A Rare Case Of A Primary Squamous Cell Carcinoma Of The Stomach Presenting As A Submucosal Mass, W. Von Waagner, Z. Wang, A. I. Picon Jan 2015

A Rare Case Of A Primary Squamous Cell Carcinoma Of The Stomach Presenting As A Submucosal Mass, W. Von Waagner, Z. Wang, A. I. Picon

Journal Articles

We report a case of a 70-year-old man, with a status after aortic valve replacement, who presented with melena and hypotension. On physical examination, he was hypotensive, but he responded to resuscitation. Esophagogastroduodenoscopy revealed a submucosal mass in the gastric fundus. Imaging of the chest, abdomen, and pelvis showed no evidence of local or distant metastasis. He underwent a partial diaphragmatic resection, gastrectomy, lymphadenectomy, and Roux-en-Y esophagojejunostomy. Pathology showed a gastric squamous cell carcinoma (SCC) invading the diaphragm, with negative margins of resection, and one positive perigastric lymph node. He received chemoradiation, but the patient expired 27 months after surgery.

Tbl1xr1 In Physiological And Pathological States, J. Y. Li, G. Daniels, J. Wang, X. Zhang Jan 2015

Tbl1xr1 In Physiological And Pathological States, J. Y. Li, G. Daniels, J. Wang, X. Zhang

Journal Articles

Transducin (beta)-like 1X related protein 1 (TBL1XR1/TBLR1) is an integral subunit of the NCoR (nuclear receptor corepressor) and SMRT (silencing mediator of retinoic acid and thyroid hormone receptors) repressor complexes. It is an evolutionally conserved protein that shares high similarity across all species. TBL1XR1 is essential for transcriptional repression mediated by unliganded nuclear receptors (NRs) and othe regulated transcription factors (TFs). However, it can also act as a transcription activator through the recruitment of the ubiquitin-conjugating/19S proteasome complex that mediates the exchange of corepressors for coactivators. TBL1XR1 is required for the activation of multiple intracellular signaling pathways. TBL1XR1 germline mutations …

Utility Of Telepathology As A Consultation Tool Between An Off-Site Surgical Pathology Suite And Affiliated Hospitals In The Frozen Section Diagnosis Of Lung Neoplasms, T. Vitkovski, T. Bhuiya, M. Esposito Jan 2015

Utility Of Telepathology As A Consultation Tool Between An Off-Site Surgical Pathology Suite And Affiliated Hospitals In The Frozen Section Diagnosis Of Lung Neoplasms, T. Vitkovski, T. Bhuiya, M. Esposito

Journal Articles

BACKGROUND: Increasingly, as in our institution, operating rooms are located in hospitals and the pathology suite is located at a distant location because of off-site consolidation of pathology services. Telepathology is a technology which bridges the gap between pathologists and offers a means to obtain a consultation remotely. We aimed to evaluate the utility of telepathology as a means to assist the pathologist at the time of intraoperative consultation of lung nodules when a subspecialty pathologist is not available to directly review the slide. METHODS: Cases of lung nodules suspicious for a neoplasm were included. Frozen sections were prepared in …

Journal Articles

Little is known regarding the neuropsychological significance of resting state functional magnetic resonance imaging (rs-fMRI) activity early in the course of psychosis. Moreover, no studies have used different approaches for analysis of rs-fMRI activity and examined gray matter thickness in the same cohort. In this study, 41 patients experiencing a first-episode of psychosis (including N = 17 who were antipsychotic drug-naive at the time of scanning) and 41 individually age-and sex-matched healthy volunteers completed rs-fMRI and structural MRI exams and neuropsychological assessments. We computed correlation matrices for 266 regions-of-interest across the brain to assess global connectivity. In addition, independent component …

Journal Articles

IMPORTANCE: Severe neuropsychiatric conditions, such as schizophrenia, affect distributed neural computations. One candidate system profoundly altered in chronic schizophrenia involves the thalamocortical networks. It is widely acknowledged that schizophrenia is a neurodevelopmental disorder that likely affects the brain before onset of clinical symptoms. However, no investigation has tested whether thalamocortical connectivity is altered in individuals at risk for psychosis or whether this pattern is more severe in individuals who later develop full-blown illness. OBJECTIVES: To determine whether baseline thalamocortical connectivity differs between individuals at clinical high risk for psychosis and healthy controls, whether this pattern is more severe in those …

Journal Articles

In studies describing the long-term follow-up up of youth at clinical high risk (CHR) of psychosis, little attention has been given to details of specific prodromal symptoms. In this paper, we describe the prodromal symptoms of 764 CHR participants recruited in the multi-site North American Prodrome Longitudinal Study (NAPLS). Symptoms were rated on the Scale of Prodromal Symptoms (SOPS) at baseline and 6-, 12-, 18-, and 24-month follow-ups. Clinical outcome at the 2-year assessment was categorized as psychotic, prodromal progression, symptomatic or in remission. Most of the CHR sample (92%) met criteria for the attenuated positive symptoms syndrome (APSS). Significant …

Strategies For Health Research: Lessons From 3 Mobile Intervention Studies, D. Ben-Zeev, S. M. Schueller, M. Begale, J. Duffecy, J. M. Kane, D. C. Mohr

Journal Articles

The capacity of Mobile Health (mHealth) technologies to propel healthcare forward is directly linked to the quality of mobile interventions developed through careful mHealth research. mHealth research entails several unique characteristics, including collaboration with technologists at all phases of a project, reliance on regional telecommunication infrastructure and commercial mobile service providers, and deployment and evaluation of interventions "in the wild", with participants using mobile tools in uncontrolled environments. In the current paper, we summarize the lessons our multi-institutional/multi-disciplinary team has learned conducting a range of mHealth projects using mobile phones with diverse clinical populations. First, we describe three ongoing projects …

PURPOSE: Carrier screening programs that identify the presence of known mutations have been effective for reducing the incidence of autosomal recessive conditions in the Ashkenazi Jewish (AJ) population and other populations. Yet, these programs have not realized their full potential. Furthermore, many known autosomal recessive and dominant conditions are not screened for and the molecular basis of other conditions for which screening might be offered is unknown. METHODS: Through literature review and annotation of full sequenced genomes from healthy individuals, we expanded the list of mutations. Mutations were identified in a sample of 128 fully sequenced AJ genomes that were …

Role Of Social Media And The Internet In Pathways To Care For Adolescents And Young Adults With Psychotic Disorders And Non-Psychotic Mood Disorders, M. L. Birnbaum, A. F. Rizvi, Christoph Correll, J. M. Kane Jan 2015

Role Of Social Media And The Internet In Pathways To Care For Adolescents And Young Adults With Psychotic Disorders And Non-Psychotic Mood Disorders, M. L. Birnbaum, A. F. Rizvi, Christoph Correll, J. M. Kane

Journal Articles

AIMS: Although psychosis often occurs during adolescence, there has been little research on how the ubiquitously used Internet and social media could impact pathways to care. We examined how youth with psychotic spectrum disorders (PSD) versus non-psychotic mood disorders (NPMD) use online resources in the early illness stages. METHODS: Social media use and pathways to care data were collected using a semi-structured interview from 80 youth (PSD = 40 and NPMD = 40) aged 12-21 years within 2 years of symptom onset. RESULTS: A total of 97.5% of participants (mean age = 18.3 years) regularly used social media, spending approximately …

Perfectionism Related To Self-Reported Insomnia Severity, But Not When Controlled For Stress And Emotion Regulation, S. Brand, R. Kirov, N. Kalak, M. Gerber, U. Puhse, S. Lemola, Christoph Correll, S. Cortese, T. Meyer, E. Holsboer-Trachsler Jan 2015

Perfectionism Related To Self-Reported Insomnia Severity, But Not When Controlled For Stress And Emotion Regulation, S. Brand, R. Kirov, N. Kalak, M. Gerber, U. Puhse, S. Lemola, Christoph Correll, S. Cortese, T. Meyer, E. Holsboer-Trachsler

Journal Articles

Background: Perfectionism is understood as a set of personality traits such as unrealistically high and rigid standards for performance, fear of failure, and excessive self-criticism. Previous studies showed a direct association between increased perfectionism and poor sleep, though without taking into account possible mediating factors. Here, we tested the hypothesis that perfectionism was directly associated with poor sleep, and that this association collapsed, if mediating factors such as stress and poor emotion regulation were taken into account. Methods: Three hundred and forty six young adult students (M=23.87 years) completed questionnaires relating to perfectionism traits, sleep, and psychological functioning such as …

Long-Acting Injectable Versus Daily Oral Antipsychotic Treatment Trials In Schizophrenia: Pragmatic Versus Explanatory Study Designs, C. A. Bossie, L. D. Alphs, Christoph Correll Jan 2015

Long-Acting Injectable Versus Daily Oral Antipsychotic Treatment Trials In Schizophrenia: Pragmatic Versus Explanatory Study Designs, C. A. Bossie, L. D. Alphs, Christoph Correll

Journal Articles

Trial design characteristics related to the explanatory:pragmatic spectrum may contribute toward the inconsistent results reported in studies comparing long-acting injectable (LAI) versus daily oral antipsychotic (AP) treatments in schizophrenia. A novel approach examined the hypothesis that a more pragmatic design is important to show the advantages of LAI versus oral APs. A literature search identified comparative studies assessing the clinical efficacy/effectiveness of LAI versus oral APs in more than 100 schizophrenia patients, with 6-month or more duration/follow-up, and published between January 1993 and December 2013 (n=11). Each study's design was rated using the six-domain ASPECT-R (A Study Pragmatic:Explanatory Characterization Tool-Rating). …

Among people with psychosis, those with a history of cannabis use show better cognitive performance than those who are cannabis naive. It is unknown whether this pattern is present in youth at clinical high risk (CHR) of psychosis. We evaluated relationships between IQ and cannabis use while controlling for use of other substances known to impact cognition in 678 CHR and 263 healthy control (HC) participants. IQ was estimated using the Vocabulary and Block Design subtests of the Wechsler Abbreviated Scale of Intelligence. Drug and alcohol use severity and frequency were assessed with the Alcohol and Drug Use Scale, and …

Interpersonal Functioning In Obsessive-Compulsive Personality Disorder, N. M. Cain, E. B. Ansell, H. B. Simpson, A. Pinto Jan 2015

Interpersonal Functioning In Obsessive-Compulsive Personality Disorder, N. M. Cain, E. B. Ansell, H. B. Simpson, A. Pinto

Journal Articles

The core symptoms of obsessive-compulsive personality disorder (OCPD) often lead to interpersonal difficulties. However, little research has explored interpersonal functioning in OCPD. This study examined interpersonal problems, interpersonal sensitivities, empathy, and systemizing, the drive to analyze and derive underlying rules for systems, in a sample of 25 OCPD individuals, 25 individuals with comorbid OCPD and obsessive-compulsive disorder (OCD), and 25 healthy controls. We found that OCPD individuals reported hostile-dominant interpersonal problems and sensitivities with warm-dominant behavior by others, whereas OCPD+OCD individuals reported submissive interpersonal problems and sensitivities with warm-submissive behavior by others. Individuals with OCPD, with and without OCD, reported …

The Impact Of Psychosis On The Course Of Cognition: A Prospective, Nested Case-Control Study In Individuals At Clinical High-Risk For Psychosis, R. Carrion, D. Mclaughlin, A. M. Auther, R. Olsen, Christoph Correll, B. A. Cornblatt

Journal Articles

BACKGROUND: Although cognitive deficits in patients with schizophrenia are rooted early in development, the impact of psychosis on the course of cognitive functioning remains unclear. In this study a nested case-control design was used to examine the relationship between emerging psychosis and the course of cognition in individuals ascertained as clinical high-risk (CHR) who developed psychosis during the study (CHR + T). METHOD: Fifteen CHR + T subjects were administered a neurocognitive battery at baseline and post-psychosis onset (8.04 months, s.d. = 10.26). CHR + T subjects were matched on a case-by-case basis on age, gender, and time to retest …

Journal Articles

Both polygenicity (many small genetic effects) and confounding biases, such as cryptic relatedness and population stratification, can yield an inflated distribution of test statistics in genome-wide association studies (GWAS). However, current methods cannot distinguish between inflation from a true polygenic signal and bias. We have developed an approach, LD Score regression, that quantifies the contribution of each by examining the relationship between test statistics and linkage disequilibrium (LD). The LD Score regression intercept can be used to estimate a more powerful and accurate correction factor than genomic control. We find strong evidence that polygenicity accounts for the majority of the …

Contributions Of Early Cortical Processing And Reading Ability To Functional Status In Individuals At Clinical High Risk For Psychosis, R. Carrion, B. A. Cornblatt, D. Mclaughlin, J. Chang, A. M. Auther, R. H. Olsen, D. C. Javitt Jan 2015

Contributions Of Early Cortical Processing And Reading Ability To Functional Status In Individuals At Clinical High Risk For Psychosis, R. Carrion, B. A. Cornblatt, D. Mclaughlin, J. Chang, A. M. Auther, R. H. Olsen, D. C. Javitt

Journal Articles

Background: There is a growing recognition that individuals at clinical high risk need intervention for functional impairments, along with emerging psychosis, as the majority of clinical high risk (CHR) individuals show persistent deficits in social and role functioning regardless of transition to psychosis. Recent studies have demonstrated reduced reading ability as a potential cause of functional disability in schizophrenia, related to underlying deficits in generation of mismatch negativity (MMN). The present study extends these findings to subjects at CHR. Methods: The sample consisted of 34 CHR individuals and 33 healthy comparison subjects (CNTLs) from the Recognition and Prevention (RAP) Program …

Postnatal Neurodevelopmental Expression And Glutamate-Dependent Regulation Of The Znf804a Rodent Homologue, E. H. Chang, A. Kirtley, T. S. Chandon, P. Borger, S. Husain-Krautter, V. Vingtdeux, A. Malhotra Jan 2015

Postnatal Neurodevelopmental Expression And Glutamate-Dependent Regulation Of The Znf804a Rodent Homologue, E. H. Chang, A. Kirtley, T. S. Chandon, P. Borger, S. Husain-Krautter, V. Vingtdeux, A. Malhotra

Journal Articles

The zinc finger protein ZNF804A rs1344706 variant is a replicated genome-wide significant risk variant for schizophrenia and bipolar disorder. While its association with altered brain structure and cognition in patients and healthy risk allele carriers is well documented, the characteristics and function of the gene in the brain remains poorly understood. Here, we used in situ hybridization to determine mRNA expression levels of the ZNF804A rodent homologue, Zfp804a, across multiple postnatal neurodevelopmental time points in the rat brain. We found changes in Zfp804a expression in the rat hippocampus, frontal cortex, and thalamus across postnatal neurodevelopment. Zfp804a mRNA peaked at postnatal …

Journal Articles

A recent prospective longitudinal neuroimaging study of 274 prodromal risk syndrome subjects revealed that those who later developed full-blown psychotic symptoms exhibited accelerated gray matter loss and third ventricle expansion around the time of onset of psychosis. Previous studies also indicate that higher levels of unusual thought content during prodromal states are a significant predictor of psychosis in clinically high-risk youth (CHR). However, the relationship between clinical symptoms and changes in neuroanatomical structure has not been previously examined in the North American Prodrome Longitudinal Study (NAPLS) sample at the atlas level. In this report, we investigated whether symptom severity as …

Abnormal Movements In First-Episode, Nonaffective Psychosis: Dyskinesias, Stereotypies, And Catatonic-Like Signs, M. T. Compton, F. Fantes, C. R. Wan, S. Johnson, E. F. Walker

Journal Articles

Motor abnormalities represent a neurobehavioral domain of signs intrinsic to schizophrenia-spectrum disorders, though they are commonly attributed to medication side effects and remain understudied. Individuals with first-episode psychosis represent an ideal group to study innate movement disorders due to minimal prior antipsychotic exposure. We measured dyskinesias, stereotypies, and catatonic-like signs and examined their associations with: (1) age at onset of psychotic symptoms and duration of untreated psychosis; (2) positive, negative, and disorganized symptoms; (3) neurocognition; and (4) neurological soft signs. Among 47 predominantly African American first-episode psychosis patients in a public-sector hospital, the presence and severity of dyskinesias, stereotypies, and …

OBJECTIVES: Early-course psychotic disorders have been extensively studied in terms of phenomenology, but little is known about the influence of personality traits on clinical features of first-episode psychosis. The aim of this study was to explore how the "big five" personality domains (neuroticism, extraversion, openness, agreeableness, and conscientiousness) are associated with treatment delay (duration of untreated psychosis, DUP), functioning, and positive and negative symptom severity. METHODS: Data for these analyses were obtained from 104 participants enrolled from psychiatric inpatient units in Atlanta, Georgia, between August 2008 and March 2011. The NEO Five-Factor Inventory (NEO-FFI) was used to assess personality domains, …

Psychosis Prevention: A Modified Clinical High Risk Perspective From The Recognition And Prevention (Rap) Program, B. A. Cornblatt, R. Carrion, A. Auther, D. Mclaughlin, R. H. Olsen, M. John, C. U. Correll

Journal Articles

OBJECTIVE: Early intervention and prevention of psychosis remain a major challenge. Prediction would be greatly advanced with improved ability to identify individuals at true risk, which, at present, is moderate at best. The authors tested a modified strategy to improve prediction by selecting a more homogeneous high-risk sample (attenuated positive symptom criteria only, age range of mid-teens to early 20s) than is currently standard, combined with a systematic selection of neurodevelopmental deficits. METHOD: A sample of 101 treatment-seeking adolescents (mean age, 15.9 years) at clinical high risk for psychosis were followed clinically for up to 5 years (mean follow-up time, …

Responses To Tobacco Smoking-Related Health Messages In Young People With Recent-Onset Schizophrenia, D. J. Coletti, M. Brunette, M. John, J. M. Kane, A. Malhotra, D. G. Robinson

Journal Articles

Virtually no research has examined the responses of youth with recent-onset psychosis (ROP) to smoking-related health warnings. We examined predictors of response and tested hypotheses that participants with ROP would (a) assess warnings as less effective than a healthy comparison (HC) group, and (b) assess video warnings as more effective than pictures. ROP participants (n = 69) hadtreatment; the HC group (n = 79) had no major mental illness. Participants viewed 10 pictorial warnings, 8 videos depicting similar messages, and were interviewed regarding tobacco use, health literacy, and smoking knowledge. We assessed response at baseline and at 4-week follow-up. ROP …
