Filter by:This project aims at investigating the duration of human fecal carriage of bacteria harboring plasmid-borne resistance genes expressing Extended Spectrum beta-lactamases (ESBL), risk factors for infections with such bacteria and persistence, mobility and spread of ESBL in the environment and within households. It also aims to compare different methods of detecting ESBL carriage and treat patients with urinary tract infection caused by these bacteria.
Background: There are no published studies regarding the use of wound protectors in the context of surgical site infection (SSI) rates among patients receiving a pancreatoduodenectomy (Whipple) with preoperatively placed intrabiliary stents. In high volume experiences, the SSI rate is 40-50% within this cohort. In Calgary, preoperative biliary stent placement for bile duct decompression represents the norm given typical surgical wait times. In addition to having higher associated lengths of hospital stay, ICU admissions, hospital re-admissions, and overall mortality, patients with SSI are also delayed, and often omitted, in their progression to critical oncologic adjuvant chemotherapy. As a result, SSI remain crucial and devastating complications for pancreas surgeons and their patients alike. Methods: The investigators will complete a randomized controlled trial evaluating the rate of SSI in adult patients who undergo a pancreatoduodenectomy following biliary stent placement when wound protectors are employed versus no wound protector use. This trial will employ block randomization. All four University of Calgary Heapato-Pancreatico-Biliary (HPB) surgeons will participate with a planned inclusion of all patients scheduled to undergo a pancreatoduodenectomy. Analysis: The investigators will use an intention to treat approach to the analysis. Categorical baseline data will be analyzed using the Fisher exact probability test. Non-categorical baseline data will be analyzed using the Student t test. SSI rates will be determined using the Fisher exact probability test. Hypothesis: Wound protectors will reduce the SSI rate in patients undergoing a pancreatoduodenectomy with preoperatively placed intrabiliary stents. Potential Impact: Given the tremendous oncologic, economic, and psychological impact of SSI following pancreatoduodenectomy, the epidemic incidence of this complication must be reduced. The additional crippling effect of refusing (Medicare) payment for any patient who receives a SSI in the United States has launched all techniques and analyses that can potentially reduce this complication into the National health care agenda. In Canada, health care utilization and economics are always a relevant and ever expanding area of importance. It is crucial that the investigators reduce complications such as SSI, regardless of individual payer sources.
Chronic Hepatitis C Virus (HCV) infection is a major cause of liver cirrhosis and hepatocellular carcinoma world-wide. Current combination therapy of pegylated interferon-alfa, ribavirin and protease inhibitors is limited by resistance and substantial side effects. The investigators identified epidermal growth factor receptor (EGFR) as host factor for HCV infection. Inhibition of kinase function of EGFR by approved inhibitor Erlotinib (TarcevaTM) broadly inhibits HCV infection of all major genotypes including viral escape variants resistant to host immune responses. Completed preclinical proof-of-concept studies in HCV cell culture and animal model systems demonstrate that inhibition of EGFR function by Erlotinib constitutes a novel antiviral approach for prevention and treatment of HCV infection (European patent application EP 08 305 604.4, Filing date: September 26, 2008; Inserm, Paris, France and Lupberger et al. Nature Medicine 2011). Since Erlotinib (TarcevaTM) is an established approved drug for cancer treatment and has a well characterized safety profile in humans, the aim of the study is to investigate the safety, efficacy and pharmacokinetics of Erlotinib, a first-in-class entry inhibitor, for treatment of HCV infection in a randomized placebo-controlled double blind clinical trial in patients chronically infected with HCV. Following completion, this trial will set the stage for a further investigation of entry inhibitors as antivirals in combination with standard of care or direct antivirals such as HCV protease inhibitors. Thus, this randomized clinical trial will be an important step in the development of novel urgently needed antiviral therapies overcoming resistance.
The purpose of this study is to see if the investigators can identify early those patients who are admitted to the hospital and have a urinary tract infection (UTI) or those patients that develop a UTI during their hospitalization.
The purpose of this study is to evaluate the safety and antiviral activity of ABT-450/ritonavir/ABT- 267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1a (HCV GT1a) infection without cirrhosis.
Although the accumulated knowledge regarding Cytomegalovirus (CMV) infection increased substantially over the past years, several issues still deserve further investigation. The epidemiology of this disease has been changing, perhaps influenced by new immunosuppressive strategies currently used and growing and widespread use of prophylaxis. The knowledge of the CMV viral load kinetics, using a polymerase chain reaction (PCR-based assay), among renal transplant recipients not receiving any prophylactic therapy will allow the determination of risk factors for and the impact of earlier intervention on CMV infection and disease. The goal is to ultimately improve the clinical outcomes for renal transplant recipients.
The purpose of this study is to evaluate the efficacy of collagen cross-linking for treatment of infectious keratitis.
The purpose of this study was to investigate the effects of three different glycemic treatment conditions (tight, conventional, and standard) in the intraoperative period on: 1) postoperative surgical site infections, and 2) postoperative procalcitonin, and C-reactive protein levels in patients undergoing open-heart surgery. Secondary aims of the study were to investigate the effects of the three glycemic treatment conditions on: 1) intraoperative blood glucose; 2) intraoperative glycemic stability; and 3) intensive care unit length of stay, in patients undergoing open-heart surgery.
This study aim to estimate maternal and neonatal outcomes after membrane sweeping in different group of patients.
The purpose of this study is to evaluate the antiviral efficacy, safety, tolerability of combination therapy with sofosbuvir (SOF) containing regimens for the treatment of chronic hepatitis C virus (HCV) infection.
