5-Hydroxymethylcytosine Localizes To Enhancer Elements And Is Associated With Survival In Glioblastoma Patients, Kevin C. Johnson, E. Andres Houseman, Jessica E. King, Katharine M. Von Herrmann, Camilo E. Fadu, Brock C. Christensen
Dartmouth Scholarship
Glioblastomas exhibit widespread molecular alterations including a highly distorted epigenome. Here, we resolve genome-wide 5-methylcytosine and 5-hydroxymethylcytosine in glioblastoma through parallel processing of DNA with bisulfite and oxidative bisulfite treatments. We apply a statistical algorithm to estimate 5-methylcytosine, 5-hydroxymethylcytosine and unmethylated proportions from methylation array data. We show that 5-hydroxymethylcytosine is depleted in glioblastoma compared with prefrontal cortex tissue. In addition, the genomic localization of 5-hydroxymethylcytosine in glioblastoma is associated with features of dynamic cell-identity regulation such as tissue-specific transcription and super-enhancers. Annotation of 5-hydroxymethylcytosine genomic distribution reveal significant associations with RNA regulatory processes, immune function, stem cell maintenance and …

Children with sickle cell disease experience organ damage, impaired quality of life, and premature mortality. Allogeneic bone marrow transplant from an HLA-matched sibling can halt disease progression but is limited by donor availability. A Blood and Marrow Transplant Clinical Trials Network (BMT CTN) phase 2 trial conducted from 2008 to 2014 enrolled 30 children aged 4 to 19 years; 29 were eligible for evaluation. The primary objective was 1-year event-free survival (EFS) after HLA allele-matched (at HLA-A, -B, -C, and -DRB1 loci) unrelated donor transplant. The conditioning regimen included alemtuzumab, fludarabine, and melphalan. Graft-versus-host disease (GVHD) prophylaxis included calcineurin inhibitor, …

Michael Wilkerson, Melissa Harrell, Andrew Obala, Benjamin Amick
Collected Faculty Scholarship
Background
Most patients with malaria seek treatment first in retail drug shops. Myriad studies have examined retailer behaviours and characteristics to understand the determinants to these behaviours. Geospatial methods are helpful in discovering if geographic location plays a role in the relationship between determinants and outcomes. This study aimed to discover if spatial autocorrelation exists in the relationship between determinants and retailer behaviours, and to provide specific geographic locations and target behaviours for tailoring future interventions.
Methods
Retailer behaviours and characteristics captured from a survey deployed to medicine retailers in the Webuye Demographic and Health Surveillance Site were analysed using …

BACKGROUND: A new disease class of syndromes, described as linkeropathies, which are derived from defects in the glycosaminoglycan-linker region as well as glycosaminoglycan-side chains of proteoglycans is increasingly being recognized as a cause of human disease. Proteoglycans are an essential component of the extracellular matrix. Defects in the enzymatic process of proteoglycan synthesis broadly occur due to the incorrect addition of side chains. Previously, homozygous missense variants within the B3GAT3 gene encoding beta 1,3 glucuronyltransferase 3(GlcAT-I) responsible for the biosynthesis of glycosaminoglycans have been described in 7 individuals.

Introduction: Every new HIV infection is preventable and every HIV-related death is avoidable. As many jurisdictions around the world endeavour to end HIV as an epidemic, missed HIV prevention and treatment opportunities must be regarded as public health emergencies, and efforts to quickly fill gaps in service provision for all people living with and vulnerable to HIV infection must be prioritized.
Discussion: We present a novel, comprehensive, primary and secondary HIV prevention continuum model for the United States as a conceptual framework to identify key steps in reducing HIV incidence and improving health outcomes among those vulnerable to, as well …

Oxytocin (OT) has become a focus in investigations of autism spectrum disorder (ASD). The social deficits that characterize ASD may relate to reduced connectivity between brain sites on the mesolimbic reward pathway (nucleus accumbens; amygdala) that receive OT projections and contribute to social motivation, and cortical sites involved in social perception. Using functional magnetic resonance imaging and a randomized, double blind, placebo-controlled crossover design, we show that OT administration in ASD increases activity in brain regions important for perceiving social-emotional information. Further, OT enhances connectivity between nodes of the brain's reward and socioemotional processing systems, and does so preferentially for …

Background: Deep brain stimulation (DBS) has been shown to be effective for parkinsonian symptoms poorly responsive to medications. DBS is typically well-tolerated, as are the maintenance battery changes. Here we describe an adverse event during a battery replacement procedure that caused rapid onset of severe depression.
Case Presentation: The patient is a 58-year-old woman who was in a serious motor vehicle accident and sustained a concussion with loss of consciousness. Within weeks of the accident she began developing parkinsonian symptoms that progressively worsened over the subsequent 10 years. Responding poorly to medications, she received DBS, which controlled her movement symptoms. …

Photovoice Of Obesity On Murray State University's Campus, Karley Wray, Melissa Godby
Scholars Week
The issue we decided to discuss on campus using Photovoice was obesity. Obesity is becoming a very big topic that we all need to start focusing on. Obesity is defined as having a BMI at or above 30. This is becoming more common with our cultural change. We are becoming more fast food eaters and are not exercising as much as we should. It is even getting worse on college campuses. We all knew of what was called the freshmen 15, but now it is becoming a four year 15. It is becoming more common for college students to become …

Statins, a class of cholesterol-lowering medications that inhibit 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase, are commonly administered to treat atherosclerotic cardiovascular disease. Statin use may expand considerably given its potential for treating an array of cholesterol-independent diseases. However, the lack of conclusive evidence supporting these emerging therapeutic uses of statins brings to the fore a number of unanswered questions including uncertainties regarding patient-to-patient variability in response to statins, the most appropriate statin to be used for the desired effect, and the efficacy of statins in treating cholesterol-independent diseases. In this review, the adverse effects, costs, and drug–drug and drug–food interactions associated with statin …

Photothermal Therapy Improves The Efficacy Of A Mek Inhibitor In Neurofibromatosis Type 1-Associated Malignant Peripheral Nerve Sheath Tumors., Elizabeth E. Sweeney, Rachel A. Burga, Chaoyang Li, Yuan Zhu, Rohan Fernandes
Pediatrics Faculty Publications
Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive tumors with low survival rates and the leading cause of death in neurofibromatosis type 1 (NF1) patients under 40 years old. Surgical resection is the standard of care for MPNSTs, but is often incomplete and can generate loss of function, necessitating the development of novel treatment methods for this patient population. Here, we describe a novel combination therapy comprising MEK inhibition and nanoparticle-based photothermal therapy (PTT) for MPNSTs. MEK inhibitors block activity driven by Ras, an oncogene constitutively activated in NF1-associated MPNSTs, while PTT serves as a minimally invasive method to ablate …

Journal of Patient-Centered Research and Reviews
Congestive heart failure (CHF) is a major cause of morbidity and mortality. Early diagnosis of CHF in patients presenting to the emergency department with undifferentiated dyspnea would allow clinicians to begin appropriate treatment more promptly. Current guidelines recommend B-type natriuretic peptide (BNP) levels for more accurate diagnosis of CHF in dyspneic patients. Although BNP levels are relatively inexpensive, the test is not usually performed at bedside and results may take up to an hour or more. BNP also may have a “gray zone” in which the values can neither confirm nor rule out CHF. BNP has a reported sensitivity of …

Journal of Patient-Centered Research and Reviews
Background: About 20% of patients who develop left ventricular (LV) systolic dysfunction will have improvement in ejection fraction (LVEF) over time. This patient cohort is generally excluded from large sudden death trials and, hence, understudied.
Purpose: To evaluate the predictors of mortality in patients with severe LV systolic dysfunction who have improvement in LVEF during follow-up.
Methods: Patients who had transient LV systolic dysfunction from 2010 to 2014 within the Aurora Health Care system and who had LVEF improve to ≥ 40%, irrespective of implantable cardioverter-defibrillator (ICD) implant, were studied. Predictors of mortality were identified using Cox proportional hazards model. …

Seniors Welcome! Avoiding The Trap Of Age Limits In Health Research, Arshad Jahangir
Journal of Patient-Centered Research and Reviews
The guest editor introduces this specialty issue of the Journal of Patient-Centered Research and Reviews, which focuses on cardiovascular diseases in the elderly. The reality of an aging population has increased the need for better evidence-based medicine in older patients. However, randomized controlled trials frequently exclude such patients, especially those with comorbidities, from study. This practice ignores the fact that physiologic changes to the cardiovascular system caused by the aging process and aging-associated diseases create clinical dilemmas distinct from those in younger patients. Considering the rising costs of health care and growing incidence of cardiovascular disease, research efforts and …

Purpose
Outcomes in patients with atrial fibrillation who develop acute mesenteric ischemia, and the impact of anticoagulation on complications, are not defined.
Methods
Patients admitted with acute mesenteric ischemia in the National Inpatient Sample from 2007, with and without atrial fibrillation, were compared for in-hospital outcomes using multivariate regression, and the impact of prior anticoagulation determined.
Results
Of 48,872 patients with acute mesenteric ischemia, 8,306 had atrial fibrillation, with 680 patients also on anticoagulation. Atrial fibrillation patients were more likely to be older and have hypertension, heart failure, or chronic lung or renal disease. After adjusting for potential confounders, atrial …

Advanced Heart Failure Treatment Options Among The Elderly, German Guzman-Gutierrez, Yang Shi, Matthew Rappelt, Arshad Jahangir, Vinay Thohan
Journal of Patient-Centered Research and Reviews
The aging human population has emerged as a critically important factor in health care, not only due to the unique physiologic and pathologic processes associated with aging but also because of the evolution of medical and surgical therapies that have increased quality and quantity of life. Heart failure is a disease found most commonly among older populations in whom it is associated with high morbidity and mortality. Heart failure disproportionately affects the elderly, and it stands to reason that the most terminal stage, known as advanced heart failure (AHF), is more common among the elderly. Despite limited data, treatment options …

Atrial Fibrillation And Stroke In Elderly Patients, Geetanjali Dang, Imaan Jahangir, Jasbir Sra, A. Jamil Tajik, Arshad Jahangir
Journal of Patient-Centered Research and Reviews
The increasing prevalence of stroke, with an estimated annual cost of $71.5 billion, has made it a major health problem that increases disability and death, particularly in patients with atrial fibrillation. Although advanced age and atrial fibrillation are recognized as strong risk factors for stroke, the basis for this susceptibility are not well defined. Aging or associated diseases are accompanied by changes in rheostatic, humoral, metabolic and hemodynamic factors that may contribute more to stroke predisposition than rhythm abnormality alone. Several thromboembolism-predisposing clinical characteristics and serum biomarkers with prognostic significance have been identified in patients with atrial fibrillation. Although anticoagulation …

Path To Resistance: Risk Factors Associated With Carbapenem-Resistant Pseudomonas Aeruginosa, Kushal Patel, Jessica J.F. Kram, Dennis J. Baumgardner
Journal of Patient-Centered Research and Reviews
Background: An estimated 51,000 health care-associated Pseudomonas aeruginosa infections occur in the United States annually. More than 13% are secondary to non-carbapenem multidrug-resistant strains, which result in 400 yearly deaths. Traditional risk factors for resistance include ICU stay, mechanical ventilation, previous hospitalization and major comorbidities. As microbes evolve, risk factors also may evolve.
Purpose: To determine if traditional and/or new risk factors for P. aeruginosa resistance are valid and predictive of infection with carbapenem-resistant P. aeruginosa.
Methods: We retrospectively studied inpatients and outpatients ≥ 18 years old who presented to an Aurora Health Care facility with a positive P. …
Cost-Effectiveness Of Genomic-Based Warfarin Therapy, John Weissert, Kourosh Ravvaz
Cost-Effectiveness Of Genomic-Based Warfarin Therapy, John Weissert, Kourosh Ravvaz
Journal of Patient-Centered Research and Reviews
Background: With over 40 years of demonstrated clinical efficacy, warfarin remains the world’s most used pharmaceutical to prevent ischemic stroke in patients with atrial fibrillation (AF). However, warfarin has many challenges. Thus, despite known effectiveness, warfarin is a leading cause to drug-induced morbidity and mortality. Over 50 different warfarin therapy protocols, including a number of pharmacogenomic-based (PG) protocols, with as many as 14 independent variables, have been developed to improve safety and efficacy, thereby reducing ischemic strokes and intracranial hemorrhages (ICH).
Purpose: To conduct a preliminary cost-effectiveness study to determine the price point at which using warfarin PG dosing to …

Journal of Patient-Centered Research and Reviews
Background: Liver transplantation is often associated with massive blood loss due to surgical complexity and the hemostatic abnormalities of end-stage liver disease. Blood transfusions have been associated with increased risk of infection, multiorgan dysfunction, graft loss and mortality.
Purpose: To determine for liver transplantation whether correlation exists between preoperative anemia and transfusion requirements, length of stay or incidence of postoperative infection.
Methods: A retrospective review of liver transplantations from Jan. 1, 2012, to June 30, 2015, was conducted. Packed red blood cell (PRBC), fresh frozen plasma (FFP), platelet and cryoprecipitate units were collected preoperatively, intraoperatively and within the first 48 …

Background: Catheter ablation of the cavotricuspid isthmus (CTI) is traditionally performed using fluoroscopy and electroanatomical mapping systems. Zero-fluoroscopy approaches have recently been studied, mostly using the EnSite® mapping system (St. Jude Medical Inc., St. Paul, MN). We studied the feasibility and efficacy of zero-fluoroscopic mapping and ablation of the CTI using the Carto® 3 system (Biosense Webster Inc., South Diamond Bar, CA).
Purpose: To evaluate the efficacy and safety of a zero-fluoroscopic approach to CTI ablation.
Methods: We included 9 patients with typical atrial flutter for whom mapping and ablation of the CTI was done using Carto mapping …

In an aged population, cardiovascular disease is the leading cause of fatality and morbidity. Age-related fibrotic remodeling of the heart contributes to progressive myocardial dysfunction. Cardiac fibroblasts (CF), responsible for the maintenance of extracellular matrix and fibrosis process, play an important role in cardiac health and disease. CFs influence myocardial function by their chemical, electrical and mechanical interactions with cardiomyocytes through extracellular matrix deposition or secretion of cytokines and growth factors. These, in turn, are modulated by ion channels, macromolecular pores in the plasma membrane that allow selective ionic fluxes of major ions like K+, Ca2+, …

Background: Preoperative risk assessments of individuals who undergo major noncardiac surgery have focused on ischemic heart disease. Information on how to assess the noncardiac surgical risks for patients with depressed cardiac function, as seen in heart failure, is sparse. Echocardiography is routinely performed in patients with depressed cardiac function and is an accepted standard cardiac assessment. Transthoracic echocardiography (TTE) provides strong independent prognostic implications in a wide range of cardiovascular conditions.
Purpose: To identify the echocardiographic parameters associated with outcomes among patients undergoing major noncardiac surgery.
Methods: A retrospective single-institution investigation identified 1,770 patients who underwent one or more major …

Background: Anthracycline and trastuzumab are common breast cancer treatments. While improving survival, they elevate risk of congestive heart failure. The incidence of cardiotoxicity (CTx) with these therapies varies in the literature from 10% to 59%, higher than those reported in clinical trials (4%–10%) that excluded patients with preexisting cardiovascular comorbidities. Studies have failed to establish consensus on the risk factors for CTx associated with these therapies.
Purpose: We aim to determine the incidence and risk factors of CTx in breast cancer patients treated with anthracycline and/or trastuzumab at Aurora Health Care.
Methods: A retrospective review of patients with breast cancer …
