Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin May 2019

Novel Mechanisms And Biomarkers In Alcohol-Induced Organ Injury., Christine E. Dolin

Electronic Theses and Dissertations

Background. Ethanol (EtOH) consumption is known to affect multiple organs; this is unsurprising, as the concentration of EtOH in the blood at relevant doses reaches the millimolar range. The overarching goal of this dissertation was to elucidate mechanisms of alcohol-induced organ injury, specifically the effects of alcohol on the hepatic extracellular matrix (ECM) proteome, the alcoholic hepatitis (AH) plasma peptidome, and the effects of alcohol on the renal cortex proteome and transcriptome. Methods. Mice were pair-fed ethanol-containing liquid diet chronically, and then some mice were administered lipopolysaccharide (LPS). Liver sections from these mice were processed in a series of increasingly …


Characteristics And Outcomes Of Patients Discharged Home From An Emergency Department With Acute Kidney Injury: A Population-Based Cohort Study, Rey Acedillo Feb 2019

Characteristics And Outcomes Of Patients Discharged Home From An Emergency Department With Acute Kidney Injury: A Population-Based Cohort Study, Rey Acedillo

Electronic Thesis and Dissertation Repository

We designed a population-based cohort study to describe the characteristics and outcomes of 6346 adults discharged home from an emergency department (ED) with acute kidney injury (AKI). Within 30 days of discharge, 149 (2.3%) patients died (stage 1: 2.1%, stage 2: 5.2%, and stage 3 AKI: 15.9%). We also compared 30-day mortality to patients hospitalized with AKI and patients discharged home with no AKI in two separate propensity score-matched analyses. An ED discharge versus hospitalization was associated with lower 30-day mortality (3.0% vs. 11.9%, relative risk (RR): 0.25, 95% confidence interval (CI): 0.21-0.30). An ED discharge home with AKI versus …


The Effect Of Dorsal Rhizotomy On Renal Sodium Excretion Following Dorsal Spinal Stimulation, Tanko Tijani Ahmed Jan 2019

The Effect Of Dorsal Rhizotomy On Renal Sodium Excretion Following Dorsal Spinal Stimulation, Tanko Tijani Ahmed

Hypertension is one of the most common risk factors in the development of heart disease, stroke and end stage renal failure. Sympathetic overactivity is believed to be one of the main mechanism behind resistant hypertension. Renal denervation has been used to treat resistant hypertension, although this procedure is an invasive one. Spinal cord stimulation (SCS) is a known modality to treat ischemic pain, angina pectoris, and peripheral vascular diseases. In previous studies in this laboratory, unilateral spinal cord stimulation in spontaneously hypertensive rat (SHR) at 67% of the motor threshold increased urinary sodium and water excretion significantly, without affecting mean …


Factors Associated With Hospital Readmissions Among United States Dialysis Facilities, Amber B. Paulus Jan 2019

Factors Associated With Hospital Readmissions Among United States Dialysis Facilities, Amber B. Paulus

Theses and Dissertations

Hospital readmissions are a major burden for patients with end stage renal disease (ESRD). On average, one in three hospital discharges among patients with ESRD are followed by a readmission within 30 days. Currently, dialysis facilities are held accountable for readmissions via the ESRD Quality Incentive Program standardized readmission ratio (SRR) clinical measure. However, little is known about facility-level factors associated with readmission. Additionally, unlike other standardized measures of quality in the dialysis setting, incident patients within their first 90-days of dialysis are included in the performance calculation. This study analyzed CMS Dialysis Facility Report data from 2013 to 2016 …


Diuretic, Natriuretic, And Vasodepressor Activity Of A Lipid Fraction Enhanced In Medium Of Cultured Mouse Medullary Interstitial Cells By A Selective Faah Inhibitor, Zdravka P. Daneva Jan 2019

Diuretic, Natriuretic, And Vasodepressor Activity Of A Lipid Fraction Enhanced In Medium Of Cultured Mouse Medullary Interstitial Cells By A Selective Faah Inhibitor, Zdravka P. Daneva

Theses and Dissertations

The relationship between the endocannabinoid system in the renal medulla and the long-term regulation of blood pressure is not well understood. To investigate the possible role of the endocannabinoid system in renomedullary interstitial cells, mouse medullary interstitial cells (MMICs) were obtained, cultured and characterized for their responses to treatment with a selective inhibitor of fatty acid amide hydrolase (FAAH), PF-3845. Treatment of MMICs with PF-3845 increased cytoplasmic lipid granules detected by Sudan Black B staining and multilamellar bodies identified by transmission electron microscopy. HPLC analyses of lipid extracts of MMIC culture medium revealed a 205nm-absorbing peak that showed responsiveness to …
