Journal Articles

BACKGROUND: Utility of the pipeline embolization device (PED) extending to the M1 segment as well as its clinical and flow consequences at the ICA bifurcation, has not clearly described. We describe clinical and anatomical flow modifications results at the ICA bifurcation. METHODS: In this retrospective analysis of patients treated for distal supraclinoid carotid aneurysms, a single PED was deployed from the proximal M1 segment to the distal supraclinoid carotid. Flow assessment prior to the procedure, to predict the competence of the ACA/AcomA complex, was achieved by formal DSA angiography and occasional manual cross compression. In all cases a single PED …

Semapimod Sensitizes Glioblastoma Tumors To Ionizing Radiation By Targeting Microglia, I. S. Miller, S. Didier, D. W. Murray, T. H. Turner, M. Issaivanan, R. Ruggieri, Y. Al-Abed, M. Symons

Journal Articles

Glioblastoma is the most malignant and lethal form of astrocytoma, with patients having a median survival time of approximately 15 months with current therapeutic modalities. It is therefore important to identify novel therapeutics. There is mounting evidence that microglia (specialized brain-resident macrophages) play a significant role in the development and progression of glioblastoma tumors. In this paper we show that microglia, in addition to stimulating glioblastoma cell invasion, also promote glioblastoma cell proliferation and resistance to ionizing radiation in vitro. We found that semapimod, a drug that selectively interferes with the function of macrophages and microglia, potently inhibits microglia-stimulated GL261 …


Terror Medicine As Part Of The Medical School Curriculum, L. A. Cole, K. Wagner, S. Scott, N. D. Connell, A. Cooper, C. A. Kennedy, B. Natal, S. Lamba Jan 2014

Terror Medicine As Part Of The Medical School Curriculum, L. A. Cole, K. Wagner, S. Scott, N. D. Connell, A. Cooper, C. A. Kennedy, B. Natal, S. Lamba

Journal Articles

Terror medicine, a field related to emergency and disaster medicine, focuses on medical issues ranging from preparedness to psychological manifestations specifically associated with terrorist attacks. Calls to teach aspects of the subject in American medical schools surged after the 2001 jetliner and anthrax attacks. Although the threat of terrorism persists, terror medicine is still addressed erratically if at all in most medical schools. This paper suggests a template for incorporating the subject throughout a 4-year medical curriculum. The instructional framework culminates in a short course for fourth year students, such as one recently introduced at Rutgers New Jersey Medical School, …


Sepsis: Current Dogma And New Perspectives, C. S. Deutschman, K. J. Tracey Jan 2014

Sepsis: Current Dogma And New Perspectives, C. S. Deutschman, K. J. Tracey

Journal Articles

Sepsis, a clinical syndrome occurring in patients following infection or injury, is a leading cause of morbidity andmortality worldwide. Current immunological mechanisms do not explain the basis of cellular dysfunction and organ failure, the ultimate cause of death. Here we review current dogma and argue that it is time to delineate novel immunometabolic and neurophysiological mechanisms underlying the altered cellular bioenergetics and failure of epithelial and endothelial barriers that produce organ dysfunction and death. These mechanisms might hold the key to future therapeutic strategies.


A Systematic Nomenclature For The Redox States Of High Mobility Group Box (Hmgb) Proteins, D. J. Antoine, H. E. Harris, U. Andersson, K. J. Tracey, M. E. Bianchi Jan 2014

A Systematic Nomenclature For The Redox States Of High Mobility Group Box (Hmgb) Proteins, D. J. Antoine, H. E. Harris, U. Andersson, K. J. Tracey, M. E. Bianchi

Journal Articles

High mobility group box 1 (HMGB1) is a central mediator in inflammation and immunity. Recently, it was shown that different redox states of the three cysteines of HMGB1 endow it with mutually exclusive activities, such as inducing chemotaxis or the transcription of cytokines and chemokines, via the interaction with different receptors. The different HMGB1 redox forms can be identified by mass spectrometry in body fluids of patients and may hold promise as biomarkers. We propose here a systematic nomenclature of the different redox forms of HMGB1 and related proteins, to replace the conflicting names used so far by different laboratories.

The lack of standardized reporting of the magnitude of ischemia on noninvasive imaging contributes to variability in translating the severity of ischemia across stress imaging modalities. We identified the risk of coronary artery disease (CAD) death or myocardial infarction (MI) associated with >= 10% ischemic myocardium on stress nuclear imaging as the risk threshold for stress echocardiography and cardiac magnetic resonance. A narrative review revealed that >= 10% ischemic myocardium on stress nuclear imaging was associated with a median rate of CAD death or MI of 4.9%/year (interquartile range: 3.75% to 5.3%). For stress echocardiography, >= 3 newly dysfunctional segments …

Defects in Membrane Frizzled-related Protein (MFRP) cause autosomal recessive retinitis pigmentosa (RP). MFRP codes for a retinal pigment epithelium (RPE)-specific membrane receptor of unknown function. In patient-specific induced pluripotent stem (iPS)-derived RPE cells, precise levels of MFRP, and its dicistronic partner CTRP5, are critical to the regulation of actin organization. Overexpression of CTRP5 in naive human RPE cells phenocopied behavior of MFRP-deficient patient RPE (iPS-RPE) cells. AAV8 (Y733F) vector expressing human MFRP rescued the actin disorganization phenotype and restored apical microvilli in patient-specific iPS-RPE cell lines. As a result, AAV-treated MFRP mutant iPS-RPE recovered pigmentation and transepithelial resistance. The efficacy …

Multi-Detector Coronary Ct Imaging For The Identification Of Coronary Artery Stenoses In A "Real-World" Population, A. N. Makaryus, S. Henry, L. Loewinger, J. N. Makaryus, L. Boxt

Journal Articles

BACKGROUND: Multi-detector computed tomography (CT) has emerged as a modality for the non-invasive assessment of coronary artery disease (CAD). Prior studies have selected patients for evaluation and have excluded many of the "real-world" patients commonly encountered in daily practice. We compared 64-detector-CT (64-CT) to conventional coronary angiography (CA) to investigate the accuracy of 64-CT in determining significant coronary stenoses in a "real-world" clinical population. METHODS: A total of 1,818 consecutive patients referred for 64-CT were evaluated. CT angiography was performed using the GE LightSpeed VCT (GE((R)) Healthcare). Forty-one patients in whom 64-CT results prompted CA investigation were further evaluated, and …

Implications Of Gender Difference In Coronary Calcification As Assessed By Ct Coronary Angiography, A. N. Makaryus, C. Sison, M. Kohansieh, J. N. Makaryus

Journal Articles

BACKGROUND: Arterial calcium as measured by 64-slice computed tomography coronary angiography (64-CT) is a reliable predictor of cardiovascular disease risk. Lipid-rich plaques with lower degrees of calcification may pose greater risk for adverse coronary events than more stabilized calcified plaques as a result of the increased risk of plaque rupture, migration, and subsequent acute coronary syndrome. We sought to examine coronary artery calcium scores as measured via 64-CT to assess the extent of calcification and plaque distribution in women compared to men. METHODS: A total of 138 patients referred for 64-CT were evaluated. Computerized tomographic angiography was performed using the …

Inappropriate Implantable Cardioverter-Defibrillator Shocks Attributed To Alternating-Current Leak In A Swimming Pool, J. N. Makaryus, J. Angert-Gilman, M. Yacoub, A. Patel, B. Goldner

Journal Articles

Implantable cardioverter-defibrillators (ICDs) are the standard of care for preventing sudden cardiac death in patients who are predisposed to malignant ventricular arrhythmias. Causes of inappropriate ICD shock include equipment malfunction, improper arrhythmia evaluation, misinterpretation of myopotentials, and electromagnetic interference. As the number of implanted ICDs has increased, other contributors to inappropriate therapy have become known, such as minimal electrical current leaks that mimic ventricular fibrillation. We present the case of a 63-year-old man with a biventricular ICD who received 2 inappropriate shocks, probably attributable to alternating-current leaks in a swimming pool. In addition, we discuss ICD sensitivity and offer recommendations …

Takotsubo Cardiomyopathy As A Sequela Of Elective Direct-Current Cardioversion For Atrial Fibrillation, J. S. Siegfried, S. Bhusri, N. Guttenplan, N. L. Coplan

Journal Articles

In takotsubo cardiomyopathy, the clinical appearance is that of an acute myocardial infarction in the absence of obstructive coronary artery disease, with apical ballooning of the left ventricle. The condition is usually precipitated by a stressful physical or psychological experience. The mechanism is unknown but is thought to be related to catecholamine excess. We present the case of a 67-year-old woman who experienced cardiogenic shock caused by takotsubo cardiomyopathy, immediately after undergoing elective direct-current cardioversion for atrial fibrillation. After a course complicated by left ventricular failure, cardiogenic shock, and ventricular tachycardia, she made a complete clinical and echocardiographic recovery In …
