Diagnosing Crohn's Disease: An Economic Analysis Comparing Wireless Capsule Endoscopy With Traditional Diagnostic Procedures, Neil I. Goldfarb, Laura T. Pizzi, Joseph P. Fuhr Jr., Christopher Salvador, Vanja Sikirica, Asher Kornbluth, Blair Lewis

College of Population Health Faculty Papers

The purpose of this study was to review economic considerations related to establishing a diagnosis of Crohn's disease, and to compare the costs of a diagnostic algorithm incorporating wireless capsule endoscopy (WCE) with the current algorithm for diagnosing Crohn's disease suspected in the small bowel. Published literature, clinical trial data on WCE in comparison to other diagnostic tools, and input from clinical experts were used as data sources for (1) identifying contributors to the costs of diagnosing Crohn's disease; (2) exploring where WCE should be placed within the diagnostic algorithm for Crohn's; and (3) constructing decision tree models with sensitivity …

Characterization Of The Chicken Inward Rectifier K+ Channel Irk1/Kir2.1 Gene., Hideki Mutai, Lawrence C Kenyon, Emily Locke, Nami Kikuchi, John Carl Oberholtzer

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: Inward rectifier potassium channels (IRK) contribute to the normal function of skeletal and cardiac muscle cells. The chick inward rectifier K+ channel cIRK1/Kir2.1 is expressed in skeletal muscle, heart, brain, but not in liver; a distribution similar but not identical to that of mouse Kir2.1. We set out to explore regulatory domains of the cIRK1 promoter that enhance or inhibit expression of the gene in different cell types. RESULTS: We cloned and characterized the 5'-flanking region of cIRK1. cIRK1 contains two exons with splice sites in the 5'-untranslated region, a structure similar to mouse and human orthologs. cIRK1 has …

Control Of Mitochondrial Motility And Distribution By The Calcium Signal: A Homeostatic Circuit., Muqing Yi, David Weaver, György Hajnóczky

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Mitochondria are dynamic organelles in cells. The control of mitochondrial motility by signaling mechanisms and the significance of rapid changes in motility remains elusive. In cardiac myoblasts, mitochondria were observed close to the microtubular array and displayed both short- and long-range movements along microtubules. By clamping cytoplasmic [Ca2+] ([Ca2+]c) at various levels, mitochondrial motility was found to be regulated by Ca2+ in the physiological range. Maximal movement was obtained at resting [Ca2+]c with complete arrest at 1-2 microM. Movement was fully recovered by returning to resting [Ca2+]c, and inhibition could be repeated with no apparent desensitization. The inositol 1,4,5-trisphosphate- or …

Complementary Medicine In Chronic Cancer Care, Daniel A. Monti, Jingduan Yang

Marcus Institute of Integrative Health Faculty Papers

Although advancements in cancer care have led to increased cure rates and survival times, those coping with the long-term sequelae of a cancer diagnosis often report high levels of distress, poor health-related quality of life, and unmet psychosocial needs. The shortcomings of the conventional biomedical system at sufficiently addressing these chronic illness issues are a primary reason that many patients turn to complementary and alternative medicine (CAM). Although patients usually use such treatments in addition to conventional care, they often do not discuss doing so with their conventional physicians, who are perceived as being unreceptive to the topic. Physicians may …

Access To Quality Care: Links Between Evidence, Nursing Language, And Informatics, Beth Ann Swan Phd, Crnp, Norma M. Lang Phd, Rn, Faan, Frcn, Anne M. Mcginley Phd, Crnp

College of Nursing Faculty Papers & Presentations

Despite evidence on nursing’s contribution to the quality of care, much of what nurses “do” remains essentially invisible.

It is vital to recognize the need for a paradigm shift in nursing that utilizes new informatics tools required for optimum use of evidence related to the delivery of quality nursing care.

Embedding nursing language within informatics structures is essential to make the work of nurses visible, and articulate evidence about the quality and value of nursing in the care of patients, groups, and populations.

Dynamic Mechanical (Brush) Allodynia In Cluster Headache, Avi Ashkenazi, William B. Young

Department of Neurology Faculty Papers

Cutaneous allodynia is the perception of pain when a non-noxious stimulus is applied to normal skin. It has been described in patients with migraine. Cutaneous allodynia is caused by sensitization of central nervous system neurons that receive convergent sensory input from both skin and intracranial structures. This phenomenon has not been previously described in patients with cluster headache. Although migraine and cluster headache (CH) may share some clinical features, the pathogenesis of these two primary headaches is different. The aim of this study was to examine the occurrence of dynamic mechanical (brush) allodynia (BA) in patients with CH.

Periodic Autonomic Dysfunction Without Pain In A Patient With Cluster Headache, Avi Ashkenazi, Stephen Silberstein

Department of Neurology Faculty Papers

Cluster headache (CH) is characterized by episodes of severe unilateral headache accompanied by symptoms of cranial parasympathetic hyperactivity and sympathetic dysfunction that occur in cluster periods. Positron emission tomography (PET) studies have demonstrated evidence of a central generator of CH attacks located in the posterior-inferior hypothalamus. It has been suggested that the autonomic symptoms in CH result from reflex activation of the superior salivatory nucleus secondary to activation of the trigeminal nucleus caudalis (TNC). However, several cases of CH-like symptoms with no head pain have been documented.

We describe a patient who had suffered from typical episodic CH for two …

Inhibition Of Glucocorticoid-Induced Apoptosis By Targeting Splice Variants Of Bim Mrna With Small Interfering Rna And Short Hairpin Rna., Marc T. Abrams, Noreen M. Robertson, Kyonggeun Yoon, Eric Wickstrom

Department of Biochemistry and Molecular Biology Faculty Papers

Glucocorticoids (GCs) induce apoptosis in lymphocytes and are effective agents for the treatment of leukemia. The activated glucocorticoid receptor (GR) initiates a transcriptional program leading to caspase activation and cell death, but the critical signaling intermediates in GC-induced apoptosis remain largely undefined. We have observed that GC induction of the three major protein products of the Bcl-2 relative Bim (BimEL, BimS and BimL) correlates with GC sensitivity in a panel of human pre-B acute lymphoblastic leukemia (ALL) cell lines. To test the hypothesis that Bim facilitates GC-induced apoptosis, we reduced BIM mRNA levels and Bim protein levels by RNA interference …

Relationship Of Serum Prolactin With Severity Of Drug Use And Treatment Outcome In Cocaine Dependence., Ashwin A. Patkar, Paolo Mannelli, Kenneth M. Certa, Kathleen Peindl, Heather Murray, Michael J. Vergare, Wade H. Berrettini

Department of Psychiatry and Human Behavior Faculty Papers

RATIONALE: Alteration in serum prolactin (PRL) levels may reflect changes in central dopamine activity, which modulates the behavioral effects of cocaine. Therefore, serum PRL may have a potential role as a biological marker of drug severity and treatment outcome in cocaine dependence.

OBJECTIVE: We investigated whether serum PRL levels differed between cocaine-dependent (CD) subjects and controls, and whether PRL levels were associated with severity of drug use and treatment outcome in CD subjects.

METHODS: Basal PRL concentrations were assayed in 141 African-American (AA) CD patients attending an outpatient treatment program and 60 AA controls. Severity of drug use was assessed …

Occipital Nerve Block Rapidly Eliminates Allodynia Far From The Site Of Headache: A Case Report, William B. Young, Valentin Mateos, Avi Ashkenazi

Department of Neurology Faculty Papers

Seventy to 80% of persons with migraine develop allodynia during the course of a severe attack. During a migraine attack, allodynia spreads topographically to extratrigeminal territory. Dynamic mechanical allodynia, otherwise known as brush allodynia (BA), is a subtype of allodynia that is easily tested. Ashkenazi & Young recently reported on the immediate benefits of greater occipital nerve (GON) block on brush allodynia and pain in migraine and in cluster headache. In these studies, testing was performed at fixed sites in the trigeminal and cervical distributions. Allodynia in thoracic dermatomes was not studied.

Heme Oxygenase-2 Gene Deletion Attenuates Oxidative Stress In Neurons Exposed To Extracellular Hemin., Raymond F Regan, Jing Chen, Luna Benvenisti-Zarom

Department of Emergency Medicine Faculty Papers

BACKGROUND: Hemin, the oxidized form of heme, accumulates in intracranial hematomas and is a potent oxidant. Growing evidence suggests that it contributes to delayed injury to surrounding tissue, and that this process is affected by the heme oxygenase enzymes. In a prior study, heme oxygenase-2 gene deletion increased the vulnerability of cultured cortical astrocytes to hemin. The present study tested the effect of HO-2 gene deletion on protein oxidation, reactive oxygen species formation, and cell viability after mixed cortical neuron/astrocyte cultures were incubated with neurotoxic concentrations of hemin. RESULTS: Continuous exposure of wild-type cultures to 1-10 microM hemin for 14 …

Headache Management For The Pain Specialist, Avi Ashkenazi, Stephen Silberstein

Department of Neurology Faculty Papers

Headache is a common symptom caused by a wide variety of diseases. Primary headaches include migraine, cluster headache, tension-type headache and other less common diseases. It is important to differentiate these headaches from secondary headaches caused by vascular, neoplastic, infectious, metabolic and toxic disorders. Most primary headaches have a genetic basis, with environmental factors acting as triggers. Recent advances in basic research resulted in the development of more specific and effective therapies. Medication overuse headache is a very common cause of chronic daily headache. Detoxification from the offending drug is essential for headache improvement. Cervicogenic headache is common and needs …

Collecting Duct Carcinoma Of The Kidney: An Immunohistochemical Study Of 11 Cases., Andrea Vecchione, Tommaso Prayer Galetti, Marina Gardiman, Hideshi Ishii, Enrico Giarnieri, Francesco Pagano, Leonard G Gomella, Carlo M Croce, Raffaele Baffa

Department of Urology Faculty Papers

BACKGROUND: Collecting duct carcinoma (CDC) is a rare but very aggressive variant of kidney carcinoma that arises from the epithelium of Bellini's ducts, in the distal portion of the nephron. In order to gain an insight into the biology of this tumor we evaluated the expression of five genes involved in the development of renal cancer (FEZ1/LZTS1, FHIT, TP53, P27kip1, and BCL2). METHODS: We studied eleven patients who underwent radical nephrectomy for primary CDC. All patients had an adequate clinical follow-up and none of them received any systemic therapy before surgery. The expression of the five markers for tumor initiation …

Durable Cytotoxic Immune Responses Against Gp120 Elicited By Recombinant Sv40 Vectors Encoding Hiv-1 Gp120 +/- Il-15., Hayley J Mckee, Patricia Y T'Sao, Maria Vera, Puri Fortes, David S Strayer

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: A vaccine that elicits durable, powerful anti-HIV immunity remains an elusive goal. In these studies we tested whether multiple treatments with viral vector-delivered HIV envelope antigen (gp120), with and without IL-15, could help to approach that goal. For this purpose, we used recombinant Tag-deleted SV40-derived vectors (rSV40s), since they do not elicit neutralizing antibody responses, and so can be given multiply without loss of transduction efficiency. METHODS: SV(gp120) carried the coding sequences for HIV-1NL4-3 Env, and SV(mIL-15) carried the cDNA for mouse IL-15. Singly, and in combination, these two vectors were given monthly to BALB/cJ mice. Cytotoxic immunity and …

Similar Promotion Of Abeta1-42 Fibrillogenesis By Native Apolipoprotein E Epsilon3 And Epsilon4 Isoforms., David Sweeney, Ralph Martins, Harry Levine, Jonathan D Smith, Sam Gandy

Farber Institute for Neuroscience Faculty Papers

The apolipoprotein E epsilon4 allele contributes to the genetic susceptibility underlying a large proportion (~40-60%) of typical, sporadic Alzheimer disease. Apolipoprotein E deficient mice made transgenic for human apolipoprotein E epsilon4 accumulate excess cerebral amyloid when compared to similarly prepared mice expressing human apolipoprotein E epsilon3. Therefore, it is important to search for relevant interactions(s) between apolipoprotein E epsilon4 and Abeta in order to clarify the biological role for apolipoprotein E epsilon4 in Alzheimer disease. Using a thioflavine T (ThT)-based assay, we have investigated the effects of native human apolipoprotein E isoforms on the kinetics of Abeta fibrillogenesis. No obvious …

Esophageal Muscle Physiology And Morphogenesis Require Assembly Of A Collagen Xix-Rich Basement Membrane Zone., Hideaki Sumiyoshi, Niv Mor, Sui Y Lee, Stephen Doty, Scott Henderson, Shizuko Tanaka, Hidekatsu Yoshioka, Satish Rattan, Francesco Ramirez

Department of Medicine Faculty Papers

Collagen XIX is an extremely rare extracellular matrix component that localizes to basement membrane zones and is transiently expressed by differentiating muscle cells. Characterization of mice harboring null and structural mutations of the collagen XIX (Col19a1) gene has revealed the critical contribution of this matrix protein to muscle physiology and differentiation. The phenotype includes smooth muscle motor dysfunction and hypertensive sphincter resulting from impaired swallowing-induced, nitric oxide-dependent relaxation of the sphincteric muscle. Muscle dysfunction was correlated with a disorganized matrix and a normal complement of enteric neurons and interstitial cells of Cajal. Mice without collagen XIX exhibit an additional defect, …

Hsp27 Anti-Sense Oligonucleotides Sensitize The Microtubular Cytoskeleton Of Chinese Hamster Ovary Cells Grown At Low Ph To 42 Degrees C-Induced Reorganization, Michael T. Hargis, C. W. Storck, Eric Wickstrom, Leonid A. Yakubov, Dennis B. Leeper, Ronald A. Coss

Department of Biochemistry and Molecular Biology Faculty Papers

Chinese hamster ovary (CHO) cells maintained in vitro at pH 6.7 were used to model cells in the acidic environment of tumours. CHO cells grown at pH 6.7 develop thermotolerance during 42 degrees C heating at pH 6.7 and their cytoskeletal systems are resistant to 42 degrees C-induced perinuclear collapse. Hsp27 levels are elevated in cells grown at pH 6.7 and are further induced during 42 degrees C heating, while Hsp70 levels remain low or undetectable, suggesting that Hsp27 is responsible for some of the novel characteristics of these cells. An anti-sense oligonucleotide strategy was used to test the importance …

Biochemical Enrichment And Biophysical Characterization Of A Taste Receptor For L-Arginine From The Catfish, Ictalurus Puntatus., William Grosvenor, Yuri Kaulin, Andrew I Spielman, Douglas L Bayley, D Lynn Kalinoski, John H Teeter, Joseph G Brand

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

BACKGROUND: The channel catfish, Ictalurus punctatus, is invested with a high density of cutaneous taste receptors, particularly on the barbel appendages. Many of these receptors are sensitive to selected amino acids, one of these being a receptor for L-arginine (L-Arg). Previous neurophysiological and biophysical studies suggested that this taste receptor is coupled directly to a cation channel and behaves as a ligand-gated ion channel receptor (LGICR). Earlier studies demonstrated that two lectins, Ricinus communis agglutinin I (RCA-I) and Phaseolus vulgaris Erythroagglutinin (PHA-E), inhibited the binding of L-Arg to its presumed receptor sites, and that PHA-E inhibited the L-Arg-stimulated ion conductance …

Gitr Activation Induces An Opposite Effect On Alloreactive Cd4(+) And Cd8(+) T Cells In Graft-Versus-Host Disease., Stephanie J Muriglan, Teresa Ramirez-Montagut, Onder Alpdogan, Thomas W Van Huystee, Jeffrey M Eng, Vanessa M Hubbard, Adam A Kochman, Kartono H Tjoe, Carlo Riccardi, Pier Paolo Pandolfi, Shimon Sakaguchi, Alan N Houghton, Marcel R M Van Den Brink

Department of Medical Oncology Faculty Papers

Glucocorticoid-induced tumor necrosis factor receptor family-related gene (GITR) is a member of the tumor necrosis factor receptor (TNFR) family that is expressed at low levels on unstimulated T cells, B cells, and macrophages. Upon activation, CD4(+) and CD8(+) T cells up-regulate GITR expression, whereas immunoregulatory T cells constitutively express high levels of GITR. Here, we show that GITR may regulate alloreactive responses during graft-versus-host disease (GVHD) after allogeneic bone marrow transplantation (BMT). Using a BMT model with major histocompatibility complex class I and class II disparity, we demonstrate that GITR stimulation in vitro and in vivo enhances alloreactive CD8(+)CD25(-) T …

Predictors Of Paralysis In The Rheumatoid Cervical Spine In Patients Undergoing Total Joint Arthroplasty., Jonathan N Grauer, Edwin M Tingstad, Nahshon Rand, Michael J Christie, Alan Hilibrand

Rothman Institute Faculty Papers

BACKGROUND: Rheumatoid arthritis is sometimes associated with radiographic evidence of instability of the cervical spine, most commonly an abnormal subluxation between vertebrae. When this instability compromises the space that is available for the spinal cord, it may be predictive of paralysis. However, the prevalence of radiographic signs of instability that are predictive of paralysis among patients with nonspinal orthopaedic manifestations of rheumatoid arthritis is unknown.

METHODS: Radiographs of the cervical spine of patients with rheumatoid arthritis who had undergone total joint arthroplasty over a five-year period were retrospectively reviewed. The radiographs were evaluated for predictors of paralysis (a posterior atlantodental …
