Paediatric Surgical Outcomes Across Ontario, Damian Dylkowski
Paediatric Surgical Outcomes Across Ontario, Damian Dylkowski
Electronic Thesis and Dissertation Repository
BACKGROUND: The purpose of this study was to determine the volume of three complex paediatric procedures at the tertiary care centres in Ontario over the last 20 years in three disciplines, analyze outcomes and explore the possibility of an outcome volume relationship.
METHODS: A population based cohort study of patients undergoing TEF repair, Pyeloplasty and V-P shunt insertion at 4 paediatric centres in Ontario between 1993 and 2013 was carried out. Administrative data sets were linked using unique encoded identifiers and analyzed at the Institute for Clinical Evaluative Sciences (ICES).
RESULTS: In TEF repair and Pyeloplasty, there was significant difference …
Translational Study Of Liver Cancer And Hypertrophy: Translich, Mauro Enrique Tun Abraham
Translational Study Of Liver Cancer And Hypertrophy: Translich, Mauro Enrique Tun Abraham
Electronic Thesis and Dissertation Repository
Abstract
Background: Associating liver partition with portal vein ligation for staged-hepatectomy (ALPPS) is a technique for inducing accelerated hypertrophy in patients with insufficient future liver remnant (FLR). It remains unknown whether this hypertrophy may lead to rapid cancer cell dissemination and/or alteration of immune cell/function reconstitution in the FLR. We aimed to determine if the rapid hypertrophy during ALPPS procedure results in more circulating tumour cell (CTCs) dissemination and whether the FLR remains immunologically competent in patients with CRLM.
Methods: In our prospective, observational, 2-arm study, we assessed the utility of CTCs as an evaluation tool for disease dissemination. Moreover, …
Early Experimental Results Of Using A Novel Delivery Carrier, Hyaluronan-Phosphatidylethanolamine (Ha-Pe) Which May Allow Simple Bladder Instillation Of Botulinum Toxin A As Effectively As Direct Detrusor Muscle Injection., Mohamed G. El Shatoury
Electronic Thesis and Dissertation Repository
Intra-detrusor Botulinum Toxin-A (BTX-A) injection is the gold standard treatment for detrusor overactivity in clinical practice when medical treatment fails. Despite satisfactory results of BTX-A injection, the endoscopic procedure still has risks of anaesthetic and operative complications. Several studies have investigated more simple ways to deliver BTX-A to the detrusor muscle but with limited success. In our study, we assessed the evidence of BTX-A delivery using a newly modulated hyaluronan-phosphatidylethanolamine (HA-PE) carrier in a rat model through BTX-A-HA-PE bladder instillations. We used histological evidence of SNAP-25 protein cleavage and detection of Alexa FluorÒ594-labelled BTX-A as a proof of physical BTX-A …
Protective Benefits Of Hydrogen Sulfide Treatment During Renal Transplantation, Ian Lobb
Protective Benefits Of Hydrogen Sulfide Treatment During Renal Transplantation, Ian Lobb
Electronic Thesis and Dissertation Repository
Ischemia/reperfusion injury (IRI) is inherent to renal transplantation (RTx) and is initiated when blood supply is necessarily removed during organ procurement (ischemia) and subsequently restored upon engraftment (reperfusion). During renal ischemia, ATP depletion causes tubular epithelial cell (TEC) injury and subsequent release of pro-inflammatory mediators. Upon reperfusion, influx of O2 causes reactive oxygen species (ROS) production and infiltration of innate immune cells which release damaging ROS and proteases. Prolonged periods of IRI are associated with increased risk of delayed graft function (DGF) and decreased long-term graft survival. The endogenously produced gasotransmitter, hydrogen sulfide (H2S), has recently been …
Inpatient Versus Outpatient Total Hip Arthroplasty, Michael Pollock
Inpatient Versus Outpatient Total Hip Arthroplasty, Michael Pollock
Electronic Thesis and Dissertation Repository
We conducted a randomized controlled trial to evaluate patients undergoing a total hip arthroplasty (THA) who were discharged from the hospital either on the day of surgery (outpatient) or were admitted overnight following surgery (inpatient). Our primary outcome was the rate of serious adverse events during the first three months postoperatively. Secondary outcome measures included cost, patient satisfaction, functional outcomes, quality of life and pain. We found no statistically significant difference between the two groups in serious adverse events. We found that outpatient THA was less expensive from the perspectives of the hospital and ministry of health; but the difference …
