Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal 2019 Louisiana State University and Agricultural and Mechanical College

Scintillation Event Localization In Novel Hemi-Ellipsoid Detector For Spect, Hanif R. Soysal

LSU Master's Theses

A high sensitivity Cardiac SPECT system using hemi-ellipsoid crystals with pinhole collimation was previously proposed by Dey et al. To investigate detector resolution for this design, the scintillation light spread on a monolithic hemi-ellipsoidal CsI crystal was simulated using Geant4 Monte Carlo. The expected distribution of scintillation light on the outer surface of the crystal from photoelectric absorption events was obtained from the simulations for selected points inside the crystal. Two sets of simulations were performed. For the first set, a look-up table (LUT) of 12 points was created and each point mapped to its expected light distribution—four points ...

Differential Estimation Of Audiograms Using Gaussian Process Active Model Selection, Trevor Larsen 2019 Washington University in St. Louis

Differential Estimation Of Audiograms Using Gaussian Process Active Model Selection, Trevor Larsen

Engineering and Applied Science Theses & Dissertations

Classical methods for psychometric function estimation either require excessive resources to perform, as in the method of constants, or produce only a low resolution approximation of the target psychometric function, as in adaptive staircase or up-down procedures. This thesis makes two primary contributions to the estimation of the audiogram, a clinically relevant psychometric function estimated by querying a patient’s for audibility of a collection of tones. First, it covers the implementation of a Gaussian process model for learning an audiogram using another audiogram as a prior belief to speed up the learning procedure. Second, it implements a use case ...


Simulating Alternative Tuberculosis Diagnosis Methods In Underdeveloped Countries, Luke Turner 2019 University of Arkansas, Fayetteville

Simulating Alternative Tuberculosis Diagnosis Methods In Underdeveloped Countries, Luke Turner

Industrial Engineering Undergraduate Honors Theses

Tuberculosis is the deadliest infectious disease in the world; it is especially rampant in underdeveloped countries because they do not have the infrastructure, technology, or funding to properly combat the infection. However, the development of portable point-of-care diagnosis machines can reverse this epidemic as they far surpass conventional laboratory identification. The question now is where to place these machines, which is a difficult decision with a lack of data. Therefore, a flexible simulation model is created to test the implementation of these machines with different countries and configurations. The simulation tests the baseline model and three proposed implementations of the ...

Suffering In Silence: Is Gastroparesis Underdiagnosed?, Dennis J. Baumgardner 2019 Aurora UW Medical Group, Aurora Health Care

Suffering In Silence: Is Gastroparesis Underdiagnosed?, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

In this introduction to Volume 6, Issue 2, the editor-in-chief of the Journal of Patient-Centered Research and Reviews offers additional comment to the clinical review of diabetic gastroparesis authored by Farmer and colleagues (p. 148), regarding the problem of undiagnosed disease. Increased awareness of this entity and appropriate questioning regarding symptoms of diabetic gastroparesis in the primary care setting may prevent the “suffering in silence” experienced by many patients with this complication.

Synthesis Of A Zn(Ii)-Responsive Paracest Mri Agent For Improved Diagnosis Of Prostate Cancer, Megan Martin, Holly Clancy 2019 The University of San Francisco

Synthesis Of A Zn(Ii)-Responsive Paracest Mri Agent For Improved Diagnosis Of Prostate Cancer, Megan Martin, Holly Clancy

Creative Activity and Research Day - CARD

In the United States, prostate cancer is the leading type of cancer diagnosed in men. Prostate cancer is currently diagnosed with the Prostate-Specific Antigen (PSA) test; however, it leads to many false positives and therefore unneeded biopsies. Previous studies have shown that cancerous prostates have a much lower concentration of zinc than healthy prostates. The goal of this project is to create an MRI contrast agent capable of non-invasively quantifying zinc in the human prostate. Five out of the eight synthetic steps have been successfully completed so far, and the identities of these intermediate products have been verified by 1 ...

Inclusion Body Myositis, Sreelakshmi Panginikkod, Rina Musa

Open Access Articles

Inclusion body myositis (IBM) is the most common subtype of autoimmune myopathy in patients older than the age of 50 years. Several diagnostic criteria have been proposed for IBM based on expert opinion and consensus groups. Their use in clinical practice is however limited due to low sensitivity. The European Neuromuscular Centre (ENMC) 2011 clinically defined diagnostic criteria have a high specificity of greater than 99% to diagnose IBM, but like other criteria, its sensitivity is low at 57%. ENMC 2011 Inclusion Body Myositis Diagnostic Criteria Mandatory Features: 1. Age of onset later than 45 years. 2. Duration of symptoms ...


Uhthoff Phenomenon, Sreelakshmi Panginikkod, Lokesh A.. Rukmangadachar 2019 University of Massachusetts Medical School

Uhthoff Phenomenon, Sreelakshmi Panginikkod, Lokesh A.. Rukmangadachar

Open Access Articles

Uhthoff's phenomenon (also known as Uhthoff sign or Uhthoff syndrome) is described as temporary, short-lived (less than 24 hours) and stereotyped worsening of neurological function among multiple sclerosis patients in response to increases in core body temperature. This phenomenon is named after Wilhelm Uhthoff, a German ophthalmologist who described it. In 1890, Uhthoff first described exercise-induced amblyopia in multiple sclerosis patients. In 1961, this phenomenon was given his surname, Uhthoff's Phenomenon (UP), by G. Ricklefs[1]. In four out of 100 MS patients, Uhthoff observed the appearance of reversible optic symptoms induced by an increase in body temperature ...


Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente 2019 Duquesne University

Aortoduodenal Fistula Forms From Primary Aortic Stump Graft In A Two-Time Multi-Visceral Transplant Patient With Presentation Of Gastrointestinal Bleed And Bowel Perforation: A Case Report, Brielle Corrente

Graduate Student Research Symposium

Usually not diagnosed until open laparotomy, aortoduodenalfistulas (ADF) are one of the rarest complications of intestinal transplant surgery. With an incidence rate of only 0.04% at autopsy and only 250 documented cases since the early 1800’s, aortoduodenal fistulas are the most deadly complications of intestinal transplantation with a mortality rate of 100% without surgical intervention. A 39 year old, two-time multi-visceral transplant African American female patient suffered from a primary aortoduodenal fistula formation in a primary modified multi-visceral transplant aortic stump graft site. With emergency open laparotomy repair, revascularization of the secondary multi-visceral transplant was performed, saving the ...

Assessment Of The Potential Use Of Recombinant Baculovirus-Expressed Lassa Virus Nucleoprotein As A Serodiagnostic Antigen, Sahiba Grover

Kansas State University Undergraduate Research Conference

Lassa virus is an arenavirus causing a disseminated systemic primary viral infection. This virus causes Lassa fever which is a viral hemorrhagic fever endemic in West Africa and is responsible for the deaths of thousands of people each year. There is a possibility for the Lassa virus to be introduced into the US and used as a biological weapon with the potential to harm a large-scale population. Because of increasing international travel, a sizeable burden from the disease, and its potential use for biological warfare, it is necessary to develop sensitive diagnostic assays to accurately detect virus infections and mitigate ...

Two Unique Cases Of X-Linked Scid: A Diagnostic Challenge In The Era Of Newborn Screening, Pooja Purswani, Anne Marie Comeau, Jaime E. Hale, Jolan E. Walter

Open Access Articles

In the era of newborn screening (NBS) for severe combined immunodeficiency (SCID) and the possibility of gene therapy (GT), it is important to link SCID phenotype to the underlying genetic disease. In western countries, X-linked interleukin 2 receptor gamma chain (IL2RG) and adenosine deaminase (ADA) deficiency SCID are two of the most common types of SCID and can be treated by GT. As a challenge, both IL2RG and ADA genes are highly polymorphic and a gene-based diagnosis may be difficult if the variant is of unknown significance or if it is located in non-coding areas of the genes that are ...

Objectives: Diabetic cardiomyopathy (DCM) is an established complication of diabetes mellitus. In West Virginia, the especially high incidence of diabetes and heart failure validate the necessity of developing new strategies for earlier detection of DCM. Since most DCM patients remain asymptomatic until the later stages of the disease when the fibrotic complications become irreversible, we aimed to explore biomarkers that can identify early-stage DCM.

Methods: The patients were grouped into 4 categories based on clinical diabetic and cardiac parameters: Control, Diabetes (DM), Diastolic dysfunction (DD), and Diabetes with diastolic dysfunction (DM+DD), the last group being the preclinical DCM group ...
