Time Of Year Affects Surgical Outcome Of Pediatric Congenital Heart Disease, Krystin Sinclair 2016 Bryant University

Time Of Year Affects Surgical Outcome Of Pediatric Congenital Heart Disease, Krystin Sinclair

Honors Projects in Science and Technology

Approximately 35,000 children are born in the US each year with Congenital Heart Disease (CHD). Surgical timing for many of these conditions is elective, and the distribution of surgical cases, therefore, varies with time of year. The hypothesis of this project is that time of the year for surgery is associated with mortality, length of hospital stay (LOS), and total hospital costs. A retrospective, cohort study was performed, using the Pediatric Health Information Systems (PHIS) Database to investigate these relationships.

OBJECTIVE: To define glomerular filtration rate (GFR) decline, hypertension (HTN), and proteinuria in subjects with autosomal recessive polycystic kidney disease (ARPKD) and compare with 2 congenital kidney disease control groups in the Chronic Kidney Disease in Children cohort.

STUDY DESIGN: GFR decline (iohexol clearance), rates of HTN (ambulatory/casual blood pressures), antihypertensive medication usage, left ventricular hypertrophy, and proteinuria were analyzed in subjects with ARPKD (n = 22) and 2 control groups: aplastic/hypoplastic/dysplastic disorders (n = 44) and obstructive uropathies (n = 44). Differences between study groups were examined with the Wilcoxon rank sum test.

RESULTS: Annualized GFR change in subjects ...

BACKGROUND AND OBJECTIVES: Propranolol is first-line therapy for problematic infantile hemangiomas (IHs). Rebound growth after propranolol discontinuation is noted in 19% to 25% of patients. Predictive factors for rebound are not completely understood and may alter the management approach. The goal of the study was to describe a cohort of patients with IHs treated with propranolol and to identify predictors for rebound growth.

METHODS: A multicenter retrospective cohort study was conducted in patients with IHs treated with propranolol. Patient demographic characteristics, IH characteristics, and specifics of propranolol therapy were obtained. Episodes of rebound growth were recorded. Patients' responses to propranolol ...


Injury Risk Assessment Of The Femur In Children With Osteogenesis Imperfecta, Jessica Marie Fritz 2016 Marquette University

Injury Risk Assessment Of The Femur In Children With Osteogenesis Imperfecta, Jessica Marie Fritz

Dissertations (2009 -)

Osteogenesis imperfecta (OI) is a genetic disorder characterized by increased bone fragility and decreased bone mass, which leads to high rates of bone fracture. OI has a prevalence of 1/5,000 to 1/10,000 in the United States. About 90% of persons with OI have a genetic mutation in the coding for collagen type I, which is the major protein of connective tissues, including bone. While its prevalence classifies it as a rare disease, it is the most common disorder of bone etiology. Until recently, little was known about the mechanics and materials of OI bone or their ...

Manuscripts, Articles, Book Chapters and Other Papers

Inherited renal disease is a leading cause of morbidity and mortality in pediatric nephrology. High throughput advancements in genomics have led to greater understanding of the biologic underpinnings of these diseases. However, the underlying genetic changes explain only part of the molecular biology that contributes to disease manifestation and progression. Other omics technologies will provide a more complete picture of these cellular processes. This review discusses these omics technologies in the context of pediatric renal disease.


Dnah6 And Its Interactions With Pcd Genes In Heterotaxy And Primary Ciliary Dyskinesia, You Li, Hisato Yagi, Gregory M. Hendricks, Gregory J. Pazour, Cecilia W. Lo 2016 University of Pittsburgh

Dnah6 And Its Interactions With Pcd Genes In Heterotaxy And Primary Ciliary Dyskinesia, You Li, Hisato Yagi, Gregory M. Hendricks, Gregory J. Pazour, Cecilia W. Lo

Open Access Articles

Heterotaxy, a birth defect involving left-right patterning defects, and primary ciliary dyskinesia (PCD), a sinopulmonary disease with dyskinetic/immotile cilia in the airway are seemingly disparate diseases. However, they have an overlapping genetic etiology involving mutations in cilia genes, a reflection of the common requirement for motile cilia in left-right patterning and airway clearance. While PCD is a monogenic recessive disorder, heterotaxy has a more complex, largely non-monogenic etiology. In this study, we show mutations in the novel dynein gene DNAH6 can cause heterotaxy and ciliary dysfunction similar to PCD. We provide the first evidence that trans-heterozygous interactions between DNAH6 ...

Background: Neonatal death rate in the United States is 4/1,000 live births; infant death rate is 6/1,000. Group B Streptococcus (GBS) may be transmitted from a colonized mother (rates vary from 15% to 35%) to the newborn during a vaginal delivery, and may contribute to neonatal death.

Purpose: To explore the geographic distribution and associated risk factors for maternal GBS colonization and infant death prior to discharge in eastern Wisconsin births.

Methods: Retrospective study of institutional data from PeriData.net, a comprehensive birth registry, utilizing data from 2007 through 2013 at all Aurora medical centers. Categorical ...


Maternal Anxiety Associated With Newborn Hearing Screening, Stephen J. Tueller, Karl R. White 2016 RTI International

Maternal Anxiety Associated With Newborn Hearing Screening, Stephen J. Tueller, Karl R. White

Journal of Early Hearing Detection and Intervention

The purpose of this study was to determine if newborn hearing screening increases maternal anxiety. Mothers whose infants were screened for hearing were asked how worried they were prior to hospital discharge and again six weeks later. They were also asked if they were more concerned about their baby’s hearing than they were about other aspects of the infant’s health and behavior.

Results showed that mothers worried as much or more about many other aspects of their infants’ health and behavior as about hearing. Mothers whose infants had a false positive screening result were initially more worried about ...

Canine Rd3 Mutation Establishes Rod-Cone Dysplasia Type 2 (Rcd2) As Ortholog Of Human And Murine Rd3, Anna V. Kukekova, Orly Goldstein, Jennifer L. Johnson, Malcolm A. Richardson, Susan E. Pearce-Kelling, Anand Swaroop, James S. Friedman, Gustavo D. Aguirre, Gregory M. Acland

Gustavo D. Aguirre, VMD, PhD

Rod-cone dysplasia type 2 (rcd2) is an autosomal recessive disorder that segregates in collie dogs. Linkage disequilibrium and meiotic linkage mapping were combined to take advantage of population structure within this breed and to fine map rcd2 to a 230-kb candidate region that included the gene C1orf36 responsible for human and murine rd3, and within which all affected dogs were homozygous for one haplotype. In one of three identified canine retinal RD3 splice variants, an insertion was found that cosegregates with rcd2 and is predicted to alter the last 61 codons of the normal open reading frame and further extend ...

Col9a2 And Col9a3 Mutations In Canine Autosomal Recessive Oculoskeletal Dysplasia, Orly Goldstein, Richard Guyon, Anna Kukekova, Tatyana N. Kuznetsova, Susan E. Pearce-Kelling, Jennifer Johnson, Gustavo D. Aguirre, Gregory M. Acland

Gustavo D. Aguirre, VMD, PhD

Oculoskeletal dysplasia segregates as an autosomal recessive trait in the Labrador retriever and Samoyed canine breeds, in which the causative loci have been termed drd1 and drd2, respectively. Affected dogs exhibit short-limbed dwarfism and severe ocular defects. The disease phenotype resembles human hereditary arthro-ophthalmopathies such as Stickler and Marshall syndromes, although these disorders are usually dominant. Linkage studies mapped drd1 to canine chromosome 24 and drd2 to canine chromosome 15. Positional candidate gene analysis then led to the identification of a 1-base insertional mutation in exon 1 of COL9A3 that cosegregates with drd1 and a 1,267-bp deletion mutation in ...

Canine And Human Visual Cortex Intact And Responsive Despite Early Retinal Blindness From Rpe65 Mutation, Geoffrey K. Aguirre, András M. Komáromy, Artur V. Cideciyan, David H. Brainard, Tomas S. Aleman, Alejandro J. Roman, Brian B. Avants, James C. Gee, Marc Korczykowski, William W. Hauswirth, Gregory M. Acland, Gustavo D. Aguirre, Samuel G. Jacobson

Gustavo D. Aguirre, VMD, PhD

Background RPE65 is an essential molecule in the retinoid-visual cycle, and RPE65 gene mutations cause the congenital human blindness known as Leber congenital amaurosis (LCA). Somatic gene therapy delivered to the retina of blind dogs with an RPE65 mutation dramatically restores retinal physiology and has sparked international interest in human treatment trials for this incurable disease. An unanswered question is how the visual cortex responds after prolonged sensory deprivation from retinal dysfunction. We therefore studied the cortex of RPE65-mutant dogs before and after retinal gene therapy. Then, we inquired whether there is visual pathway integrity and responsivity in adult humans ...


Cloning Of Canine Galactokinase (Galk1) And Evaluation As A Candidate Gene For Hereditary Cataracts In Labrador Retrievers, Duska J. Sidjanin, John L. McElwee, Brian Miller, Gustavo D. Aguirre 2016 University of Pennsylvania

Cloning Of Canine Galactokinase (Galk1) And Evaluation As A Candidate Gene For Hereditary Cataracts In Labrador Retrievers, Duska J. Sidjanin, John L. Mcelwee, Brian Miller, Gustavo D. Aguirre

Gustavo D. Aguirre, VMD, PhD

We identified a pedigree of Labrador retrievers (LR) that develop hereditary cataracts between 6 and 18 months of age. In humans, galactokinase deficiency is an autosomal recessive disorder characterized by juvenile onset of cataracts.1 In order to evaluate GALK1 as a candidate gene, we cloned and sequenced the canine GALK1 gene and tested a single nucleotide polymorphism (SNP) in the gene for segregation with cataracts in the LR pedigree.

Canine Multifocal Retinopathy In The Australian Shepherd: A Case Report, Ingo Hoffmann, Karina E. Guziewicz, Barbara Zangerl, Gustavo D. Aguirre, Christian Y. Mardin

Gustavo D. Aguirre, VMD, PhD

A 1-year-old Australian Shepherd (AS) was presented for a routine hereditary eye examination. During the examination multiple raised, brown to orange lesions were noted in the fundus, which could not be attributed to a known retinal disease in this breed. As they clinically most closely resembled canine multifocal retinopathy (cmr) and no indication of an acquired condition was found, genetic tests for BEST1 gene mutations were performed. These showed the dog to be homozygous for the cmr1 (C73T/R25X) gene defect. Furthermore, ultrasound (US), electroretinography (ERG), and optical coherence tomography were performed, confirming changes typical for cmr. Subsequently, the AS ...

The Heli-Case Of The Missing Wrn Gene, Lisa Jeziorny, Lindsey Mccurdy, Katie Michael, Jennifer Riddle, Kim Silvers

Eukaryon

Werner Syndrome is an autosomal recessive disease characterized by genomic instability, accelerated telomere shortening, and premature aging. Also, Werner Syndrome patients experience increased cancer rates, believed to be directly related to the lack of interaction between the WRN gene and tumor suppressor gene p53. The WRN gene consists of three identical molecules and has both exonuclease and helicase activity, which work together in opposite directions. WRN has been shown to stimulate polymerase â, needed in DNA repair. WRN helicase activity can also bind and degrade G-quadruplexes, which inhibit transcription. Studies show that the tumor suppressor gene p53 co-localizes with WRN ...
