Impact of Cognitive Rehearsal Training Over Time for New Registered Nurses.

Background New RNs are most at risk for being bullied in health care. Cognitive rehearsal training (CRT) as an anti-bullying intervention is a novel approach to address the issue using role-play to respond to scenarios involving bullying. Previous studies (Griffin, 2004; O'Connell et al.

Endocannabinoid system in irritable bowel syndrome and cannabis as a therapy.

Irritable bowel syndrome (IBS) global burden is underestimated despite its high prevalence. It's a gastrointestinal disease having obscure pathophysiology with multiple therapies yet unsatisfactory remedies. The Endocannabinoid system (ECS) of our body plays a key role in maintaining normal physiology of the gastrointestinal tract as well as involves abnormalities including functional diseases like IBS.

Federal public health strategies to minimize the importation of communicable diseases into Canada.

Background: The global spread of communicable diseases is a growing concern largely as a result of increased international travel. In Canada, although most public health management of communicable diseases occurs at the front line, the federal government also takes actions to prevent and mitigate their importation.

Objective: To describe the role of the Public Health Agency of Canada (PHAC) in minimizing the importation of communicable diseases through preventive measures taken before travellers leave Canada and through early detection and prompt containment measures taken when travellers arrive in the country with a potential communicable disease.

Investigation of the first cases of human-to-human infection with the new swine-origin influenza A (H1N1) virus in Canada.

The outbreak of human infection due to the novel swine-origin influenza A (H1N1) virus began in Mexico in March 2009. As of July 6, 2009, more than 94,000 laboratory-confirmed cases were reported in over 100 countries, including 7983 cases in Canada. In this report, we describe the epidemiologic and clinical characteristics of the first cluster of reported cases of human-to-human transmission of the new influenza virus in Canada.

Laboratory diagnosis of mumps in a partially immunized population: The Nova Scotia experience.

Background: In 2007, Atlantic Canada experienced a large outbreak of mumps predominately in university students who had received a single dose of measles, mumps and rubella vaccine. The present study describes the performance characteristics of reverse transcriptase polymerase chain reaction (RT-PCR) on buccal and urine specimens and immunoglobulin M (IgM) serology in this partially immune population.

Methods: Patients presenting with symptoms suspicious for mumps had a serum, urine and a buccal swab collected for diagnostic testing.

Respiratory Watch: Development of a provincial system for respiratory syncytial virus surveillance in Nova Scotia, 2005-2008.

Objective: Respiratory syncytial virus (RSV) is the most common cause of severe lower respiratory tract infection in young children and is increasingly recognized as a cause of influenza-like illness in those older than 65 years of age. A surveillance system to provide timely local information about RSV activity in Nova Scotia (NS) is described.

Methods: A case report form was developed for weekly reporting of all laboratory isolates of RSV at diagnostic laboratories around the province.

Cluster of cases of severe acute respiratory syndrome among Toronto healthcare workers after implementation of infection control precautions: a case series.

Objective: To review the severe acute respiratory syndrome (SARS) infection control practices, the types of exposure to patients with SARS, and the activities associated with treatment of such patients among healthcare workers (HCWs) who developed SARS in Toronto, Canada, after SARS-specific infection control precautions had been implemented.

Methods: A retrospective review of work logs and patient assignments, detailed review of medical records of patients with SARS, and comprehensive telephone-based interviews of HCWs who met the case definition for SARS after implementation of infection control precautions.

Results: Seventeen HCWs from 6 hospitals developed disease that met the case definition for SARS after implementation of infection control precautions.

Investigation of a nosocomial outbreak of severe acute respiratory syndrome (SARS) in Toronto, Canada.

Background: Severe acute respiratory syndrome (SARS) was introduced into Canada by a visitor to Hong Kong who returned to Toronto on Feb. 23, 2003. Transmission to a family member who was later admitted to a community hospital in Toronto led to a large nosocomial outbreak.

Computational simulation of blood flow in human systemic circulation incorporating an external force field.

A quasi-one-dimensional non-linear mathematical model for the computation of the blood flow in the human systemic circulation is constructed. The morphology and physical modelling of the whole system (arteries, capillaries and veins) are completed by different methods for the different vessel generations. A hybrid method is used to solve the problem numerically, based on the governing equation (continuity, momentum and state equations), the input boundary conditions and the predetermined initial conditions.

Theoretical model for assessing haemodynamics in arterial networks which include bypass grafts.

The paper presents a theoretical model which can be used to simulate a vascular network which includes loops and bypass grafts, a feature not possible with previous models. Using the linearised Navier-Stokes equations, the linearised equation of a uniform thick-walled viscoelastic tube, and the equation of continuity, the model is applied to a vascular network which includes a bypass graft. This method represents each segment of an artery or graft by a four-terminal-network whose A, B, C, D parameters are functions of the frequency and physical characteristics of the segment.

In vitro effect of benzimidazole drugs on the enzymes of lipid metabolism in Trichuris globulosa.

The effects of 2 benzimidazole drugs, fenbendazole and thiabendazole, on the enzymes of lipid metabolism of an intestinal nematode parasite, Trichuris globulosa, have been studied. In vitro addition of these drugs inhibited the activity of these enzymes in both male and female worms. Inhibition is competitive in the case of the lipogenic enzymes, malate dehydrogenase and glucose-6-phosphate dehydrogenase; whereas, it is noncompetitive in the case of the lipolytic enzyme, triacylglycerol lipase.

Simulation of coronary artery revascularization.

Simulation of the commonly constructed geometries of aorto-coronary bypass anastomoses was carried out using especially fabricated distensible tubes and a pulsatile pump. The system pressure was maintained between 80 and 120 mmHg. The total mean flow was set at 250 ml min-1 (Reynolds number of 200) and the pulsatile frequency was varied from 0 to 2 Hz.
