Prediction Of Long-Term Intellectual And Neuropsychological Effects Of Closed Head Injury In Infants And Children, Tamara Sue Brenner

Loma Linda University Electronic Theses, Dissertations & Projects

The ability to predict long-term intellectual and neuropsychological outcome (1-7 years post-injury) in children (ages 1 week - 14 years at injury) with a history of closed head injury were investigated. Clinical indicators of injury severity including EEG reading and age at injury as well as ’H-MRS variables of NAA/Ch, Ch/Cr, and lactate presence accurately classified 100% of children as functioning either within or above the average range or below the average range for most outcome measures. Combined clinical and H-MRS variables accounted for approximately 50% of the variance in outcome confirming the validity of their predictive use and also …

Association Of Viral Genome With Graft Loss In Children After Cardiac Transplantation., Girish S. Shirali, J Ni, R E. Chinnock, J K. Johnston, G L. Rosenthal, N E. Bowles, J A. Towbin

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: The survival of recipients of cardiac allografts is limited by rejection, lymphoproliferative disease, and coronary vasculopathy. The purpose of this study in children who had received heart transplants was to evaluate the cardiac allografts for myocardial viral infections and to determine whether the presence of viral genome in the myocardium correlates with rejection, coronary vasculopathy, or graft loss.

METHODS: We enrolled heart-transplant recipients 1 day to 18 years old who were undergoing evaluation for possible rejection and coronary vasculopathy. Endomyocardial-biopsy specimens were evaluated for evidence of rejection with the use of standard criteria and were analyzed for the presence …

An Analysis Of The Changing Forces Behind Health Insurance Coverage Of Homebirth, Christina Anne Gasbarro

Dissertations and Theses

The expansion of managed care, which is premised on containing costs while maintaining market share, represents a radical transformation of the U.S. health care system. A central question for medical sociologists is to determine how the changes brought by managed care influence health insurance and health care options. In evaluating the impacts of managed care, obstetrics is a particularly important site of study. Part of this agenda involves gathering baseline data on a specific transformation in obstetrics practice new to the managed care scene: the emergence of health insurance coverage for the option of home birth. The research project detailed …

Regulation Of Blastocyst Formation., A J Watson, L C Barcroft

Obstetrics & Gynaecology Publications

Preimplantation or pre-attachment development encompasses the "free"-living period of mammalian embryogenesis, which directs development of the zygote through to the blastocyst stage. Blastocyst formation is essential for implantation, establishment of pregnancy and is a principal determinant of embryo quality prior to embryo transfer. Cavitation (blastocyst formation) is driven by the expression of specific sets of gene products that direct the acquisition of cell polarity within the trophectoderm, which is both the first epithelium of development and the outer cell layer encircling the inner cell mass of the blastocyst. Critical gene families controlling these events include: the E-cadherin-catenin cell adhesion family, …

The Effect Of Individual Counseling On Hope And Its Impact On The Utilization Of Services By Individuals With Hiv Disease, Barry Michael Vesciglio

All-Inclusive List of Electronic Theses and Dissertations

The interrelationships of participation in counseling, level of hope, and care service utilization in a sample of individuals with HIV disease was the focus of this study. It was hypothesized that individual counseling would improve an HIV-positive person's level of hope, and would increase participation in additional care services. It was also hypothesized that individuals with more hope would seek a greater number of care services. The Health Status Questionnaire, which contains the Hope Scale, and the Social Support Questionnaire were used to collect data. Participation in individual counseling was not related to level of hope. Additionally, stage of illness …

Impact Of Smoking On The Outcome Of Anterior Cervical Arthrodesis With Interbody Or Strut-Grafting., Alan Hilibrand, Mark A. Fye, Sanford E. Emery, Mark A. Palumbo, Henry H. Bohlman

Rothman Institute Papers

BACKGROUND: An increased rate of pseudarthrosis has been documented following posterolateral lumbar spine grafting in patients who smoke. This same relationship has been assumed for anterior cervical interbody grafting, but to our knowledge it has never been proven. This study compared the long-term radiographic and clinical results of smokers and nonsmokers who had undergone arthrodesis with autogenous bone graft following multi-level anterior cervical decompression for the treatment of cervical radiculopathy or myelopathy, or both.

METHODS: One hundred and ninety patients were followed clinically and radiographically for at least two years (range, two to fifteen years). Fifty-nine of the patients had …

Clumping Factor A Mediates Binding Of Staphylococcus Aureus To Human Platelets, Ian R. Siboo, Ambrose L. Cheung, Arnold S. Bayer, Paul M. Sullam

Dartmouth Scholarship

The direct binding of bacteria to platelets may be an important virulence mechanism in the pathogenesis of infective endocarditis. We have previously described Staphylococcus aureus strain PS12, a Tn551-derived mutant of strain ISP479, with reduced ability to bind human platelets in vitro. When tested in an animal model of endocarditis, the PS12 strain was less virulent than its parental strain, as measured by bacterial densities in endocardial vegetations and incidence of systemic embolization. We have now characterized the gene disrupted in PS12 and its function in platelet binding. DNA sequencing, Southern blotting, and PCR analysis indicate that PS12 contained two …

Abstract

OBJECTIVE:

To assess the efficacy of flexible intramedullary Ender nails for the treatment of tibial diaphyseal.

MATERIALS AND METHODS:

This is a retrospective review of patients treated with the Ender Nail for both open and closed tibial shaft fractures. Between January 1989 and December 1994, 43 fractures were treated with these nails. The configuration of each fracture was determined using the Orthopedic Trauma Association classification and the extent of soft tissue damage was assessed using the Gustilo and Anderson's classification. Four patients were excluded from the study due to inadequate follow-up. There were 27 closed and 12 open fractures. …

Induction Of Beta3-Integrin Gene Expression By Sustained Activation Of The Ras-Regulated Raf-Mek-Extracellular Signal-Regulated Kinase Signaling Pathway., Douglas Woods, Holly Cherwinski, Eleni Venetsanakos, Arun Bhat, Stephan Gysin, Martine Humbert, Paul F. Bray, Vicki L. Saylor, Martin Mcmahon

Cardeza Foundation for Hematologic Research

Alterations in the expression of integrin receptors for extracellular matrix (ECM) proteins are strongly associated with the acquisition of invasive and/or metastatic properties by human cancer cells. Despite this, comparatively little is known of the biochemical mechanisms that regulate the expression of integrin genes in cells. Here we demonstrate that the Ras-activated Raf-MEK-extracellular signal-regulated kinase (ERK) signaling pathway can specifically control the expression of individual integrin subunits in a variety of human and mouse cell lines. Pharmacological inhibition of MEK1 in a number of human melanoma and pancreatic carcinoma cell lines led to reduced cell surface expression of alpha6- and …

Thrombolytic Therapy For Acute Myocardial Infarction In The Elderly, Bernard Bun-Lap Wong, Wai-Hong Chen

Journal of the Hong Kong College of Cardiology

Acute myocardial infarction (MI) is a leading cause of morbidity and mortality in developed countries. Patients ≥75 years constitute up to 30% of the acute MI population and are associated with a 50% in-hospital mortality. Thrombolytic therapy was shown in a metaanalysis of 9 largest randomized controlled trials to reduce 35-day mortality. However, the benefit was observed mainly among patients < 75 years old. For patients ≥ 75 years, the 35-day mortality was 24.3% in those treated with thrombolytic therapy and 25.3% in the placebo group, a difference not reaching statistical significance.

Conversion Disorder: Difficulties In Diagnosis Using Dsm-Iv/Icd-10, E U. Syed, R Atiq, S Effendi, S Mehmud

Department of Psychiatry

Objective: Conversion disorder presents differently in various cultures. The commonest symptoms in the Asian subcontinent may be very different from those seen in Western Hemisphere. This causes some difficulty in making a diagnosis while using DSM-IV and ICD-10.METHOD: This study searched inpatient records for the last 10 years at the Aga Khan University and collected some demographic data as well as assessed the phenomenology of conversion disorder in the patient population.Results: We found unresponsiveness to be the most common symptom in this sample thus not exactly fitting the DSM-IV/ICD-10 picture.CONCLUSION: We observed that current criteria of conversion disorder as stated …

Sars, A Sara Homolog Repressible By Agr, Is An Activator Of Protein A Synthesis In Staphylococcus Aureus, Ambrose L. Cheung, Katherine Schmidt, Brian Bateman, Adhar C. Manna

Dartmouth Scholarship

The expression of protein A (spa) is repressed by global regulatory loci sarA and agr. Although SarA may directly bind to the spa promoter to downregulate spa expression, the mechanism by which agr represses spa expression is not clearly understood. In searching for SarA homologs in the partially released genome, we found a SarA homolog, encoding a 250-amino-acid protein designated SarS, upstream of the spa gene. The expression of sarS was almost undetectable in parental strain RN6390 but was highly expressed in agr and sarA mutants, strains normally expressing high level of protein A. Interestingly, protein A …
