Coronary Artery Diameter Related To Calcium Scores And Coronary Risk Factors As Measured With Multidetector Computed Tomography: A Substudy Of The Accuracy Trial, Yasmin S Hamirani, Khurram Nasir, Emil Avanes, Jigar Kadakia, Matthew J Budoff

The Texas Heart Institute Journal

Arterial remodeling, an early change of atherosclerosis, can cause dilated arterial diameter. We measured coronary artery diameter with use of noncontrast 64-slice multidetector computed tomography (MDCT), and studied its association with coronary artery calcium levels and traditional coronary risk factors.

We included 140 patients from the ACCURACY trial whose noncontrast MDCT images showed measurable coronary arteries. Using 3 measurements of left main coronary artery (LMCA) and right coronary artery (RCA) diameters within 3 mm of the ostium, we associated the results with traditional coronary risk factors and calcium scores.

The prevalence of LMCA and RCA calcium was 22% and 51%, …

Preventing Sudden Cardiac Death In Athletes: In Search Of Evidence-Based, Cost-Effective Screening, Paolo Angelini, Mladen I Vidovich, Christine E Lawless, Macarthur A Elayda, J Alberto Lopez, Dwayne Wolf, James T Willerson

The Texas Heart Institute Journal

Sudden cardiac death in athletes is a recurrent phenomenon at sporting events and during training. Recent studies have associated sudden cardiac death with such cardiovascular conditions as coronary artery anomalies, cardiomyopathies, and electrocardiographic abnormalities, most of which are screenable with modern imaging techniques. We recently inaugurated the Center for Coronary Artery Anomalies at the Texas Heart Institute, which is dedicated to preventing sudden cardiac death in the young and investigating coronary artery anomalies. There, we are conducting 2 cross-sectional studies intended to firmly establish and quantify, in a large group of individuals from a general population, risk factors for sudden …

Stab Wound Of The Heart With Unusual Sequelae, Peter I Praeger, Jonathan Praeger, Ahmed M Abdel-Razek, Elie M Elmann

The Texas Heart Institute Journal

A 31-year-old woman was admitted to the emergency department with a stab wound to the heart. She was initially stable but rapidly developed hypotension. While the operating room and staff were in preparation, she underwent pericardiocentesis. She was then rushed to the operating room by the general surgical trauma team, who performed a bilateral anterior thoracotomy to control the bleeding. In the recovery room, the patient was still hypotensive, so cardiothoracic surgery was consulted.

An echocardiogram revealed severe hypokinesis of both ventricles. The cardiothoracic surgeons returned her to the operating room and discovered that the anterior pericardium had been completely …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The literature reports the efficacy of the laparoscopic approach to paraesophageal hiatal hernia repair. However, its adoption as the preferred surgical approach and the risks associated with paraesophageal hiatal hernia repair have not been reviewed in a large database.

METHOD: The Nationwide Inpatient Sample dataset was queried from 1998 to 2005 for patients who underwent repair of a complicated (the entire stomach moves into the chest cavity) versus uncomplicated (only the upper part of the stomach protrudes into the chest) paraesophageal hiatal hernia via the laparoscopic, open abdominal, or open thoracic approach. A multivariate analysis was performed controlling for …

Learning Medical Alarms Whilst Performing Other Tasks., Judy Edworthy, Christina Meredith, Elizabeth Hellier, David Rose

School of Psychology

UNLABELLED: Two studies are reported which first observe, and then attempt to replicate, the cognitive demands of intensive care unit (ICU) activity whilst concurrently learning audible alarms. The first study, an observational study in an ICU ward, showed that the alarms are very frequent and co-occur with some activities more than others. The three most frequently observed activities observed in the ICU were drugs (calculation, preparation and administration), patient observation and talking. The cognitive demands of these activities were simulated in a second, laboratory-based experiment in which alarms were learned. The results showed that performance in the alarm task generally …

Tucker, Alisa M. Goldstein, Jeffrey E. Lee, Qingyi Wei, Sharon A. Savage, Xiaohong R. Yang, Christopher Amos, Maria Teresa Landi

Dartmouth Scholarship

The relationship between telomeres, nevi and melanoma is complex. Shorter telomeres have been found to be associated with many cancers and with number of nevi, a known risk factor for melanoma. However, shorter telomeres have also been found to decrease melanoma risk. We performed a systematic analysis of telomere-related genes and tagSNPs within these genes, in relation to the risk of melanoma, dysplastic nevi, and nevus count combining data from four studies conducted in Italy. In addition, we examined whether telomere length measured in peripheral blood leukocytes is related to the risk of melanoma, dysplastic nevi, number of nevi, or …

Pharmacy Practice and Science Faculty Publications

The emergence of Klebsiella pneumoniae carbapenemases (KPCs) producing bacteria has become a significant global public health challenge while the optimal treatment remains undefined. We performed a systematic review of published studies and reports of treatment outcomes of KPC infections using MEDLINE (2001-2011). Articles or cases were excluded if one of the following was fulfilled: no individual patient data provided, no treatment regimen specified, no treatment outcome specified, report of colonization, or greater than three antibiotics were used to treat the KPC infection. Data extracted included patient demographics, site of infection, organism, KPC subtype, antimicrobial therapy directed at KPC-infection, and treatment …

Reactive Oxygen Species Production And Brugia Pahangi Survivorship In Aedes Polynesiensis With Artificial Wolbachia Infection Types, Elizabeth S. Andrews, Philip R. Crain, Yuqing Fu, Daniel K. Howe, Stephen L. Dobson

Entomology Faculty Publications

Heterologous transinfection with the endosymbiotic bacterium Wolbachia has been shown previously to induce pathogen interference phenotypes in mosquito hosts. Here we examine an artificially infected strain of Aedes polynesiensis, the primary vector of Wuchereria bancrofti, which is the causative agent of Lymphatic filariasis (LF) throughout much of the South Pacific. Embryonic microinjection was used to transfer the wAlbB infection from Aedes albopictus into an aposymbiotic strain of Ae. polynesiensis. The resulting strain (designated "MTB") experiences a stable artificial infection with high maternal inheritance. Reciprocal crosses of MTB with naturally infected wild-type Ae. polynesiensis demonstrate strong bidirectional incompatibility. Levels of reactive …

BACKGROUND: Intimate partner violence (IPV) is prevalent among adolescent and adult women, with significant physical, sexual, and mental health consequences. In 2011, the Institute of Medicine's Clinical Preventive Services for Women consensus report recommended universal screening for violence as a component of women's preventive services; this policy has been adopted by the Health Resources and Services Administration (HRSA). These policy developments require that effective clinic-based interventions be identified, easily implemented, and taken to scale.

METHODS: To foster dialogue about implementing effective interventions, we convened a symposium entitled "Responding to Violence Against Women: Emerging Evidence, Implementation Science, and Innovative Interventions," on …

Process And Domain Specificity In Regions Engaged For Face Processing: An Fmri Study Of Perceptual Differentiation, Heather R. Collins, Xun Zhu, Ramesh S. Bhatt, Jonathan D. Clark, Jane E. Joseph

Psychology Faculty Publications

The degree to which face-specific brain regions are specialized for different kinds of perceptual processing is debated. This study parametrically varied demands on featural, first-order configural, or second-order configural processing of faces and houses in a perceptual matching task to determine the extent to which the process of perceptual differentiation was selective for faces regardless of processing type (domain-specific account), specialized for specific types of perceptual processing regardless of category (process-specific account), engaged in category-optimized processing (i.e., configural face processing or featural house processing), or reflected generalized perceptual differentiation (i.e., differentiation that crosses category and processing type boundaries). ROIs were …

Intersecting Identities Of Female College Student Intramural Sports Officials: A Grounded Theory, April Flint

All Dissertations

Intramural activities are conducted on virtually every college campus throughout the United States, but there is a debate as to the role of intramurals in the overall development of the student (Rothwell & Theodore, 2006). Specifically for females, not every sport is offered for participation at youth or higher levels, but intramural sports is one arena where they have the chance to learn the sport rules and referee the game. This study aims to create a base of knowledge on the experiences of female college students who work on campus as intramural sports officials. The purpose of the study is …

Necrostatin-1 Analogues: Critical Issues On The Specificity, Activity And In Vivo Use In Experimental Disease Models., N Takahashi, L Duprez, S Grootjans, A Cauwels, W Nerinckx, J B Duhadaway, V Goossens, R Roelandt, F Van Hauwermeiren, C Libert, W Declercq, N Callewaert, G C Prendergast, A Degterev, J Yuan, P Vandenabeele

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Necrostatin-1 (Nec-1) is widely used in disease models to examine the contribution of receptor-interacting protein kinase (RIPK) 1 in cell death and inflammation. We studied three Nec-1 analogs: Nec-1, the active inhibitor of RIPK1, Nec-1 inactive (Nec-1i), its inactive variant, and Nec-1 stable (Nec-1s), its more stable variant. We report that Nec-1 is identical to methyl-thiohydantoin-tryptophan, an inhibitor of the potent immunomodulatory enzyme indoleamine 2,3-dioxygenase (IDO). Both Nec-1 and Nec-1i inhibited human IDO, but Nec-1s did not, as predicted by molecular modeling. Therefore, Nec-1s is a more specific RIPK1 inhibitor lacking the IDO-targeting effect. Next, although Nec-1i was ∼100 × …

Frequent Arousals From Winter Torpor In Rafinesque's Big-Eared Bat (Corynorhinus Rafinesquii), Joseph S. Johnson, Michael J. Lacki, Steven C. Thomas, John F. Grider

Forestry and Natural Resources Faculty Publications

Extensive use of torpor is a common winter survival strategy among bats; however, data comparing various torpor behaviors among species are scarce. Winter torpor behaviors are likely to vary among species with different physiologies and species inhabiting different regional climates. Understanding these differences may be important in identifying differing susceptibilities of species to white-nose syndrome (WNS) in North America. We fitted 24 Rafinesque’s big-eared bats (Corynorhinus rafinesquii) with temperature-sensitive radio-transmitters, and monitored 128 PIT-tagged big-eared bats, during the winter months of 2010 to 2012. We tested the hypothesis that Rafinesque’s big-eared bats use torpor less often than values …

Multivitamin Supplementation In Hiv Infected Adults Initiating Antiretroviral Therapy In Uganda: The Protocol For A Randomized Double Blinded Placebo Controlled Efficacy Trial., David Guwatudde, Amara E. Ezeamama, Danstan Bagenda, Rachel Kyeyune, Fred Wabwire-Mangen, Henry Wamani, Ferdinand Mugusi, Donna Spiegelman, Molin Wang, Yukari C. Manabe, Wafaie W. Fawzi

Journal Articles: Epidemiology

BACKGROUND: Use of multivitamin supplements during the pre-HAART era has been found to reduce viral load, enhance immune response, and generally improve clinical outcomes among HIV-infected adults. However, immune reconstitution is incomplete and significant mortality and opportunistic infections occur in spite of HAART. There is insufficient research information on whether multivitamin supplementation may be beneficial as adjunct therapy for HIV-infected individuals taking HAART. We propose to evaluate the efficacy of a single recommended daily allowance (RDA) of micronutrients (including vitamins B-complex, C, and E) in slowing disease progression among HIV-infected adults receiving HAART in Uganda.

METHODS/DESIGN: We are using a …

Open Release Of Male Mosquitoes Infected With A Wolbachia Biopesticide: Field Performance And Infection Containment, Linda O'Connor, Catherine Plichart, Ayo Cheong Sang, Corey L. Brelsfoard, Hervé C. Bossin, Stephen L. Dobson

Entomology Faculty Publications

BACKGROUND: Lymphatic filariasis (LF) is a globally significant disease, with 1.3 billion persons in 83 countries at risk. A coordinated effort of administering annual macrofilaricidal prophylactics to the entire at-risk population has succeeded in impacting and eliminating LF transmission in multiple regions. However, some areas in the South Pacific are predicted to persist as transmission sites, due in part to the biology of the mosquito vector, which has led to a call for additional tools to augment drug treatments. Autocidal strategies against mosquitoes are resurging in the effort against invasive mosquitoes and vector borne disease, with examples that include field …

Escherichia Coli-Mediated Impairment Of Ureteric Contractility Is Uropathogenic E. Coli Specific., Rachel V. Floyd, Mathew Upton, Scott J. Hultgren, Susan Wray, Theodor V. Burdyga, Craig Winstanley

School of Biomedical Sciences

BACKGROUND: Ureters are fundamental for keeping kidneys free from uropathogenic Escherichia coli (UPEC), but we have shown that 2 strains (J96 and 536) can subvert this role and reduce ureteric contractility. To determine whether this is (1) a widespread feature of UPEC, (2) exhibited only by UPEC, and (3) dependent upon type 1 fimbriae, we analyzed strains representing epidemiologically important multilocus sequence types ST131, ST73, and ST95 and non-UPEC E. coli. METHODS: Contractility and calcium transients in intact rat ureters were compared between strains. Mannose and fim mutants were used to investigate the role of type 1 fimbriae. RESULTS: Non-UPEC …

Muc4 And Muc1 Expression In Adenocarcinoma Of The Stomach Correlates With Vessel Invasion And Lymph Node Metastasis: An Immunohistochemical Study Of Early Gastric Cancer., Yukihiro Tamura, Michiyo Higashi, Sho Kitamoto, Seiya Yokoyama, Masahiko Osako, Michiko Horinouchi, Takeshi Shimizu, Mineo Tabata, Surinder K. Batra, Masamichi Goto, Suguru Yonezawa

Journal Articles: Biochemistry & Molecular Biology

We have previously reported that MUC4 expression is a poor prognostic factor in various carcinomas. Our previous study also showed that MUC1 expression in gastric cancers, including the early and advanced stages is a poor prognostic factor. In the present study, the expression profiles of MUC4 and MUC1 were examined by immunohistochemistry (IHC) using two anti-MUC4 monoclonal antibodies (MAbs), 8G7 and 1G8, and anti-MUC1 MAb DF3 in 104 gastrectomy specimens of early gastric adenocarcinoma with submucosal invasion (pT1b2), including 197 histological subtype lesions. Before the IHC study of the human specimens, we evaluated the specificity of the two MAbs by …

Wolbachia Strain Wpip Yields A Pattern Of Cytoplasmic Incompatibility Enhancing A Wolbachia-Based Suppression Strategy Against The Disease Vector Aedes Albopictus, Maurizio Calvitti, Riccardo Moretti, Amanda R. Skidmore, Stephen L. Dobson

Entomology Faculty Publications

BACKGROUND: Cytoplasmic incompatibility (CI) is induced in nature by Wolbachia bacteria, resulting in conditional male sterility. Previous research demonstrated that the two Wolbachia strains (wAlbA and wAlbB) that naturally co-infect the disease vector mosquito Aedes albopictus (Asian tiger mosquito) can be replaced with the wPip Wolbachia strain from Culex pipiens. Since Wolbachia-based vector control strategies depend upon the strength and consistency of CI, a greater understanding is needed on the CI relationships between wPip, wAlbA and wAlbB Wolbachia in Ae. albopictus.

METHODS: This work consisted of a collaborative series of crosses carried out in Italy and in US to study …
