A Clinico-Pathological Study Of The Structural And Functional Changes In The Retina And Optic Nerve Following Diabetic Retinopathy Treatments, Richard Filek

Electronic Thesis and Dissertation Repository

Diabetic retinopathy (DR) is the result of microvascular changes in the retina due to hyperglycemia which alter the blood-retinal barrier (BRB). The increased permeability of BRB results in the accumulation of extracellular fluid, the development of diabetic macular edema (DME) and capillary occlusion. Capillary occlusion results in retinal ischemia which increases vascular endothelial growth factor (VEGF) levels, increases vascular permeability and results in neovascularization in proliferative diabetic retinopathy (PDR) patients. The treatments clinically used for DR are panretinal photocoagulation (PRP) for PDR and injectable vascular endothelial growth factor inhibitors (anti-VEGFs) for DME.

The safety of PRP and anti-VEGF therapy on …

Journal of Bioresource Management

Typhoid is caused by Salmonella enterica serovar Typhi that is usually diagnosed by using serologic and immuno-chromatographic techniques in developing counties including Pakistan, which is thought to be an unreliable diagnostic method. For accurate diagnosis we used molecular techniques to amplify 204 bp StyR-36 and 498 bp flagellin gene for the identification of Salmonella enterica serovar Typhi. This study was done on 58 individuals diagnosed positive of typhoid via serologic tests and 50 healthy individuals as a control group. Success rate of amplification for flagellin gene was 77.58% while that for StyR-36 gene was 68.97% showing that flagellin gene primer …

Sepsis, Sarah Jones

Nursing Student Class Projects (Formerly MSN)

Sepsis is a dysregulation of the inflammatory response, termed systemic inflammatory response syndrome or SIRS, caused by stimulation of an infectious process. Sepsis often leads to organ dysfunction and increased morbidity, mortality and financial burdens. The goal of treatment is to initiate appropriate antimicrobial therapies, target the underlying infection, optimize intravascular volume, provide fluid resuscitation and maintain adequate perfusion and stroke volume (Taeb, Hooper & Marik, 2017).

Timing of treatment and early detection of sepsis is critical to patients with early warning signs. Sharing this information and potentially making a difference in the outcomes of patients presenting with early signs …

Pain And Pharmacologic Pain Management In Long-Stay Nursing Home Residents, Jacob N. Hunnicutt, Christine M. Ulbricht, Jennifer Tjia, Kate L. Lapane

Jennifer Tjia

Prior studies estimate that >40% of long-stay nursing home (NH) residents experience persistent pain, with 20% of residents in pain receiving no analgesics. Strengthened NH surveyor guidance and improved pain measures on the Minimum Data Set (MDS) 3.0 were introduced in March 2009 and October 2010, respectively. This study aimed to provide estimates after these important initiatives of: 1) prevalence and correlates of persistent pain; and 2) prevalence and correlates of untreated or undertreated persistent pain. We identified 1,387,405 long-stay residents in United States NHs between 2011-2012 with 2 MDS assessments 90 days apart. Pain was categorized as persistent (pain …

Performance Of Non-Invasive Tests To Predict Significant Liver Fibrosis In Patients With Morbid Obesity, Ahmed Bakhshwin, Patricia Latham

GW Research Days 2016 - 2020

Non-Alcoholic Fatty Liver Disease (NAFLD) affects more than 90% of patients with morbid obesity (MO) and approximately 30% have significant liver fibrosis and/or cirrhosis. Liver biopsy is the gold standard for diagnosis of significant liver fibrosis and cirrhosis; however, several non-invasive tests have been suggested to predict the presence or absence of significant liver fibrosis and to avoid liver biopsy in these patients. The aim of this study was to determine the ability of these tests to predict significant liver fibrosis, specifically in patients with MO.

Methods:

Liver biopsies from patients with MO undergoing gastric bypass surgery were studied in …

Empty Nose Syndrome—What Do We Know?, Ethan Frank, Christopher Church Md

Loma Linda University Student Journal

Empty nose syndrome is a complication of nasal surgery wherein patients develop a persistent, debilitating sense of nasal obstruction and dyspnea despite clear nasal cavities. It is characterized by a discrepancy between prominent subjective symptoms and near total lack of objective findings, making it difficult to diagnose. The pathophysiology of empty nose syndrome is a complex mix of aerodynamic, physiologic, and neurological changes leading to altered airflow and diminished sensory function. Evolving treatment options consist of medical symptom control or surgical reconstruction.

Orientia Tsutsugamushi Secretes Two Ankyrin Repeat-Containing Effectors Via A Type 1 Secretion System To Inhibit Host Nf-Κb Function, Sean M. Evans

Theses and Dissertations

Scrub typhus is a potentially fatal infection that threatens one billion persons in the Asia-Pacific region and is caused by the obligate intracellular bacterium, Orientia tsutsugamushi. How this organism facilitates its intracellular survival and pathogenesis is poorly understood. Intracellular bacterial pathogens utilize the Type 1 (T1SS) or Type 4 secretion system (T4SS) to translocate ankyrin repeat-containing proteins (Anks) into the host cell to modulate host cell processes. The O. tsutsugamushi genome encodes one of the largest known bacterial Ank libraries as well as Type 1 and Type 4 secretion systems (T1SS and T4SS), which are expressed during infection. In …
