Bioresorbable Scaffolds In Spontaneous Coronary Artery Dissection: Long-Term Follow-Up In 4 Patients, Santiago Jesús Camacho Freire, Antonio Enrique Gómez Menchero, Jessica Roa Garrido, Javier León Jiménez, Rosa Cardenal Piris, José Francisco Díaz Fernández

The Texas Heart Institute Journal

Spontaneous coronary artery dissection is a rare condition, and diagnosis and treatment are challenging among patients who present with acute coronary syndrome. Typically, the condition affects young females who have no underlying atherosclerotic disease. To date, few cases of bioresorbable scaffold implantation for the treatment of spontaneous coronary artery dissection have been reported. Therefore, we describe the cases of 4 patients whom we treated with scaffolds. We evaluated the long-term results by using intravascular ultrasound and optical coherence tomographic scanning.

Linkage, Whole Genome Sequence, And Biological Data Implicate Variants In Rab10 In Alzheimer's Disease Resilience., Perry G Ridge, Celeste M Karch, Simon Hsu, Ivan Arano, Craig C Teerlink, Mark T W Ebbert, Josue D Gonzalez Murcia, James M Farnham, Anna R Damato, Mariet Allen, Xue Wang, Oscar Harari, Victoria M Fernandez, Rita Guerreiro, Jose Bras, John Hardy, Ronald Munger, Maria Norton, Celeste Sassi, Andrew Singleton, Steven G Younkin, Dennis W Dickson, Todd E Golde, Nathan D Price, Nilüfer Ertekin-Taner, Carlos Cruchaga, Alison M Goate, Christopher Corcoran, Joann Tschanz, Lisa A Cannon-Albright, John S K Kauwe

BACKGROUND: While age and the APOE ε4 allele are major risk factors for Alzheimer's disease (AD), a small percentage of individuals with these risk factors exhibit AD resilience by living well beyond 75 years of age without any clinical symptoms of cognitive decline.

METHODS: We used over 200 "AD resilient" individuals and an innovative, pedigree-based approach to identify genetic variants that segregate with AD resilience. First, we performed linkage analyses in pedigrees with resilient individuals and a statistical excess of AD deaths. Second, we used whole genome sequences to identify candidate SNPs in significant linkage regions. Third, we replicated SNPs …

Noninvasive Liquid Diet Delivery Of Stable Isotopes Into Mouse Models For Deep Metabolic Network Tracing, Ramon C. Sun, Teresa W.-M. Fan, Pan Deng, Richard M. Higashi, Andrew N. Lane, Anh-Thu Le, Timothy L. Scott, Qiushi Sun, Marc O. Warmoes, Ye Yang

Center for Environmental and Systems Biochemistry Faculty Publications

Delivering isotopic tracers for metabolic studies in rodents without overt stress is challenging. Current methods achieve low label enrichment in proteins and lipids. Here, we report noninvasive introduction of ¹³C₆-glucose via a stress-free, ad libitum liquid diet. Using NMR and ion chromatography-mass spectrometry, we quantify extensive ¹³C enrichment in products of glycolysis, the Krebs cycle, the pentose phosphate pathway, nucleobases, UDP-sugars, glycogen, lipids, and proteins in mouse tissues during 12 to 48 h of ¹³C₆-glucose feeding. Applying this approach to patient-derived lung tumor xenografts (PDTX), we show that the liver supplies glucose-derived Gln …

Obstetrics and Gynaecology, East Africa

Background: The INPAC project aims to evaluate the effectiveness of integrated post-abortion family planning (PAFP) services into existing hospital based abortion services in China. A qualitative study was conducted in three provinces to contribute to developing effective PAFP services through understanding influences on contraceptive use, experiences of abortion and existing PAFP, and their effect on future contraceptive practices from the perspective of users, in the context of social and institutional change.

Methods: Twenty-nine in-depth interviews (IDIs) were undertaken with women who had experienced abortion between 1 and 6 months prior to interview, recruited from three urban and two rural facilities …

Targeting Cancer Stem Cells In Recurrent Lung Cancer, Karen T. Udoh

Posters-at-the-Capitol

Lung cancer is the leading cause of cancer mortality in the world. Five-year survivability still remains dismal due to drug resistance. The development of drug resistance with cisplatin or platinum/taxane combination chemotherapies has led patients to suffer from recurrent lung cancer. These chemotherapy treatments target cancer cells but leave behind cancer stem cells. Cancer stem cells (CSCs) are stem-like tumor cells that have the potential to differentiate, self-renew, and proliferate. This allows the cancer to relapse even after initial elimination of the tumor. We hypothesize that Verrucarin J will inhibit cell proliferation in lung cancer cells and CSCs by inducing …

Determinants Of Behavioral Intent To Adopt The Closed-Loop Artificial Pancreas Among Diabetes Healthcare Providers, Carolyn M. Serrano

Seton Hall University Dissertations and Theses (ETDs)

Background and Purpose of the Study: Diabetes mellitus for both children and adults are broadly defined as a group of complex diseases characterized by high blood glucose, resulting from a defect in either the production of or action of insulin, or both (National Institutes of Health, 2014). There are 29.1 million people in the US that are estimated to have diagnosed or undiagnosed diabetes (Centers for Disease Control and Prevention (CDC), 2014). Type 1 diabetes accounts for approximately 5-10% of all diabetes cases however, it has serious short term and long-term implications (Daneman, 2006).

Technology for diabetes management is rapidly …

Reducing Symptom Distress In Patients With Advanced Cancer Using An E-Alert System For Caregivers: Pooled Analysis Of Two Randomized Clinical Trials, David H. Gustafson, Lori L. Dubenske, Amy K. Atwood, Ming-Yuan Chih, Roberta A. Johnson, Fiona Mctavish, Andrew Quanbeck, Roger L. Brown, James F. Cleary, Dhavan Shah

Health and Clinical Sciences Faculty Publications

Background: Symptom distress in patients toward the end of life can change rapidly. Family caregivers have the potential to help patients manage those symptoms, as well as their own stress, if they are equipped with the proper resources. Electronic health (eHealth) systems may be able to provide those resources. Very sick patients may not be able to use such systems themselves to report their symptoms but family caregivers could.

Objective: The aim of this paper was to assess the effects on cancer patient symptom distress of an eHealth system that alerts clinicians to significant changes in the patient’s symptoms, as …

Tumor-associated macrophages (TAM) contribute to all aspects of tumor progression. Use of CSF1R inhibitors to target TAM is therapeutically appealing, but has had very limited anti-tumor effects. Here, we have identified the mechanism that limited the effect of CSF1R targeted therapy. We demonstrated that carcinoma-associated fibroblasts (CAF) are major sources of chemokines that recruit granulocytes to tumors. CSF1 produced by tumor cells caused HDAC2-mediated downregulation of granulocyte-specific chemokine expression in CAF, which limited migration of these cells to tumors. Treatment with CSF1R inhibitors disrupted this crosstalk and triggered a profound increase in granulocyte recruitment to tumors. Combining CSF1R inhibitor with …

A Murine Model For Developmental Dysplasia Of The Hip: Ablation Of Cx3cr1 Affects Acetabular Morphology And Gait., George J. Feldman, Arlene Offemaria, Hind Sawan, Javad Parvizi, Theresa A. Freeman

Rothman Institute Papers

BACKGROUND: Developmental dysplasia of the hip (DDH) is a debilitating condition whose distinguishing signs include incomplete formation of the acetabulum leading to dislocation of the femur, accelerated wear of the articular cartilage and joint laxity resulting in osteoarthritis. It is a complex disorder having environmental and genetic causes. Existing techniques fail to detect milder forms of DDH in newborns leading to hip osteoarthritis in young adults. A sensitive, specific and cost effective test would allow identification of newborns that could be non-invasively corrected by the use of a Pavlik harness. Previously, we identified a 2.5 MB candidate region on human …

Efficacy Of An Adenoviral Vectored Multivalent Centralized Influenza Vaccine, Amy Lingel, Brianna L. Bullard, Eric A. Weaver

Nebraska Center for Virology: Faculty Publications

Mice were immunized with Adenovirus expressing the H1-con, H2-con, H3-con and H5-con HA consensus genes in combination (multivalent) and compared to mice immunized with the traditional 2010–2011 FluZone and FluMist seasonal vaccines. Immunized mice were challenged with 10–100 MLD50 of H1N1, H3N1, H3N2 and H5N1 influenza viruses. The traditional vaccines induced robust levels of HA inhibition (HI) titers, but failed to protect against five different heterologous lethal influenza challenges. Conversely, the multivalent consensus vaccine (1 × 1010 virus particles (vp)/mouse) induced protective HI titers of ≥40 against 8 of 10 influenza viruses that represent a wide degree of divergence within …

Generation Of A Patient-Derived Brain Metastasis Breast Cancer Cell Line Via Novel Orthotopic Injection Placement And Serial Mouse Transplantation To Develop Pdx Mouse Model, Amber L. Lacrosse, Denise M. Coley, Paul J. Mintz, Santhi D. Konduri, Richard A. Rovin, Amin B. Kassam

Journal of Patient-Centered Research and Reviews

Background: The incidence of brain metastasis appears to be increasing, potentially due to advanced technology that aids early diagnosis. Patient-derived xenografts (PDX) have high translational value, as these models retain key functional characteristics of the patient tumor. PDX models are useful to understand the molecular basis of tumorigenesis and to identify new treatment targets. However, generating a first-line PDX model is challenging as engraftment failure is high. Serial transplanting tumor tissue via mouse-to-mouse propagation increases engraftment rates and decreases PDX development time. Herein we report methods to generate a PDX cell line from patient-derived tumor tissue that includes the cerebral …

Journal of Patient-Centered Research and Reviews

Background: Timely administration of broad spectrum antibiotics has been shown to be directly correlated with decreased mortality for patients with severe sepsis and septic shock. As such, both the Surviving Sepsis Campaign and the SEP-1 CMS measure recognize timely antibiotic administration as a cornerstone of therapy for patients with severe sepsis or septic shock.

Purpose: Decrease time to broad spectrum antibiotic administration for septic patients in the emergency department (ED) of Aurora St. Luke’s Medical Center.

Methods: An alert within the electronic medical record was created to more rapidly identify potentially septic patients in the ED. After receiving the alert, …

Sensitivity Of Current Methods For Diagnosing And Documenting Metabolic Syndrome Within A Large Community-Based Health Care System, Tiffany A. Mullen, Danielle M. Greer, Jennifer T. Fink, Renee E. Walker

Journal of Patient-Centered Research and Reviews

Background: Metabolic syndrome (MetS) is a constellation of metabolic conditions, including abdominal obesity, high blood pressure, high triglyceride level, low high-density-lipoprotein level and high fasting blood glucose level, that increase the risk of developing chronic health conditions. Various combinations of diagnostic criteria have been proposed, including those by the National Cholesterol Education Program Adult Treatment Panel III (ATP III), World Health Organization (WHO) and International Diabetes Foundation (IDF), among others. However, inconsistent use of diagnostic criteria and inadequate scientific evidence supporting use of specific criteria are current problems in health care.

Purpose: Quantify the prevalence of MetS diagnosis within the …

Pro-Inflammatory Chemokines And Cytokines Dominate The Blister Fluid Molecular Signature In Patients With Epidermolysis Bullosa And Affect Leukocyte And Stem Cell Migration., Vitali Alexeev, Julio Cesar Salas-Alanis, Francis Palisson, Lila Mukhtarzada, Giulio Fortuna, Jouni Uitto, Andrew P. South, Olga Igoucheva

Department of Dermatology and Cutaneous Biology Faculty Papers

Hereditary epidermolysis bullosa (EB) is associated with skin blistering and the development of chronic nonhealing wounds. Although clinical studies have shown that cell-based therapies improve wound healing, the recruitment of therapeutic cells to blistering skin and to more advanced skin lesions remains a challenge. Here, we analyzed cytokines and chemokines in blister fluids of patients affected by dystrophic, junctional, and simplex EB. Our analysis revealed high levels of CXCR1, CXCR2, CCR2, and CCR4 ligands, particularly dominant in dystrophic and junctional EB. In vitro migration assays demonstrated the preferential recruitment of CCR4⁺ lymphocytes and CXCR1⁺, CXCR2⁺, …

Rationale: Cardiac lipotoxicity, characterized by increased uptake, oxidation and accumulation of lipid intermediates, contributes to cardiac dysfunction in obesity and diabetes. However, mechanisms linking lipid overload and mitochondrial dysfunction are incompletely understood.

Objective: To elucidate the mechanisms for mitochondrial adaptations to lipid overload in postnatal hearts in vivo.

Methods and Results: Using a transgenic mouse model of cardiac lipotoxicity overexpressing long-chain acyl-CoA synthetase 1 in cardiomyocytes, we show that modestly increased myocardial fatty acid uptake leads to mitochondrial structural remodeling with significant reduction in minimum diameter. This is associated with increased palmitoyl-carnitine oxidation and increased reactive oxygen species (ROS) generation …

Mtor Kinase Inhibition Effectively Decreases Progression Of A Subset Of Neuroendocrine Tumors That Progress On Rapalog Therapy And Delays Cardiac Impairment, Melissa A. Orr-Asman, Zhengtao Chu, Min Jiang, Mariah Worley, Kathleen Lesance, Sheryl E. Koch, Vinicius S. Carreira, Hanan M. Dahche, David R. Plas, Kakajan Komurov, Xiaoyang Qi, Carol A. Mercer, Lowell B. Anthony, Jack Rubinstein, Hala E. Thomas

Internal Medicine Faculty Publications

Inhibition of mTOR signaling using the rapalog everolimus is an FDA-approved targeted therapy for patients with lung and gastroenteropancreatic neuroendocrine tumors (NET). However, patients eventually progress on treatment, highlighting the need for additional therapies. We focused on pancreatic NETs (pNET) and reasoned that treatment of these tumors upon progression on rapalog therapy, with an mTOR kinase inhibitor (mTORKi), such as CC-223, could overcome a number of resistance mechanisms in tumors and delay cardiac carcinoid disease. We performed preclinical studies using human pNET cells in vitro and injected them subcutaneously or orthotopically to determine tumor progression and cardiac function in mice …

Shell Effects On Acoustic Performance Of A Drug-Delivery System Activated By Ultrasound., Lauren J Jablonowski, Michael C Cochran, John R. Eisenbrey, Nutte T. Teraphongphom, Margaret A Wheatley

Department of Radiology Faculty Papers

The composition of microcapsules designed for drug delivery significantly impacts their properties. Ultrasound contrast agents, consisting of stabilized microbubbles (MBs), have emerged as versatile potential drug delivery vehicles to both image and overcome challenges associated with systemic chemotherapy. In our development of polylactic acid MBs decorated with immune-shielding polyethylene glycol chains, we have shown that the balance between acoustic behavior and immune avoidance was scalable and amenable to two distinct PEGylation methods, either incorporation of 5 wt% PEGylated PLA or insertion of 1 wt% PEGylated lipid (LipidPEG) in the polymeric shell. Here we describe the effects of shell compositions on …

Usability Of A Smartphone Application To Support The Prevention And Early Intervention Of Anxiety In Youth, Ryan D. Stoll, Armando A. Pina, Kevin Gary, Ashish Amresh

Publications

Anxiety disorders are among the most common psychiatric problems in youth, fail to spontaneously remit, and place some youth at risk for additional behavioral and emotional difficulties. Efforts to target anxiety have resulted in evidence-based interventions but the resulting prevention effects are relatively small, often weakening over time. Mobile health (mHealth) tools could be of use to strengthen the effects of anxiety prevention efforts. Although a large number of mHealth apps have been developed, few have been evaluated in terms of usability prior to clinical effectiveness testing. Because usability is one of the main barriers to mHealth usage and adoption, …

Induction Of Peripheral Tolerance In Ongoing Autoimmune Inflammation Requires Interleukin 27 Signaling In Dendritic Cells, Rodolfo Thome, Jason N. Moore, Elisabeth R. Mari, Javad Rasouli

Department of Neurology Faculty Papers

Peripheral tolerance to autoantigens is induced via suppression of self-reactive lymphocytes, stimulation of tolerogenic dendritic cells (DCs) and regulatory T (Treg) cells. Interleukin (IL)-27 induces tolerogenic DCs and Treg cells; however, it is not known whether IL-27 is important for tolerance induction. We immunized wild-type (WT) and IL-27 receptor (WSX-1) knockout mice with MOG_35-55 for induction of experimental autoimmune encephalomyelitis and intravenously (i.v.) injected them with MOG_35-55 after onset of disease to induce i.v. tolerance. i.v. administration of MOG^35-55 reduced disease severity in WT mice, but was ineffective in Wsx^-/- mice. IL-27 signaling in DCs was …
