, M. Lek, A. L. Holden, D. L. Kelly, A. K. Malhotra, P. F. Sullivan, +21 Additional Authors

Journal Articles

Clozapine is a particularly effective antipsychotic medication but its use is curtailed by the risk of clozapine-induced agranulocytosis/granulocytopenia (CIAG), a severe adverse drug reaction occurring in up to 1% of treated individuals. Identifying genetic risk factors for CIAG could enable safer and more widespread use of clozapine. Here we perform the largest and most comprehensive genetic study of CIAG to date by interrogating 163 cases using genomewide genotyping and whole-exome sequencing. We find that two loci in the major histocompatibility complex are independently associated with CIAG: a single amino acid in HLA-DQB1 (126Q) (P = 4.7 x 10(-14), odds ratio …

Sudden Unexpected Death In Schizophrenia: Autopsy Findings In Psychiatric Inpatients, P. Ifteni, C. U. Correll, V. Burtea, J. M. Kane, P. Manu Jan 2014

Sudden Unexpected Death In Schizophrenia: Autopsy Findings In Psychiatric Inpatients, P. Ifteni, C. U. Correll, V. Burtea, J. M. Kane, P. Manu

Journal Articles

Schizophrenia is associated with premature mortality and a high rate of sudden, unexpected deaths. Autopsy data are scant, and in studies using death certificates or root cause assessments, a majority of sudden deaths remained unexplained. In the community, post-mortem data indicate that the most common cause of sudden "natural" death is coronary artery disease. In this study, we used autopsy findings to determine the cause of sudden death in a consecutive cohort of 7189 schizophrenia patients admitted to a free-standing, psychiatric teaching hospital from 1989 to 2013. Medical record review identified 57 patients (0.79%) who died suddenly and unexpectedly during …

Schizophrenia Relapse After Stopping Olanzapine Treatment During Pregnancy: A Case Report, P. Ifteni, M. A. Moga, V. Burtea, C. U. Correll

Journal Articles

Women with schizophrenia have a high risk for symptom exacerbation or relapse during pregnancy and thereafter. Relapses are more frequent when antipsychotics are discontinued. This paper describes the case of a 28-year old woman with schizophrenia who continued treatment with olanzapine during the first trimester. Olanzapine, a second-generation antipsychotic, was administered at a therapeutic dose from week 1 of gestation until week 13 when she reported the pregnancy to her psychiatrist. Despite the psychiatrist's recommendation to continue treatment, the patient stopped olanzapine at 20 weeks. She was hospitalized at week 36 for a schizophrenia relapse and was transferred to the …

Altered White Matter Microstructure Is Associated With Social Cognition And Psychotic Symptoms In 22q11.2 Microdeletion Syndrome, M. Jalbrzikowski, J. E. Villalon-Reina, K. H. Karlsgodt, D. Senturk, C. Chow, P. M. Thompson, C. E. Bearden

Journal Articles

22q11.2 Microdeletion Syndrome (22q11DS) is a highly penetrant genetic mutation associated with a significantly increased risk for psychosis. Aberrant neurodevelopment may lead to inappropriate neural circuit formation and cerebral dysconnectivity in 22q11DS, which may contribute to symptom development. Here we examined: (1) differences between 22q11DS participants and typically developing controls in diffusion tensor imaging (DTI) measures within white matter tracts; (2) whether there is an altered age-related trajectory of white matter pathways in 22q11DS; and (3) relationships between DTI measures, social cognition task performance, and positive symptoms of psychosis in 22q11DS and typically developing controls. Sixty-four direction diffusion weighted imaging …

Journal Articles

It has long been recognized that generalized deficits in cognitive ability represent a core component of schizophrenia (SCZ), evident before full illness onset and independent of medication. The possibility of genetic overlap between risk for SCZ and cognitive phenotypes has been suggested by the presence of cognitive deficits in first-degree relatives of patients with SCZ; however, until recently, molecular genetic approaches to test this overlap have been lacking. Within the last few years, large-scale genome-wide association studies (GWAS) of SCZ have demonstrated that a substantial proportion of the heritability of the disorder is explained by a polygenic component consisting of …

Journal Articles

Evidence exists for late-life depression (LLD) as both a prodrome of and risk factor for Alzheimer's disease (AD). The underlying neurobiological mechanisms are poorly understood. Impaired peripheral glucose metabolism may explain the association between depression and AD given the connection between type 2 diabetes mellitus with both depression and AD. Positron emission tomography (PET) measures of cerebral glucose metabolism are sensitive to detecting changes in neural circuitry in LLD and AD. Fasting serum glucose (FSG) in non-diabetic young (YC; n=20) and elderly controls (EC; n=12) and LLD patients (n = 16) was correlated with PET scans of cerebral glucose metabolism …

Journal Articles

Schizophrenia is a highly heritable disorder. Genetic risk is conferred by a large number of alleles, including common alleles of small effect that might be detected by genome-wide association studies. Here we report a multi-stage schizophrenia genome-wide association study of up to 36,989 cases and 113,075 controls. We identify 128 independent associations spanning 108 conservatively defined loci that meet genome-wide significance, 83 of which have not been previously reported. Associations were enriched among genes expressed in brain, providing biological plausibility for the findings. Many findings have the potential to provide entirely new insights into aetiology, but associations at DRD2 and …

Affective Temperaments And Neurocognitive Functioning In Bipolar Disorder, M. Russo, K. Mahon, M. Shanahan, E. Ramjas, C. Solon, R. Braga, K. E. Burdick Jan 2014

Affective Temperaments And Neurocognitive Functioning In Bipolar Disorder, M. Russo, K. Mahon, M. Shanahan, E. Ramjas, C. Solon, R. Braga, K. E. Burdick

Journal Articles

Background: There is evidence that patients with bipolar disorder (BD) score higher on affective temperament ratings compared to healthy controls (HCs). Moreover, unaffected relatives demonstrate similar patterns as BD patients suggesting that such temperaments are related to the genetic risk for BD and may serve as endophenotypes for the disorder, It is unknown whether affective temperaments are associated with other core features of BD, such as impairments in neurocognition. This study examined the relationship between affective temperaments and neurocognition in patients with BD and in HCs. Methods: Temperaments were evaluated using the Temperament Evaluation of Memphis, Pisa, Paris, and San …

Journal Articles

22q11.2 deletion syndrome (22q11DS) is a genetic mutation associated with disorders of cortical connectivity and social dysfunction. However, little is known about the functional connectivity (FC) of the resting brain in 22q11DS and its relationship with social behavior. A seed-based analysis of resting-state functional magnetic resonance imaging data was used to investigate FC associated with the posterior cingulate cortex (PCC), in (26) youth with 22qDS and (51) demographically matched controls. Subsequently, the relationship between PCC connectivity and Social Responsiveness Scale (SRS) scores was examined in 22q11DS participants. Relative to 22q11DS participants, controls showed significantly stronger FC between the PCC and …

This study evaluates premorbid social and academic functioning in clinical high-risk individuals as predictors of transition to schizophrenia versus another psychotic disorder. Participants were 54 individuals enrolled in phase one of the North American Prodrome Longitudinal Study who over two and a half years of follow-up met criteria for schizophrenia/schizophreniform disorder (n=28) or another psychotic disorder (n=26). Social and academic functioning in childhood, early adolescence, and late adolescence was assessed at baseline using the Cannon-Spoor Premorbid Adjustment Scale. Social maladjustment in late adolescence predicted significantly higher odds of transition to schizophrenia versus another psychotic disorder independent of childhood and early …

There is inconsistent evidence for increased stress exposure among individuals at clinical high risk (CHR) for psychosis. Yet similar to patients with a diagnosed psychotic illness, the preponderance of evidence suggests that CHR individuals tend to experience stressful life events (LE) and daily hassles (DH) as more subjectively stressful than healthy individuals. The present study utilizes data from the North American Prodrome Longitudinal Study Phase 2 (NAPLS-2) to test the hypotheses that (1) CHR individuals manifest higher self-reported stress in response to both LE and DH when compared to healthy controls (HC), (2) group differences in self-reported stress increase with …

Moderator Effects Of Working Memory On The Stability Of Adhd Symptoms By Dopamine Receptor Gene Polymorphisms During Development, J. Trampush, M. M. Jacobs, Y. L. Hurd, J. H. Newcorn, J. M. Halperin

Journal Articles

We tested the hypothesis that dopamine D1 and D2 receptor gene (DRD1 and DRD2, respectively) polymorphisms and the development of working memory skills can interact to influence symptom change over 10 years in children with attention-deficit/hyperactivity disorder (ADHD). Specifically, we examined whether improvements in working memory maintenance and manipulation from childhood to early adulthood predicted the reduction of ADHD symptoms as a function of allelic variation in DRD1 and DRD2. Participants were 76 7-11-year-old children with ADHD who were genotyped and prospectively followed for almost 10 years. ADHD symptoms were rated using the Attention Problems scale on the Child Behavior …

Journal Articles

The stop-signal task, in which participants must inhibit prepotent responses, has been used to identify neural systems that vary with individual differences in inhibitory control. To explore how these differences relate to other aspects of decision making, a drift-diffusion model of simple decisions was fitted to stop-signal task data from go trials to extract measures of caution, motor execution time, and stimulus processing speed for each of 123 participants. These values were used to probe fMRI data to explore individual differences in neural activation. Faster processing of the go stimulus correlated with greater activation in the right frontal pole for …

Improving Low-Dose Blood-Brain Barrier Permeability Quantification Using Sparse High-Dose Induced Prior For Patlak Model, R. Fang, K. Karlsson, T. Chen, P. C. Sanelli

Journal Articles

Blood-brain barrier permeability (BBBP) measurements extracted from the perfusion computed tomography (PCT) using the Patlak model can be a valuable indicator to predict hemorrhagic transformation in patients with acute stroke. Unfortunately, the standard Patlak model based PCT requires excessive radiation exposure, which raised attention on radiation safety. Minimizing radiation dose is of high value in clinical practice but can degrade the image quality due to the introduced severe noise. The purpose of this work is to construct high quality BBBP maps from low-dose PCT data by using the brain structural similarity between different individuals and the relations between the high- …

White Matter Involvement In Chronic Musculoskeletal Pain, G. Lieberman, M. Shpaner, R. Watts, T. Andrews, C. G. Filippi, M. Davis, M. R. Naylor

Journal Articles

There is emerging evidence that chronic musculoskeletal pain is associated with anatomic and functional abnormalities in gray matter. However, little research has investigated the relationship between chronic musculoskeletal pain and white matter. In this study, we used whole-brain tract-based spatial statistics and region-of-interest analyses of diffusion tensor imaging data to demonstrate that patients with chronic musculoskeletal pain exhibit several abnormal metrics of white matter integrity compared with healthy controls. Chronic musculoskeletal pain was associated with lower fractional anisotropy in the splenium of the corpus callosum and the left cingulum adjacent to the hippocampus. Patients also had higher radial diffusivity in …

Imaging And Treatment Of Patients With Acute Stroke: An Evidence-Based Review, P. C. Sanelli, J. B. Sykes, A. L. Ford, J. M. Lee, K. D. Vo, D. K. Hallam

Journal Articles

Evidence-based medicine has emerged as a valuable tool to guide clinical decision-making, by summarizing the best possible evidence for both diagnostic and treatment strategies. Imaging plays a critical role in the evaluation and treatment of patients with acute ischemic stroke, especially those who are being considered for thrombolytic or endovascular therapy. Time from stroke-symptom onset to treatment is a strong predictor of long-term functional outcome after stroke. Therefore, imaging and treatment decisions must occur rapidly in this setting, while minimizing unnecessary delays in treatment. The aim of this review was to summarize the best available evidence for the diagnostic and …

Aneurysmal subarachnoid hemorrhage is associated with high morbidity and mortality, with delayed neurologic deficits from delayed cerebral ischemia contributing to a large portion of the adverse outcomes in this patient population. There is currently no consensus reference standard for establishing the diagnosis of delayed cerebral ischemia either in the research or clinical settings, ultimately limiting strategies for preventing delayed infarction and permanent neurologic deficits. There are currently both clinical and imaging-based criteria for the diagnosis of delayed neurologic deficits and vasospasm, respectively, however, neither clinical nor angiographic assessment alone has been shown to identify patients who develop adverse outcomes from …

Background Recent clinical trials have demonstrated the safety and efficacy of several non-vitamin K oral anticoagulants (NOACs) for the treatment of atrial fibrillation (AF). However, there are limited data on their use and outcomes in routine clinical practice, particularly among patients newly diagnosed as having AF and patients with AF recently transitioned to a NOAC. Methods/Design ORBIT-AF II is a multicenter, national registry of patients with AF that is enrolling up to 15,000 newly diagnosed patients with AF and/or those with AF recently transitioned to a NOAC from 300 US outpatient practices. These patients will be followed for up to …
