Biomarkers Of Sepsis: A Retrospective Approach, 2017 The University of Akron
Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts
Williams Honors College, Honors Research Projects
Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.
Objectives: To evaluate the use of biomarkers in children seen in the Emergency ...
Halo- And Solvato-Fluorochromic Polymer Nanoassemblies For Cancer Theranostics, 2017 University of Kentucky
Halo- And Solvato-Fluorochromic Polymer Nanoassemblies For Cancer Theranostics, Derek Alexander Reichel
Theses and Dissertations--Pharmacy
Theranostics is an emerging treatment approach that combines diagnostics with therapy in order to personalize treatment regimens for individual patients and decrease cancer mortality. Previously, nanoparticles entrapping conventional fluorescent dyes were developed for cancer theranostics, but fluorescent nanoparticles did not allow clinicians to significantly improve cancer treatments.
The use of fluorescent dyes that are sensitive to solvent acidity (halo-fluorochromism) and polarity (solvato-fluorochromism) may overcome the limitations of fluorescent nanoparticles and improve cancer therapy by enabling researchers to detect chemical properties within the nanoparticle core environment. The model halo- and solvato-fluorochromic dye Nile blue was attached to the core of nanoscale ...
Mri-Based Susceptibility Mapping For In-Vivo Iron And Blood Oximetry Measurements, 2017 University of Colorado, Boulder
Mri-Based Susceptibility Mapping For In-Vivo Iron And Blood Oximetry Measurements, Hannah Erdevig
Undergraduate Honors Theses
MRI is increasingly used in mapping tissue susceptibility to identify cerebral microbleeds associated with traumatic brain injury and pathological iron deposits associated with neurodegenerative diseases such as Parkinson's and Alzheimer's disease [1,2]. Accurate measurement is important for determining oxygen and iron content in blood vessels and tissue in the brain, which are in turn used for noninvasive clinical diagnosis and treatment assessments. Magnetic field distortions with a resolution of a few parts per billion can be measured using MRI phase maps. The field distortion map can then be inverted to obtain a quantitative susceptibility map. The primary ...

Chronic wounds, in particular venous leg ulcers (VLU), represent a substantial burden for economies, healthcare systems and societies worldwide. This burden is exacerbated by the recalcitrant nature of these wounds, despite best practice, evidence-based care, which substantially reduces the quality of life of patients. Furthermore, co-morbidities such as diabetes and cardiovascular disease within ageing populations further contribute to the increasing prevalence in developed countries. This review provides an overview of the literature concerning the cellular and molecular mechanisms of wound healing and aspects where this process fails, resulting in a chronic wound. VLU may arise from chronic venous disease, which ...
Enhanced Breast Cancer Classification With Automatic Thresholding Using Support Vector Machine And Harris Corner Detection, 2017 South Dakota State University
Enhanced Breast Cancer Classification With Automatic Thresholding Using Support Vector Machine And Harris Corner Detection, Mohammad Taheri
Electronic Theses and Dissertations
Image classification and extracting the characteristics of a tumor are the powerful tools in medical science. In case of breast cancer medical treatment, the breast cancer classification methods can be used to classify input images as benign and malignant classes for better diagnoses and earlier detection with breast tumors. However, classification process can be challenging because of the existence of noise in the images, and complicated structures of the image. Manual classification of the images is timeconsuming, and need to be done only by medical experts. Hence using an automated medical image classification tool is useful and necessary. In addition ...
Concerns About Justification For Fetal Genome Sequencing, 2016 S.J. Quinney College of Law, University of Utah
Concerns About Justification For Fetal Genome Sequencing, Leslie Francis
Utah Law Faculty Scholarship
The proposal by Chen and Wasserman (2017) contributes to a long-standing debate about the scope of prenatal screening services. With realistic prospects of fetal genome-scale sequencing from noninvasive maternal blood sampling (NIPW), their framework is timely. However, we outline a number of concerns regarding this approach, ranging from the philosophical to the social and clinical. A key concern in this literature is that the framework lacks a clear philosophical foundation. Despite the long history of prenatal diagnosis (PND), a central question remains regarding the core justification for these services.

A 7-year-old previously healthy girl presented with a left-sided focal seizure without impaired consciousness and subsequently developed epilepsia partialis continua. Initial MRI was normal, and the subsequent images only showed a focal T2/FLAIR hyperintense area without cortical atrophy. She was diagnosed with Rasmussen syndrome by pathology and promptly treated with functional hemispherotomy. Rasmussen syndrome is a rare progressive neurological disorder, the only definitive cure for which is hemispheric disconnection. The disease presents a management dilemma, especially early in disease course without characteristic neuroimaging features. A high index of suspicion, multidisciplinary approach, and clear timely communication with the family are ...
Investigations Into The Effects Of Water Exchange And The Structure Of Lanthanide Chelates, 2016 Portland State University
Investigations Into The Effects Of Water Exchange And The Structure Of Lanthanide Chelates, Katherine Marie Payne
Dissertations and Theses
Lanthanide chelates are effective agents for improving contrast in MR images. Optimizing the relaxation of inner sphere water molecules is a common focus of research in this field. However, the efforts to design an optimal contrast agent have commonly over-looked the relationship of water position and water exchange kinetics. This work explores structural conformation, the impact of very fast water exchange kinetics on hydration, and differing tumbling rates for regioisomers of a number of lanthanide chelates. We have grown crystals of LnDOTMA and obtained structural data by X-ray diffraction that provide a picture of the chelate during water exchange and ...
Barriers To Completion Of A Family Health History Tool And Increasing Subject Retention, 2016 University of North Texas Health Science Center at Fort Worth
Barriers To Completion Of A Family Health History Tool And Increasing Subject Retention, Margarett A. Bennett
Theses and Dissertations
Family Health Histories (FHH) are crucial for identifying disease risk factors, and such information is paramount to the diagnosis, treatment, and long term care of patients. Many if not most human diseases include a hereditary component. Despite the recognized importance of health history information, the FHH of many Americans remains uncaptured. This study examined impediments to FHH completion and evaluated a strategy for increasing completion. Participants were givenreminder prompts, offers of assistance, and surveyed to identify barriers and effective methods to improve FHH completion. The most frequently cited barrier was that the participant did not remember being part of the ...

Does The Electronic Health Record Improve The Timeliness Review And Notification Of Medical Laboratory And X-Ray Test Results?, Ruby Estes
Applied Research Projects
The medical community struggles with timeliness issues throughout the different healthcare environments in many areas of patient care. The demands of meeting patient care needs is great everywhere. One area that can lead to extreme adverse outcomes and affects patient safety is failure to review and follow-up on medical test results timely. In addition the lack of timely follow-up and treatment can lead to medico-legal implications for all healthcare professionals involved in the patients care. Some timeliness issues have been attributed to understaffed healthcare institutions, lack of trained staff, and in many instances inefficient and insufficient processes. This is an ...

Study Of Kinematics And Gait In Dynamic Response Feet Across Functional K-Level Categories., Russell J. Donevant
Theses and Dissertations
In the United States, the Medicare Functional Classification Level (MFCL or K-level) classification system exists in order to estimate a patient’s rehabilitation potential. Physicians assign a K-level rating from 0-4 of increasing functionality, which serves to designate what kind of prosthetic device to provide a patient with and what insurance will cover. This study aims to interpret kinematic data recorded from transtibial amputees with two different functional levels of prosthetic feet and interpret the effect on gait and functional performance when switching to a higher/lower prosthetic level than the one currently equipped with. Kinematic data are collected via ...

Late Onset Of Pulmonary Hypertension And Sepsis In Omphalocele Infants, 2016 Children's Mercy Hospital
Late Onset Of Pulmonary Hypertension And Sepsis In Omphalocele Infants, Joanne E. Baerg, Arul Thirumoorthi, Whitney Carlton, Shelly Haug, Andrew O. Hopper, Donna Goff, Sandhya Ramlogan, Shawn D. St Peter
Manuscripts, Articles, Book Chapters and Other Papers
A subset of omphalocele infants has respiratory decompensation after the first week of life and PHN is diagnosed. Infection may initiate decompensation. In some, PHN is distinct from pulmonary hypoplasia as they oxygenate on room air for some time after birth. With aggressive treatment and follow-up, PHN can resolve. The late diagnosis of PHN in infants with omphalocele is previously unappreciated and deserves further study.

INTRODUCTION: Obesity is a growing epidemic fuelled by unhealthy behaviours and associated with significant comorbidities and financial costs. While behavioural interventions produce clinically meaningful weight loss, weight loss maintenance is challenging. This may partially be due to failure to target stress and emotional reactivity. Mindfulness-based stress reduction (MBSR) reduces stress and emotional reactivity and may be a useful tool for behaviour change maintenance. This study seeks to provide a mechanistic understanding for clinical trials of the benefits of MBSR for weight loss maintenance by examining changes in functional connectivity (FC) and the association of these changes with clinical outcomes.
Can Bedside Ultrasound Inferior Vena Cava Measurements Accurately Diagnose Congestive Heart Failure In The Emergency Department? A Clin-Iq, Miranda Gaskamp, Mark Blubaugh, Laine H. Mccarthy, Dewey C. Scheid
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 ...
