Social Network Analysis (Sna) Of Clark County, Nevada Tuberculosis (Tb) Case And Contact Investigation Data To Determine Pediatric Risk Factors For Disease Transmission, Darin Michael Cozatt

UNLV Theses, Dissertations, Professional Papers, and Capstones

Within the spectrum of childhood (infancy, early childhood, middle childhood, and adolescence), TB is a priority disease, and preventive care is recommended by the American Academy of Pediatrics (AAP)/Bright Futures initiative (AAP, 2008). Within the early childhood stage (15 months to 4 years), TB is classified as "HR2" (high risk 2), behind lead poisoning, which is "HR1" (AAP, 2008), the highest risk within this age range. Within the middle childhood stage (5 to 10 years), TB becomes an HR1. TB is preventable, and targeted screening is the best prevention method. The AAP/Bright Futures initiative further specifies the risk based on …


Factor Structure Of The Cpt-Ii, Mary Vertinski Dec 2014

Factor Structure Of The Cpt-Ii, Mary Vertinski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study investigates the factor structure of the Conners' Continuous Performance Test-II (CPT-II) in four pediatric samples of participants: (a) patients with traumatic brain injury, (b) healthy controls, (c) patients with various clinical diagnoses, and (d) all of the previously mentioned subjects combined. Confirmatory factor analyses (CFA) were used to investigate a one-, three- and four-factor model fit of the data. None of the models examined were an adequate fit for the data; however, it appears that the four-factor model seemed to be the best fitting of the models examined. Failure to find reasonably adequate fit precluded further analyses.

Longer Gestation Among Children Born Full Term Influences Cognitive And Motor Development, Emma V. Espel, Laura M. Glynn, Curt A. Sandman, Elyssia Poggi Davis Nov 2014

Longer Gestation Among Children Born Full Term Influences Cognitive And Motor Development, Emma V. Espel, Laura M. Glynn, Curt A. Sandman, Elyssia Poggi Davis

Psychology Faculty Articles and Research

Children born preterm show persisting impairments in cognitive functioning, school achievement, and brain development. Most research has focused on implications of birth prior to 37 gestational weeks; however, the fetal central nervous system continues to make fundamental changes throughout gestation. Longer gestation is associated with reduced morbidity and mortality even among infants born during the period clinically defined as full term (37–41 gestational weeks). The implications of shortened gestation among term infants for neurodevelopment are poorly understood. The present study prospectively evaluates 232 mothers and their full term infants (50.4% male infants) at three time points across the first postnatal …

Hearing The Patient Voice: Using Video Intervention/Prevention Assessment To Understand Teens With Cystic Fibrosis, Susan Horky Lscw, Laura E. Sherman Msw, Julie Polvinen, Michael Rich Md

Patient Experience Journal

This qualitative study asked two questions: 1) How do teens with cystic fibrosis (CF) feel about their treatments; and 2) What factors lead teens to adhere, or not adhere, to treatments. To answer these questions we used an innovative approach (Video Intervention/Prevention Assessment or VIA), to learn about the experiences of teens with CF. We loaned video camcorders to teens with CF and asked them to create visual narratives of their lives. Researchers logged and coded videotapes, identifying themes that arose from the material. A primary theme was “Doctors don’t understand.” Participants also highlighted the value of routines and parental …

Subspecialty Surveillance Of Long-Term Course Of Small And Moderate Muscular Ventricular Septal Defect: Heterogenous Practices, Low Yield., Erik L. Frandsen, Aswathy V. House, Yunbin Xiao, David A. Danford, Shelby Kutty

Journal Articles: Pediatrics

BACKGROUND: No expert consensus guides practice for intensity of ongoing pediatric cardiology surveillance of hemodynamically insignificant small and moderate muscular ventricular septal defect (mVSD). Therefore, despite the well-established benign natural history of mVSD, there is potential for widely divergent follow up practices. The purpose of this investigation was to evaluate (1) variations in follow up of mVSD within an academic children's hospital based pediatric cardiology practice, and (2) the frequency of active medical or surgical management resulting from follow up of mVSD.

METHODS: We retrospectively reviewed records of 600 patients with isolated mVSD echocardiographically diagnosed between 2006 and 2012. Large …


The Translational Biology Of Remyelination: Past, Present, And Future, Robin J.M. Franklin, Vittorio Gallo Nov 2014

The Translational Biology Of Remyelination: Past, Present, And Future, Robin J.M. Franklin, Vittorio Gallo

Pediatrics Faculty Publications

Amongst neurological diseases, multiple sclerosis (MS) presents an attractive target for regenerative medicine. This is because the primary pathology, the loss of myelin-forming oligodendrocytes, can be followed by a spontaneous and efficient regenerative process called remyelination. While cell transplantation approaches have been explored as a means of replacing lost oligodendrocytes, more recently therapeutic approaches that target the endogenous regenerative process have been favored. This is in large part due to our increasing understanding of (1) the cell types within the adult brain that are able to generate new oligodendrocytes, (2) the mechanisms and pathways by which this achieved, and (3) …

Introduction

We hypothesized that nutritional deficiency would be common in a cohort of postpartum, human immunodeficiency virus (HIV)-infected women and their infants.

Methods

Weight and height, as well as blood concentrations of retinol, α-tocopherol, ferritin, hemoglobin, and zinc, were measured in mothers after delivery and in their infants at birth and at 6-12 weeks and six months of age. Retinol and α-tocopherol levels were quantified by high performance liquid chromatography, and zinc levels were measured by atomic absorption spectrophotometry. The maternal body mass index during pregnancy was adjusted for gestational age (adjBMI).

Results

Among the 97 women 19.6% were underweight. …

Atrx Is Required For Maintenance Of The Neuroprogenitor Cell Pool In The Embryonic Mouse Brain, Kieran Ritchie, L Ashley Watson, Benjamin Davidson, Yan Jiang, Nathalie G. Bérubé

Paediatrics Publications

Mutations in the alpha-thalassemia mental retardation X-linked (ATRX) gene cause a spectrum of abnormalities including intellectual disability, developmental delay, seizures, and microcephaly. The ATRX protein is highly enriched at heterochromatic repetitive sequences adjacent to the centromere, and ATRX depletion results in chromosome congression, segregation, and cohesion defects. Here, we show that Cre-mediated inactivation of Atrx in the embryonic mouse (Mus musculus) brain results in expansion of cerebral cortical layer VI, and a concurrent thinning of layers II-IV. We observed increased cell cycle exit during early-mid neurogenesis, and a depletion of apical progenitors by late neurogenesis in the Atrx-null neocortex, explaining …

Coagulopathy In Newborns With Hypoxic Ischemic Encephalopathy (Hie) Treated With Therapeutic Hypothermia: A Retrospective Case-Control Study, Katie R. Forman, Yaser A. Diab, Edward C.C. Wong, Stephen Baumgart, Naomi L. Luban, An Nguyen Massaro

Pediatrics Faculty Publications

Background

Newborns with hypoxic ischemic encephalopathy (HIE) are at risk for coagulopathy due to systemic oxygen deprivation. Additionally, therapeutic hypothermia (TH) slows enzymatic activity of the coagulation cascade, leading to constitutive prolongation of routinely assessed coagulation studies. The level of laboratory abnormality that predicts bleeding is unclear, leading to varying transfusion therapy practices.

Methods

HIE infants treated with TH between 2008–2012 were included in this retrospective study. Initial, minimum (min) and maximum (max) values of International Normalized Ratio (INR), activated partial thromboplastin time (aPTT), fibrinogen (Fib) and platelet (PLT) count (measured twice daily during TH) were collected. Bleeding was defined …

Evidence-Informed Guidelines For Pediatric Pandemic Planning And Response, Ginny Sprang, James J. Clark, Miriam Silman, Phyllis W. Leigh, Candice M. Jackson, A. Scott Lajoie

Center on Trauma and Children Reports

From the executive summary:

Pandemic events are unpredictable and inevitable. When they occur, the impact is both all-encompassing and asymmetrical; each pandemic targets specific, vulnerable populations, but ultimately impacts individuals, families and communities throughout the world. Regardless of origin or circumstances, the next pandemic will certainly count infants, children, and adolescents among its most vulnerable targets. As evidenced by the 2009 H1N1 influenza pandemic, children may be at higher risk than populations more typically seen as susceptible to pandemic illness (the elderly, those with weakened immune systems, etc.). Children also can function as disease vectors, spreading the virus through their …

Pediatrics Faculty Publications

OBJECTIVE:

Chronic neurological deficits are a significant complication of preterm birth. Magnesium supplementation has been suggested to have neuroprotective function in the developing brain. Our objective was to determine whether higher neonatal serum magnesium levels were associated with better long-term neurodevelopmental outcomes in very-low birth weight infants.

STUDY DESIGN:

A retrospective cohort of 75 preterm infants (<1500 g, gestational age <27 weeks) had follow-up for the outcomes of abnormal motor exam and for epilepsy. Average total serum magnesium level in the neonate during the period of prematurity was the main independent variable assessed, tested using a Wilcoxon rank-sum test.

RESULTS:

Higher average serum magnesium level was associated with a statistically significant decreased risk for abnormal motor exam (p = 0.037). A lower risk for epilepsy in the group with higher magnesium level did not reach statistical significance (p = 0.06).

CONCLUSION:

This …

Vascular Ehlers-Danlos Syndrome: A Rare Disorder Presenting With Focal Convulsions, Shakeel Ahmed, Syed Rehan Ali, Naila Nadeem, Muhammad Hamid

Department of Paediatrics and Child Health

Vascular Ehlers-Danlos Syndrome (VEDS), previously called Ehlers-Danlos syndrome type-IV, is a heterogeneous group of heritable connective tissue disorders characterized by thin, translucent skin, easy bruising, arterial, intestinal, and/or uterine fragility. There is large vessel involvement that leads to arterial rupture often preceded by aneurysm, arteriovenous fistulae, or dissection. Noninvasive imaging studies such as CT angiography and MR angiography are preferred as diagnostic studies for this condition. We are reporting a 4 years old girl who was presented with right sided unilateral convulsions and hypertension. CT angiogram showed stenosis with post-stenotic dilatation of coeliac and superior mesenteric arteries. There were extensive …

Purpose

The presence of diffuse anaplasia in Wilms tumours (DAWT) is associated with TP53 mutations and poor outcome. As patients receive intensified treatment, we sought to identify whetherTP53 mutational status confers additional prognostic information.

Patients and Methods

We studied 40 patients with DAWT with anaplasia in the tissue from which DNA was extracted and analysed for TP53 mutations and 17p loss. The majority of cases were profiled by copy number (n = 32) and gene expression (n = 36) arrays. TP53 mutational status was correlated with patient event-free and overall survival, genomic copy number instability and gene expression profiling. …


Neonatal Nmda Receptor Blockade Disrupts Spike Timing And Glutamatergic Synapses In Fast Spiking Interneurons In A Nmda Receptor Hypofunction Model Of Schizophrenia, Kevin S. Jones, Joshua G. Corbin, Molly M. Huntsman Oct 2014

Neonatal Nmda Receptor Blockade Disrupts Spike Timing And Glutamatergic Synapses In Fast Spiking Interneurons In A Nmda Receptor Hypofunction Model Of Schizophrenia, Kevin S. Jones, Joshua G. Corbin, Molly M. Huntsman

Pediatrics Faculty Publications

The dysfunction of parvalbumin-positive, fast-spiking interneurons (FSI) is considered a primary contributor to the pathophysiology of schizophrenia (SZ), but deficits in FSI physiology have not been explicitly characterized. We show for the first time, that a widely-employed model of schizophrenia minimizes first spike latency and increases GluN2B-mediated current in neocortical FSIs. The reduction in FSI first-spike latency coincides with reduced expression of the Kv1.1 potassium channel subunit which provides a biophysical explanation for the abnormal spiking behavior. Similarly, the increase in NMDA current coincides with enhanced expression of the GluN2B NMDA receptor subunit, specifically in FSIs. In this study mice …

Intellectual And Developmental Disability: Healthcare Financing, David A. Ervin, Joav Merrick

Pediatrics Faculty Publications

The World Health Organization (WHO) estimates global spending on healthcare at $6.5 trillion, approximately 10.5% of the world’s gross domestic product. The United States’ (US) share of that spending is $2.6 trillion, essentially quadrupling since 1980. The 2010 United States Patient Protection and Affordable Care Act (PPACA), also known as Obamacare, has stimulated extensive debate over the way in which healthcare is financed, and whether or not the costs of healthcare are sustainable. Among publicly funded healthcare in the US, Medicaid and Medicare are primary sources of funding. In federal fiscal year 2012, Medicaid spending on acute health exceeded $275.4 …

Pediatrics Faculty Publications

Induction of fetal hemoglobin (HbF) has therapeutic importance for patients with sickle cell disease (SCD) and the beta-thalassemias. It was recently reported that increased expression of LIN28 proteins or decreased expression of its target let-7 miRNAs enhances HbF levels in cultured primary human erythroblasts from adult healthy donors. Here LIN28A effects were studied further using erythrocytes cultured from peripheral blood progenitor cells of pediatric subjects with SCD. Transgenic expression of LIN28A was accomplished by lentiviral transduction in CD34(+) sickle cells cultivated ex vivo in serum-free medium. LIN28A over-expression (LIN28A-OE) increased HbF, reduced beta (sickle)-globin, and strongly suppressed …
