METHODS: Women with breast cancer (n = 327) completed the Menopausal Symptoms Scale, which evaluated the occurrence, severity, and distress of 46 common menopausal-related symptoms. Regression analyses were used to evaluate between-group differences in the seven symptoms …

A Test Of Multisession Automatic Action Tendency Retraining To Reduce Alcohol Consumption Among Young Adults In The Context Of A Human Laboratory Paradigm., Robert F Leeman, Christine Nogueira, Reinout W Wiers, Janna Cousijn, Kelly Serafini, Kelly S Demartini, John A Bargh, Stephanie S O'Malley

Articles, Abstracts, and Reports

BACKGROUND: Young adult heavy drinking is an important public health concern. Current interventions have efficacy but with only modest effects, and thus, novel interventions are needed. In prior studies, heavy drinkers, including young adults, have demonstrated stronger automatically triggered approach tendencies to alcohol-related stimuli than lighter drinkers. Automatic action tendency retraining has been developed to correct this tendency and consequently reduce alcohol consumption. This study is the first to test multiple iterations of automatic action tendency retraining, followed by laboratory alcohol self-administration.

METHODS: A total of 72 nontreatment-seeking, heavy drinking young adults ages 21 to 25 were randomized to automatic …

Opportunities And Obstacles For Deep Learning In Biology And Medicine, Travers Ching, S Joshua Swamidass, Et Al

2010-2019 OA Pubs

Deep learning describes a class of machine learning algorithms that are capable of combining raw inputs into layers of intermediate features. These algorithms have recently shown impressive results across a variety of domains. Biology and medicine are data-rich disciplines, but the data are complex and often ill-understood. Hence, deep learning techniques may be particularly well suited to solve problems of these fields. We examine applications of deep learning to a variety of biomedical problems-patient classification, fundamental biological processes and treatment of patients-and discuss whether deep learning will be able to transform these tasks or if the biomedical sphere poses unique …

High Sodium Continuous Veno-Venous Hemodialysis With Regional Citrate Anticoagulation And Online Dialysate Generation In Patients With Acute Liver Failure And Cerebral Edema, Tamim Hamdi, Lenar Yessayan, Jerry Yee, Balazs Szamosfalvi

Nephrology Articles

INTRODUCTION: Acute liver failure is associated with a high mortality rate. Induction of plasma hypertonicity with mannitol or hypertonic saline remains the cornerstone in the management of resultant cerebral edema. Significant disadvantages of this approach include poor or unpredictable control of serum sodium concentration and volume expansion, among others.

METHODS: We used high sodium continuous veno-venous hemodialysis with regional citrate anticoagulation and online dialysate generation to accurately control the serum sodium in eleven patients with acute liver failure, renal failure, and cerebral edema. We used a Fresenius 2008 K/K2 machine in hemodialysis mode to deliver a blood flow of 60 …

Early Relapse After Autologous Hematopoietic Cell Transplantation Remains A Poor Prognostic Factor In Multiple Myeloma But Outcomes Have Improved Over Time, Shaji K. Kumar, Angela Dispenzieri, Raphael Fraser, Fei Mingwei, Gorgun Akpek, Robert Cornell, Mohamed Kharfan-Dabaja, Cesar Freytes, Shahrukh Hashmi, Gerhard C.

Duration of initial disease response remains a strong prognostic factor in multiple myeloma (MM) particularly for upfront autologous hematopoietic cell transplant (AHCT) recipients. We hypothesized that new drug classes and combinations employed prior to AHCT as well as after post-AHCT relapse may have changed the natural history of MM in this population. We analyzed the Center for International Blood and Marrow Transplant Research database to track overall survival (OS) of MM patients receiving single AHCT within 12 months after diagnosis (N=3256) and relapsing early post-AHCT (< 24 months), and to identify factors predicting for early vs late relapses (24−48 months post-AHCT). Over three periods (2001–2004, 2005–2008, 2009–2013), patient characteristics were balanced except for lower proportion of Stage III, higher likelihood of one induction therapy with novel triplets and higher rates of planned post-AHCT maintenance over time. The proportion of patients relapsing early was stable over time at 35–38%. Factors reducing risk of early relapse included lower stage, chemosensitivity, transplant after 2008 and post-AHCT maintenance. Shorter post-relapse OS was associated with early relapse, IgA MM, Karnofsky < 90, stage III, > 1 line of induction and lack of maintenance. Post-AHCT early relapse remains …

Short Term Development And Fate Of Mge-Like Neural Progenitor Cells In Jaundiced And Non-Jaundiced Rat Brain., Fu-Chen Yang, Julia Draper, Peter G Smith, Jay L. Vivian, Steven Shapiro, John A. Stanford

Manuscripts, Articles, Book Chapters and Other Papers

Neonatal hyperbilirubinemia targets specific brain regions and can lead to kernicterus. One of the most debilitating symptoms of kernicterus is dystonia, which results from bilirubin toxicity to the globus pallidus (GP). Stem cell transplantation into the GP to replace lost neurons and restore basal ganglia circuits function is a potential therapeutic strategy to treat dystonia in kernicterus. In this study we transplanted human medial ganglionic eminence (MGE)-like neural progenitor cells (NPCs) that we differentiated into a primarily gamma-aminobutyric acid (GABA)ergic phenotype, into the GP of non-immunosuppressed jaundiced (jj) and non-jaundiced (Nj) rats. We assessed the survival and development of graft …

Prenatal Exposure To Methadone Or Buprenorphine: Early Childhood Developmental Outcomes., Karol Kaltenbach, Kevin E O'Grady, Sarah H. Heil, Amy L. Salisbury, Mara G. Coyle, Gabriele Fischer, Peter R. Martin, Susan Stine, Hendrée E. Jones

Department of Pediatrics Faculty Papers

BACKGROUND: Methadone and buprenorphine are recommended to treat opioid use disorders during pregnancy. However, the literature on the relationship between longer-term effects of prenatal exposure to these medications and childhood development is both spare and inconsistent.

METHODS: Participants were 96 children and their mothers who participated in MOTHER, a randomized controlled trial of opioid-agonist pharmacotherapy during pregnancy. The present study examined child growth parameters, cognition, language abilities, sensory processing, and temperament from 0 to 36 months of the child's life. Maternal perceptions of parenting stress, home environment, and addiction severity were also examined.

RESULTS: Tests of mean differences between children …

Differences In Work Environment For Staff As An Explanation For Variation In Central Line Bundle Compliance In Intensive Care Units., Yuna S.H. Lee, Patricia W. Stone, Monika Pogorzelska-Maziarz, Ingrid M. Nembhard

College of Nursing Faculty Papers & Presentations

BACKGROUND: Central line-associated bloodstream infections (CLABSIs) are a common and costly quality problem, and their prevention is a national priority. A decade ago, researchers identified an evidence-based bundle of practices that reduce CLABSIs. Compliance with this bundle remains low in many hospitals.

PURPOSE: The aim of this study was to assess whether differences in core aspects of work environments-workload, quality of relationships, and prioritization of quality-are associated with variation in maximal CLABSI bundle compliance, that is, compliance 95%-100% of the time in intensive care units (ICUs).

METHODOLOGY/APPROACH: A cross-sectional study of hospital medical-surgical ICUs in the United States was done. …

Building Capacity For Evidence-Based Public Health: Reconciling The Pulls Of Practice And The Push Of Research, Ross C Brownson, Jonathan E Fielding, Lawrence W Green

Open Access Publications

Timely implementation of principles of evidence-based public health (EBPH) is critical for bridging the gap between discovery of new knowledge and its application. Public health organizations need sufficient capacity (the availability of resources, structures, and workforce to plan, deliver, and evaluate the preventive dose of an evidence-based intervention) to move science to practice. We review principles of EBPH, the importance of capacity building to advance evidence-based approaches, promising approaches for capacity building, and future areas for research and practice. Although there is general agreement among practitioners and scientists on the importance of EBPH, there is less clarity on the definition …

Edoxaban Plus Aspirin Vs Dual Antiplatelet Therapy In Endovascular Treatment Of Patients With Peripheral Artery Disease: Results Of The Epad Trial., Frans Moll, Iris Baumgartner, Michael Jaff, Chuke Nwachuku, Marco Tangelder, Gary Ansel, George Adams, Thomas Zeller, John Rundback, Michael Grosso, Min Lin, Michele F Mercur, Erich Minar, Epad Investigators

Pharmacy Articles

PURPOSE: To report a randomized study that investigated the safety (risk of major bleeds) and potential efficacy of edoxaban, an oral anticoagulant that targets the major components of arterial thrombi, to prevent loss of patency following endovascular treatment (EVT).

METHODS: Between February 2012 and June 2014, 203 patients who underwent femoropopliteal EVT were randomized to receive aspirin plus edoxaban or aspirin plus clopidogrel for 3 months in the Edoxaban in Peripheral Arterial Disease (ePAD) study ( ClinicalTrials.gov identifier NCT01802775). Randomization assigned 101 patients (mean age 68.0±10.4 years; 67 men) to the edoxaban group and 102 patients (mean age 66.7±8.6 years; …

Validation Of An Icd Code For Accurately Identifying Emergency Department Patients Who Suffer An Out-Of-Hospital Cardiac Arrest., Shelby K. Shelton, Steve B. Chukwulebe, David F. Gaieski, Benjamin S. Abella, Brendan G. Carr, Sarah M. Perman

Department of Emergency Medicine Faculty Papers

AIM: International classification of disease (ICD-9) code 427.5 (cardiac arrest) is utilized to identify cohorts of patients who suffer out-of-hospital cardiac arrest (OHCA), though the use of ICD codes for this purpose has never been formally validated. We sought to validate the utility of ICD-9 code 427.5 by identifying patients admitted from the emergency department (ED) after OHCA.

METHODS: Adult visits to a single ED between January 2007 and July 2012 were retrospectively examined and a keyword search of the electronic medical record (EMR) was used to identify patients. Cardiac arrest was confirmed; and ICD-9 information and location of return …

New Pulmonary Valvuloplasty Technique By Use Of An Hourglass-Shaped Balloon In 3 Adults With Severe Pulmonary Valve Stenosis, Teoman Kilic, Tayfun Sahin, Kurtulus Karauzum, Ertan Ural, Wesley R Pedersen

The Texas Heart Institute Journal

Percutaneous balloon pulmonary valvuloplasty is the preferred therapy for pulmonary valve stenosis. However, the designs of the cylindrical balloons historically used for valvuloplasty have limitations, especially in patients who have large pulmonary annular diameters. The hourglass-shaped V8 Aortic Valvuloplasty Balloon may prove to be an effective alternative. The balloon has 2 large bulbous segments that are separated by a narrowed waist. The geometric shape is maintained throughout inflation, improving fixation and enabling broader leaflet opening. We present our first experience with the V8 balloon in 3 adults who had severe, symptomatic pulmonary valve stenosis. In addition to describing their cases, …

Cardiac Magnetic Resonance To Evaluate Percutaneous Pulmonary Valve Implantation In Children And Young Adults, Cesar Gonzalez De Alba, Fernando Molina Berganza, John Brownlee, Muhammad Khan, Dilachew Adebo

The Texas Heart Institute Journal

Experience with cardiac magnetic resonance to evaluate coronary arteries in children and young adult patients is limited. Because noninvasive imaging has advantages over coronary angiography, we compared the effectiveness of these techniques in patients who were being considered for percutaneous pulmonary valve implantation.

We retrospectively reviewed the cases of 26 patients (mean age, 12.53 ± 4.85 yr; range, 5–25 yr), all of whom had previous right ventricular-to-pulmonary artery homografts. We studied T2-prepared whole-heart images for coronary anatomy, velocity-encoded cine images for ventricular morphology, and function- and time-resolved magnetic resonance angiographic findings. Cardiac catheterization studies included coronary angiography, balloon compression testing, …

Changes In Coronary Plaque Volume: Comparison Of Serial Measurements On Intravascular Ultrasound And Coronary Computed Tomographic Angiography, Rine Nakanishi, Anas Alani, Suguru Matsumoto, Dong Li, Michael Fahmy, Jeby Abraham, Christopher Dailing, Alexander Broersen, Pieter H Kitslaar, Khurram Nasir, James K Min, Matthew J Budoff

The Texas Heart Institute Journal

Serial measurements of coronary plaque volume have been used to evaluate drug efficacy in atherosclerotic progression. However, the usefulness of computed tomography for this purpose is unknown. We investigated whether the change in total plaque volume on coronary computed tomographic angiography is associated with the change in segment plaque volume on intravascular ultrasound. We prospectively enrolled 11 consecutive patients (mean age, 56.3 ± 5 yr; 6 men) who were to undergo serial invasive coronary angiographic examinations with use of grayscale intravascular ultrasound and coronary computed tomography, performedvolume, nor between normalized coronary plaque volume. However, in the per-patient analysis, there were …

Murmur Associated With Diastolic Paradoxical Jet Flow In A 43-Year-Old Man With Hypertrophic Cardiomyopathy, Michiyo Yamano, Tatsuya Kawasaki, Hirokazu Shiraishi, Tadaaki Kamitani, Takatomo Shima, Takashi Nakamura, Satoaki Matoba

The Texas Heart Institute Journal

A diastolic paradoxical jet flow, often seen in patients with hypertrophic cardiomyopathy, is a unique flow from the apex toward the base of the left ventricle during isovolumic relaxation. To date, this phenomenon appears to have been noninvasively detected only on echocardiograms. We report the case of a 43-year-old man with hypertrophic cardiomyopathy and a diastolic paradoxical jet flow, in whom cardiac auscultation revealed a soft S4, a systolic ejection murmur, and a low-pitched early diastolic murmur immediately after S2 at the apex. On comparing his echocardiographic findings with those on phonocardiograms and apexcardiograms, we confirmed that the unusual murmur …

Comorbidities In Aging Patients With Sickle Cell Disease., Samir K. Ballas

Cardeza Foundation for Hematologic Research

Sickle cell disease (SCD) in general and sickle cell anemia in particular is a highly complex disorder both at the molecular and clinical levels. Although the molecular lesion is a single-point mutation, the sickle gene is pleiotropic in nature causing multiple phenotypic expressions that constitute the various complications of the disease. Moreover, despite the fact that SCD is a chronic malady, its manifestations are both acute and chronic. The former include, among other things, the recurrent vaso-occlusive crises (its hallmark) and acute chest syndrome. The chronic complications include most commonly avascular necrosis and leg ulcers. Currently, survival of patients with …

Scalable Open Science Approach For Mutation Calling Of Tumor Exomes Using Multiple Genomic Pipelines, Kyle Ellrott, Matthew H Bailey, Gordon Saksena, Kyle R Covington, Cyriac Kandoth, Chip Stewart, Julian Hess, Singer Ma, Kami E Chiotti, Michael Mclellan, Heidi J Sofia, Carolyn Hutter, Gad Getz, David Wheeler, Li Ding, Mc3 Working Group, The Cancer Genome Atlas Research Network

Open Access Publications

The Cancer Genome Atlas (TCGA) cancer genomics dataset includes over 10,000 tumor-normal exome pairs across 33 different cancer types, in total >400 TB of raw data files requiring analysis. Here we describe the Multi-Center Mutation Calling in Multiple Cancers project, our effort to generate a comprehensive encyclopedia of somatic mutation calls for the TCGA data to enable robust cross-tumor-type analyses. Our approach accounts for variance and batch effects introduced by the rapid advancement of DNA extraction, hybridization-capture, sequencing, and analysis methods over time. We present best practices for applying an ensemble of seven mutation-calling algorithms with scoring and artifact filtering. …

Sickle Cell Disease: Classification Of Clinical Complications And Approaches To Preventive And Therapeutic Management., Samir K. Ballas

Department of Medicine Faculty Papers

Sickle cell disease (SCD) is an inherited disorder of hemoglobin structure that has no established cure in adult patients. Cure has been achieved in selected children with sickle cell anemia (SCA) using allogeneic bone marrow transplantation or cord blood transplantation. SCD is essentially a triumvirate of (1) pain syndromes, (2) anemia and its sequelae and (3) organ failure, including infection. Pain, however, is the hallmark of SCD and dominates its clinical picture throughout the life of the patients. The prevalence of these complications varies with age from infancy through adult life. However, pain, infections and anemia requiring blood transfusion occur …

Blood Rheological Abnormalities In Sickle Cell Anemia., Philippe Connes, Céline Renoux, Marc Romana, Manouk Abkarian, Philippe Joly, Cyril Martin, Marie-Dominique Hardy-Dessources, Samir K. Ballas

Department of Medicine Faculty Papers

This review focuses on the contribution of abnormal blood rheology in the pathophysiology of sickle cell anemia (SCA). SCA is characterized by a reduction of red blood cell (RBC) deformability but this reduction is very heterogeneous among patients. Recent works have shown that patients with the lowest RBC deformability (measured by ektacytometry) have enhanced hemolysis and would be more prone to develop several complications such as priapism, leg ulcers and glomerulopathy. In contrast, patients with the highest deformability, and not under hydroxyurea therapy, seem to develop more frequently vaso-occlusive like events. Although less studied, RBC aggregation properties are very different …

Transcriptional Regulatory Networks Underlying Gene Expression Changes In Huntington's Disease., Seth A Ament, Jocelynn R Pearl, Jeffrey P Cantle, Robert M Bragg, Peter J Skene, Sydney R Coffey, Dani E Bergey, Vanessa C Wheeler, Marcy E Macdonald, Nitin S Baliga, Jim Rosinski, Leroy E Hood, Jeffrey B Carroll, Nathan D Price

Articles, Abstracts, and Reports

Transcriptional changes occur presymptomatically and throughout Huntington's disease (HD), motivating the study of transcriptional regulatory networks (TRNs) in HD We reconstructed a genome-scale model for the target genes of 718 transcription factors (TFs) in the mouse striatum by integrating a model of genomic binding sites with transcriptome profiling of striatal tissue from HD mouse models. We identified 48 differentially expressed TF-target gene modules associated with age- and CAG repeat length-dependent gene expression changes in

Utilization Of Prevention Of Mother-To-Child Transmission (Pmtct) Services Among Pregnant Women In Hiv Care In Uganda: A 24-Month Cohort Of Women From Pre-Conception To Post-Delivery., Rhoda K Wanyenze, Kathy Goggin, Sarah Finocchario-Kessler, Jolly Beyeza-Kashesya, Deborah Mindry, Josephine Birungi, Mahlet Woldetsadik, Glenn J Wagner

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVE: We assessed the uptake of prevention of mother-to-child transmission (PMTCT) services in a cohort of HIV infected women in care at The AIDS Support Organization Jinja and Kampala in Uganda, who were trying to conceive, over a period of 24 months, to inform the strengthening of PMTCT service access for women in care.

RESULTS: Of the 299 women 127 (42.5%) reported at least one pregnancy within 24 months; 61 women (48.0%) delivered a live child. Of the 55 who had a live birth at the first pregnancy, 54 (98.2%) used antenatal care (ANC) starting at 15.5 weeks of gestation …

A Model-Based Approach For Estimation Of Changes In Lumbar Segmental Kinematics Associated With Alterations In Trunk Muscle Forces, Iman Shojaei, Navid Arjmand, Judith R. Meakin, Babak Bazrgari

Biomedical Engineering Faculty Publications

The kinematics information from imaging, if combined with optimization-based biomechanical models, may provide a unique platform for personalized assessment of trunk muscle forces (TMFs). Such a method, however, is feasible only if differences in lumbar spine kinematics due to differences in TMFs can be captured by the current imaging techniques. A finite element model of the spine within an optimization procedure was used to estimate segmental kinematics of lumbar spine associated with five different sets of TMFs. Each set of TMFs was associated with a hypothetical trunk neuromuscular strategy that optimized one aspect of lower back biomechanics. For each set …

Walking Speed Differentially Alters Spinal Loads In Persons With Traumatic Lower Limb Amputation, Brad D. Hendershot, Iman Shojaei, Julian C. Acasio, Christopher L. Dearth, Babak Bazrgari

Biomedical Engineering Faculty Publications

Persons with lower limb amputation (LLA) perceive altered motions of the trunk/pelvis during activities of daily living as contributing factors for low back pain. When walking (at a singular speed), larger trunk motions among persons with vs. without LLA are associated with larger spinal loads; however, modulating walking speed is necessary in daily life and thus understanding the influences of walking speed on spinal loads in persons with LLA is of particular interest here. Three-dimensional trunk-pelvic kinematics, collected during level-ground walking at self-selected (SSW) and two controlled speeds (~1.0 and ~1.4 m/s), were obtained for seventy-eight participants: 26 with transfemoral …

Mechanical Demands On The Lower Back In Patients With Non-Chronic Low Back Pain During A Symmetric Lowering And Lifting Task, Iman Shojaei, Elizabeth G. Salt, Quenten L. Hooker, Babak Bazrgari

Biomedical Engineering Faculty Publications

There is limited information in the literature related to the lower back loading in patients with LBP, particularly those with non-chronic LBP. Toward addressing such a research gap, a case-control study was conducted to explore the differences in lower back mechanical loads between a group of females (n=19) with non-chronic, non-specific LBP and a group of asymptomatic females (n=19). The differences in lower back mechanical loads were determined when participants completed one symmetric lowering and lifting of a 4.5 kg load at their preferred cadence. The axial, shearing, and moment components of task demand at the time of peak moment …

Profiling Prostate Cancer Therapeutic Resistance, Cameron A. Wade, Natasha Kyprianou

Urology Faculty Publications

The major challenge in the treatment of patients with advanced lethal prostate cancer is therapeutic resistance to androgen-deprivation therapy (ADT) and chemotherapy. Overriding this resistance requires understanding of the driving mechanisms of the tumor microenvironment, not just the androgen receptor (AR)-signaling cascade, that facilitate therapeutic resistance in order to identify new drug targets. The tumor microenvironment enables key signaling pathways promoting cancer cell survival and invasion via resistance to anoikis. In particular, the process of epithelial-mesenchymal-transition (EMT), directed by transforming growth factor-β (TGF-β), confers stem cell properties and acquisition of a migratory and invasive phenotype via resistance to anoikis. Our …

An Individualized, Perception-Based Protocol To Investigate Human Physiological Responses To Cooling, Crystal L. Coolbaugh, Emily C. Bush, Elizabeth S. Galenti, E Brian Welch, Theodore F. Towse

Peer Reviewed Articles

Cold exposure, a known stimulant of the thermogenic effects of brown adipose tissue (BAT), is the most widely used method to study BAT physiology in adult humans. Recently, individualized cooling has been recommended to standardize the physiological cold stress applied across participants, but critical experimental details remain unclear. The purpose of this work was to develop a detailed methodology for an individualized, perception-based protocol to investigate human physiological responses to cooling. Participants were wrapped in two water-circulating blankets and fitted with skin temperature probes to estimate BAT activity and peripheral vasoconstriction. We created a thermoesthesia graphical user interface (tGUI) to …
