Rosuvastatin Therapy Does Not Affect Serum Mmp-13 Or Timp-1 Levels In Hypercholesterolemic Patients, Cihan Cevik, Kenneth Nugent, Gary Meyerrose, Mohammad Otahbachi, Cemil Izgi, Mark Lyte, R David Fish

The Texas Heart Institute Journal

Matrix metalloproteinases degrade the collagen content of atherosclerotic plaque and reduce plaque stability. In tissue sections of atherosclerotic plaque, the expression of matrix metalloproteinases is increased. 3-Hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) decrease the tissue expression of matrix metalloproteinases-1, -2, -3, and -9 in atheromatous plaque by attenuating the inflammatory process that leads to increased expression. However, it is not known whether statins decrease levels of matrix metalloproteinase-13—an enzyme crucial to the initiation of collagen degradation—as part of their plaque-stabilizing effect.

We prospectively examined the effect of statin therapy on serum levels of matrix metalloproteinase-13, tissue inhibitor of metalloproteinase-1, and …

Surgical Management Of Double-Chambered Right Ventricle In Adults, Ahmad K Darwazah, Mohammed Eida, Vivian Bader, Mohammed Khalil

The Texas Heart Institute Journal

Double-chambered right ventricle is a congenital anomaly in which the right ventricle is divided into 2 portions by anomalous muscle bundles. These cases often present in children, but rarely in adults.

We discuss 2 cases of double-chambered right ventricle, in patients aged 42 and 35 years. When cases remain asymptomatic until adulthood, they can present with unusual symptoms that lead to incorrect diagnosis. Our cases represent 2 very different manifestations of double-chambered right ventricle, which differ in presentation, in the site of abnormal obstructive muscle bundles, and in the presence of associated lesions. Both of our patients underwent successful surgical …

High-Risk Diabetic Patients With Unprotected Left Main Coronary Artery Disease: Characteristics And Medium-Term Outcomes Of Percutaneous Revascularization With Drug-Eluting Stents, Jose F Díaz Fernández, Carlos Sánchez González, Manuel Jiménez Navarro, Juan C Fernández Guerrero, Antonio Gómez Menchero, Juan H Alonso Briales, Rosa María Cardenal Piris, Juan Herrador, Manuel Guzmán Herrera, Jose M Hernández García

The Texas Heart Institute Journal

Percutaneous coronary intervention with drug-eluting stents is an alternative for patients with high-risk unprotected left main coronary artery disease; those with diabetes mellitus are at even higher risk. Recent advances in percutaneous coronary intervention could lead to better results. The aim of this study was to evaluate medium-term results in a real-world sample of high-risk diabetic patients undergoing percutaneous coronary intervention with drug-eluting stents for unprotected left main coronary artery disease.

From 3 tertiary hospitals, we retrospectively identified 334 high-risk patients, of whom 141 (42%) were diabetic and 193 (58%) were nondiabetic. The diabetes mellitus group showed a higher prevalence …

Closure Of A Para-Valvular Aortic Leak With The Use Of 2 Amplatzer Devices And Real-Time 2− And 3-Dimensional Transesophageal Echocardiography, Kurt S Hoffmayer, Christian Zellner, Damon M Kwan, Suma Konety, Elyse Foster, Phillip Moore, Yerem Yeghiazarians

The Texas Heart Institute Journal

Paravalvular leaks are well-recognized sequelae of mechanical aortic valve implantation. Clinical manifestations include hemolysis, arrhythmias, and congestive heart failure. Frequently, patients who receive mechanical aortic valves are poor candidates for repeat valve surgery, and the reoperative mortality rate is high. Percutaneous intervention has recently become an alternative to surgery in selected patients. Herein, we describe the percutaneous closure of an aortic paravalvular leak in a 45-year-old man who had undergone 2 aortic valve replacements with mechanical valves. The patient, who was at high surgical risk due to comorbidities, underwent the implantation of 2 AMPLATZER devices with the use of real-time …

Journal Articles: Epidemiology

BACKGROUND AND METHODS: Active duty US Army and Air Force military personnel undergo mandatory biennial HIV antibody screening. We compared pre- and post-HIV seroconversion health status by conducting a case-control study, which evaluated all medical encounters and sociodemographic factors among incident HIV seroconverters and HIV-negative controls from June 2000 through February 2004.

RESULTS: A total of 274 HIV seroconverters and 6205 HIV-negative personnel were included. In multivariate analysis restricted to male personnel (cases = 261, controls = 5801), single marital status (adjusted odds ratio [AOR] = 14.37), clinical indicators or symptoms within four years of HIV diagnosis (AOR = 6.22), …

Left Atrial Ablation For Atrial Fibrillation: Creating The “Box Lesion” With A Bipolar Radiofrequency Device, Leonid Sternik, Hartzel V Schaff, David Luria, Michael Glikson, Alexander Kogan, Ateret Malachy, Maya First, Ehud Raanani

The Texas Heart Institute Journal

The maze procedure is the gold standard for the ablation of atrial fibrillation, and the “box lesion” around the pulmonary veins is the most important part of this procedure. We have created this lesion with a bipolar radiofrequency ablator, abandoning the usual use of this device (to achieve bilateral epicardial isolation of the pulmonary veins).

From March 2004 through the end of May 2010, we performed surgical ablation of atrial fibrillation in 240 patients. Of this number, 205 underwent operation by a hybrid maze technique and the remaining 35 (our study cohort) underwent the creation of a box lesion around …

Prehypertension: A Meta-Analysis Of The Epidemiology, Risk Factors, And Predictors Of Progression, Xiaofan Guo, Liling Zou, Xingang Zhang, Jue Li, Liqiang Zheng, Zhaoqing Sun, Jian Hu, Nathan D Wong, Yingxian Sun

The Texas Heart Institute Journal

We investigated the prevalence and risk factors of prehypertension, as well as the predictors of progression from prehypertension to hypertension. To do this, we performed a systematic review and meta-analysis of cross-sectional and longitudinal studies, after unrestricted searches of PubMed and The Cochrane Library through September 2010. In addition, we reviewed references, major textbooks, and review articles. Pooled prevalence, standardized mean differences, and odds ratios were estimated by using a random-effects model.

Twenty-six articles met our inclusion criteria; these included 20 cross-sectional and 6 longitudinal studies, with a total sample of 250,741 individuals. The overall pooled prevalence of prehypertension was …

The Texas Heart Institute Journal

Takayasu arteritis is an inflammatory condition that involves the large cardiac vessels, predominantly the aorta and its main branches. It typically affects young women (age, ≤40 yr), most often Asians and Latin Americans. Herein, we describe a rare manifestation of Takayasu arteritis in a 19-year-old black Tunisian man who presented with acute inferior myocardial infarction and complete atrioventricular block after occlusion from a giant aneurysm in the right coronary artery. The coronary artery disease was associated with aneurysmal dilations in the carotid, vertebral, and right renal arteries. Medical therapy improved Thrombolysis in Myocardial Infarction flow in the area of the …

Endovascular Repair Of Aortoesophageal And Aortobronchial Fistulae, Roberto Chiesa, Andrea Kahlberg, Yamume Tshomba, Enrico M Marone, Massimiliano M Marrocco-Trischitta, Germano Melissano

The Texas Heart Institute Journal

Aortoesophageal fistulae (AEF) and aortobronchial fistulae (ABF) are uncommon, but are in general fatal if left untreated. Conventional treatment requires surgical replacement of the thoracic aorta, along with several adjunctive procedures to repair the esophageal or tracheobronchial lesion.The mortality rates associated with open surgery reach 61% in cases of primary fistula and 78% in secondary fistula.

Thoracic endovascular aortic repair (TEVAR) has been proposed as an alternative strategy to surgical management.Although less invasive, this technique has important limitations in treating AEF and ABF, the chief of which is the high risk of graft contamination. Moreover, we still lack sufficient data …

Sirolimus-Eluting Stents Versus Bare-Metal Stents In Routine Clinical Use, Muhammad Munir, Jonathan Aliota, Amany Ahmed, Anwarullah Mohammed, Vei Vei Lee, Macarthur A Elayda, James M Wilson

The Texas Heart Institute Journal

Conflicting patient outcomes have been reported after the use of sirolimus-eluting stents or bare-metal stents. In this nonrandomized study, we examine the outcomes after placement of sirolimus-eluting versus bare-metal stents in an unselected population of patients who underwent percutaneous coronary revascularization.

We used THIRD-base, a longitudinal data registry of patients who underwent revascularization at our institution, to compare demographics and outcomes in patients treated with a sirolimus-eluting or bare-metal stent from January 2001 through June 2006. Outcome measures included major acute coronary and cerebral events at 30 days, target-vessel failure at 9 months and at 3 years, and stent thrombosis. …

A Dosing Study Of Bone Marrow Mononuclear Cells For Transendocardial Injection In A Pig Model Of Chronic Ischemic Heart Disease, Guilherme V Silva, Marlos R Fernandes, Cristiano O Cardoso, Ricardo R Sanz, Edie M Oliveira, Pilar Jimenez-Quevedo, Javier Lopez, Franca S Angeli, Yi Zheng, James T Willerson, Emerson C Perin

The Texas Heart Institute Journal

We studied the effect of the dose of bone marrow mononuclear cells, delivered via transendocardial injection, upon capillary density and fibrosis in pigs with chronic ischemic heart disease.

Pigs (n = 16) that had undergone ameroid constrictor placement (left circumflex coronary artery) to induce chronic ischemia were divided equally into 4 groups on the basis of bone marrow mononuclear cell dose: control (saline injection) and 50, 100, or 200 × 106 bone marrow mononuclear cells. Thirty days after ameroid placement, each pig received 13 transendocardial NOGA-guided injections. An implantable loop recorder monitored possible arrhythmias caused by cell transplantation. Thirty days …

Movements Of White-Tailed Deer In Riparian Habitat: Implications For Infectious Diseases, Gregory M. Clements, Scott E. Hygnstrom, Jason M. Gilsdorf, David M. Baasch, Myndi J. Clements, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

Movements of male white-tailed deer (Odocoileus virginianus) are of great concern with respect to spread of chronic wasting disease (CWD) across landscapes because most yearlings males disperse and adult males have higher prevalence of CWD than do females and younger deer. We radio-collared and monitored 85 male white-tailed deer in the middle Missouri River Valley of eastern Nebraska and western Iowa, USA from 2004 to 2008. Average size (±SE) of fixed-kernel annual home ranges (95%) and core areas (50%) for resident deer were 449 (±32) ha and 99 (±7) ha, respectively. Resident deer exhibited a high degree of …

Referrals To A Regional Allergy Clinic - An Eleven Year Audit., Ray B. Jones, Paul Hewson, Edward R. Kaminski

School of Nursing and Midwifery

BACKGROUND: Allergy is a serious and apparently increasing public health problem yet relatively little is known about the types of allergy seen in routine tertiary practice, including their spatial distribution, co-occurrence or referral patterns. This study reviewed referrals over an eleven year period to a regional allergy clinic that had a well defined geographical boundary. For those patients confirmed as having an allergy we explored: (i) differences over time and by demographics, (ii) types of allergy, (iii) co-occurrence, and (iv) spatial distributions. METHODS: Data were extracted from consultant letters to GPs, from September 1998 to September 2009, for patients confirmed …

Midazolam Inhibits Hippocampal Long-Term Potentiation And Learning Through Dual Central And Peripheral Benzodiazepine Receptor Activation And Neurosteroidogenesis, Kazuhiro Tokuda, Kazuko A. O'Dell, Yukitoshi Izumi, Charles F. Zorumski

Open Access Publications

Benzodiazepines (BDZs) enhance GABA(A) receptor inhibition by direct actions on central BDZ receptors (CBRs). Although some BDZs also bind mitochondrial receptors [translocator protein (18 kDa) (TSPO)] and promote the synthesis of GABA-enhancing neurosteroids, the role of neurosteroids in the clinical effects of BDZs is unknown. In rat hippocampal slices, we compared midazolam, an anesthetic BDZ, with clonazepam, an anticonvulsant/anxiolytic BDZ that activates CBRs selectively. Midazolam, but not clonazepam, increased neurosteroid levels in CA1 pyramidal neurons without changing TSPO immunostaining. Midazolam, but not clonazepam, also augmented a form of spike inhibition after stimulation adjacent to the pyramidal cell layer and inhibited …

Golgi Cells Operate As State-Specific Temporal Filters At The Input Stage Of The Cerebellar Cortex, Shane A. Heine, Stephen M. Highstein, Pablo M. Blazquez

Open Access Publications

Cerebellar processing of incoming information begins at the synapse between mossy fibers and granule cells, a synapse that is strongly controlled through Golgi cell inhibition. Thus, Golgi cells are uniquely positioned to control the flow of information into the cerebellar cortex and understanding their responses during behavior is essential to understanding cerebellar function. Here we show, for the first time, that Golgi cells express a unique oculomotor-related signal that can be used to provide state- and time-specific filtering of granule cell activity. We used newly established criteria to identify the unique electrophysiological signature of Golgi cells and recorded these neurons …

Prospective Evaluation Of A Cognitive Vulnerability-Stress Model For Depression: The Interaction Of Schema Self-Structures And Negative Life Events., Pamela M Seeds, David J A Dozois

Psychology Publications

This study tested the diathesis-stress component of Beck's (1967) cognitive theory of depression. Initially, participants completed measures assessing cognitive organization of the self-schema and depressive symptoms. One year later, participants completed measures assessing cognitive organization of the self-schema, depressive symptoms, and negative life events. Hierarchical multiple regression analyses, controlling for initial depression, indicated that more tightly interconnected negative content was associated with greater elevations in depressive symptoms following the occurrence of life events. More diffusely interconnected positive content for interpersonal self-referent information also interacted with life events to predict depressive symptoms. Cognitive organization dimensions showed moderate to high stability across …

A New Species Of Cyclobulura (Nematoda: Subuluridae) From Zaedyus Pichiy And Chaetophractus Vellerosus (Xenarthra: Dasypodidae) In Argentina, Graciela T Navone, María C Ezquiaga, Juliana Notarnicola, F Agustín Jiménez-Ruiz

Publications

Cyclobulura superinae n. sp. collected from Zaedyus pichiy and Chaetophractus vellerosus is herein described as the second species in Cyclobulura Quentin, 1977, and the first subulurid in armadillos. The species is unique in the spur-like structures present at the tip of both spicules, yet they conform to the description of Cyclobulura in the structure of the buccal parts. Specimens of the new species show longer chordal lobes and more conspicuous radial lobes and are smaller than specimens of C. lainsoni. In addition, males of C. superinae exhibit a spur-like process in the distal end of the spicules and a shorter …

The effects of the nondominant or secondary ventricle on the Fontan circulation are not known. The present study used cardiac magnetic resonance imaging to investigate the relations between secondary ventricular size and global cardiac performance. The Fontan cross-sectional study collected data from 7 centers participating in the Pediatric Heart Network. Subjects with complete cardiac magnetic resonance imaging data and an identifiable secondary ventricle were included in the analysis. Relationships between body surface area-adjusted parameters of the secondary ventricle (mass, end-diastolic volume, mass/volume ratio, and stroke volume) and the following measures were assessed. These measures included the percentage of predicted peak …

Acetate Causes Alcohol Hangover Headache In Rats., Christina R Maxwell, Rebecca Jay Spangenberg, Jan B Hoek, Stephen D Silberstein, Michael L Oshinsky

Department of Neurology Faculty Papers

BACKGROUND: The mechanism of veisalgia cephalgia or hangover headache is unknown. Despite a lack of mechanistic studies, there are a number of theories positing congeners, dehydration, or the ethanol metabolite acetaldehyde as causes of hangover headache.

METHODS: We used a chronic headache model to examine how pure ethanol produces increased sensitivity for nociceptive behaviors in normally hydrated rats.

RESULTS: Ethanol initially decreased sensitivity to mechanical stimuli on the face (analgesia), followed 4 to 6 hours later by inflammatory pain. Inhibiting alcohol dehydrogenase extended the analgesia whereas inhibiting aldehyde dehydrogenase decreased analgesia. Neither treatment had nociceptive effects. Direct administration of acetate …

Incidence Of, Predictors For, And Mortality Associated With Malignant Ventricular Arrhythmias In Non-St Elevation Myocardial Infarction Patients., Shuchita Gupta, Md, Gregg S. Pressman, Vincent M. Figueredo, M.D.

Division of Cardiology Faculty Papers

BACKGROUND: The incidence of non-ST elevation myocardial infarction (NSTEMI) is increasing. Although life-threatening ventricular arrhythmias have been well-documented in patients with ST elevation MI (STEMI), their incidence and importance in NSTEMI have not been examined in similar detail. We examined the incidence, predictors, and mortality rates of ventricular arrhythmias in a cohort of NSTEMI patients undergoing an early invasive strategy.

METHODS: Consecutive patients admitted with NSTEMI who underwent cardiac catheterization within 48 h of admission were identified by chart review. Presence and type of ventricular arrhythmias and 30-day mortality were recorded. Malignant arrhythmias were defined as sustained ventricular tachycardia (VT, …

Calcium Regulates Vesicle Replenishment At The Cone Ribbon Synapse., Norbert Babai, Theodore M. Bartoletti, Wallace B. Thoreson

Journal Articles: Ophthalmology

Cones release glutamate-filled vesicles continuously in darkness, and changing illumination modulates this release. Because sustained release in darkness is governed by vesicle replenishment rates, we analyzed how cone membrane potential regulates replenishment. Synaptic release from cones was measured by recording postsynaptic currents in Ambystoma tigrinum horizontal or OFF bipolar cells evoked by depolarization of simultaneously voltage-clamped cones. We measured replenishment after attaining a steady state between vesicle release and replenishment using trains of test pulses. Increasing Ca(2+) currents (I(Ca)) by changing the test step from -30 to -10 mV increased replenishment. Lengthening -30 mV test pulses to match the Ca(2+) …

Biparental Mucus Feeding: A Unique Example Of Parental Care In An Amazonian Cichlid., Jonathan Buckley, Richard J. Maunder, Andrew Foey, Janet Pearce, Adalberto L. Val, Katherine A. Sloman

School of Biomedical Sciences

Vertebrates display a wide variety of parental care behaviours, including the guarding of offspring pre and post nutritional independence as well as the direct provision of nutrients during the early development period. The Amazonian cichlid Symphysodon spp. (discus fish) is unusual among fish species, in that both parents provide offspring with mucus secretions to feed from after hatching. This extensive provision of care, which can last up to a month, imposes a physiological demand on both parents and gives rise to conflict between the parent and offspring. Here, we investigated the relationship between parents and offspring during a breeding cycle, …

T-Lymphocyte Responses To Intestinally Absorbed Antigens Can Contribute To Adipose Tissue Inflammation And Glucose Intolerance During High Fat Feeding, Yuehui Wang, Jianing Li, Lihua Tang, Yu Wang, Richard Charnigo, Willem De Villiers, Erik Eckhardt

Internal Medicine Faculty Publications

BACKGROUND: Obesity is associated with inflammation of visceral adipose tissues, which increases the risk for insulin resistance. Animal models suggest that T-lymphocyte infiltration is an important early step, although it is unclear why these cells are attracted. We have recently demonstrated that dietary triglycerides, major components of high fat diets, promote intestinal absorption of a protein antigen (ovalbumin, "OVA"). The antigen was partly transported on chylomicrons, which are prominently cleared in adipose tissues. We hypothesized that intestinally absorbed gut antigens may cause T-lymphocyte associated inflammation in adipose tissue.

METHODOLOGY/PRINCIPAL FINDINGS: Triglyceride absorption promoted intestinal absorption of OVA into adipose tissue, …

Chronic Spontaneous Activity Generated In The Somata Of Primary Nociceptors Is Associated With Pain-Related Behavior After Spinal Cord Injury, Supinder S Bedi, Qing Yang, Robyn J Crook, Junhui Du, Zizhen Wu, Harvey M Fishman, Raymond J Grill, Susan M Carlton, Edgar T Walters

Faculty, Staff and Student Publications

Mechanisms underlying chronic pain that develops after spinal cord injury (SCI) are incompletely understood. Most research on SCI pain mechanisms has focused on neuronal alterations within pain pathways at spinal and supraspinal levels associated with inflammation and glial activation. These events might also impact central processes of primary sensory neurons, triggering in nociceptors a hyperexcitable state and spontaneous activity (SA) that drive behavioral hypersensitivity and pain. SCI can sensitize peripheral fibers of nociceptors and promote peripheral SA, but whether these effects are driven by extrinsic alterations in surrounding tissue or are intrinsic to the nociceptor, and whether similar SA occurs …

Wild-Type And Mutant Sod1 Share An Aberrant Conformation And A Common Pathogenic Pathway In Als., Daryl A Bosco, Gerardo Morfini, N Murat Karabacak, Yuyu Song, Francois Gros-Louis, Piera Pasinelli, Holly Goolsby, Benjamin A Fontaine, Nathan Lemay, Diane Mckenna-Yasek, Matthew P Frosch, Jeffrey N Agar, Jean-Pierre Julien, Scott T Brady, Robert H Brown

Farber Institute for Neuroscience Faculty Papers

Many mutations confer one or more toxic function(s) on copper/zinc superoxide dismutase 1 (SOD1) that impair motor neuron viability and cause familial amyotrophic lateral sclerosis (FALS). Using a conformation-specific antibody that detects misfolded SOD1 (C4F6), we found that oxidized wild-type SOD1 and mutant SOD1 share a conformational epitope that is not present in normal wild-type SOD1. In a subset of human sporadic ALS (SALS) cases, motor neurons in the lumbosacral spinal cord were markedly C4F6 immunoreactive, indicating that an aberrant wild-type SOD1 species was present. Recombinant, oxidized wild-type SOD1 and wild-type SOD1 immunopurified from SALS tissues inhibited kinesin-based fast axonal …

Should We Be Concerned About Jejunoileal Atresia During Repair Of Duodenal Atresia?, Shawn D. St Peter, Danny C. Little, Katherine A. Barsness, Daniel R. Copeland, Casey M. Calkins, Suzanne Yoder, Steve S. Rothenberg, Saleem Islam, Kuojen Tsao, Daniel J. Ostlie

Manuscripts, Articles, Book Chapters and Other Papers

INTRODUCTION: During repair for duodenal atresia, it has been emphasized that inspection of the small bowel to identify a second atresia is required. The laparoscopic approach for repair of duodenal atresia has been criticized for its limitation to perform this step. Given that duodenal atresia and jejunoileal atresias do not share common embryologic origins, we question the validity of this concern. Therefore, we conducted a multicenter retrospective review of duodenal atresia patients to quantify the incidence of jejunoileal atresia in this population.

METHODS: After institutional review board approval (IRB #07-12-187X), a retrospective review was conducted on all patients who have …
