Data and Test Instruments

Stigma of Mental Illness-1: Clinical Reflections Amresh Shrivastava*, Megan Johnston**, Yves Bureau*** ABSTRACT Although the quality and effectiveness of mental health treatments and services have improved greatly over the past 50 years, therapeutic revolutions in psychiatry have not yet been able to reduce stigma. Stigma is a risk factor leading to negative mental health outcomes. It is responsible for treatment seeking delays and reduces the likelihood that a mentally ill patient will receive adequate care. It is evident that delay due to stigma can have devastating consequences. This review will discuss the causes and consequences of stigma related to mental …

Perceptual Enhancement Of Arteriovenous Malformation In Mri Angiography Displays, Abhari Kamyar, John S. H. Baxter, Roy Eagleson, Terry Peters, Sandrine De Ribaupierre

Anatomy and Cell Biology Publications

The importance of presenting medical images in an intuitive and usable manner during a procedure is essential. However, most medical visualization interfaces, particularly those designed for minimally-invasive surgery, suffer from a number of issues as a consequence of disregarding the human perceptual, cognitive, and motor system's limitations. This matter is even more prominent when human visual system is overlooked during the design cycle. One example is the visualization of the neuro-vascular structures in MR angiography (MRA) images. This study investigates perceptual performance in the usability of a display to visualize blood vessels in MRA volumes using a contour enhancement technique. …

Workplace Violence In The Healthcare Setting, Michelle M.M. Lenssen, Shirley Mccreery

Nursing Publications

Workplace Violence (WPV) is an all-encompassing term used to describe abusive behaviours directed at another with the intent to cause harm. Although the definition varies according to situations and practice settings, there is agreement that WPV has a negative impact on the health and wellbeing of nurses and the delivery of quality nursing care (Choiniere, MacDonnell, & Shamonda, 2010; Higgins & MacIntosh, 2010; Registered Nurses Association of Ontario [RNAO], 2008; Hsinag-Chu & Lee, 2011; Vessey, DeMarco, Gaffney, & Budin, 2009).

Paediatrics Publications

Our aim is to report the consequences of epinephrine toxicity leading to cardiac failure in a child and the successful management with dopamine and milrinone. A previously healthy 13-year-old girl undergoing a left tympanomastoidectomy was inadvertently administered 10 mL of 1:1000 epinephrine subcutaneously (0.175 mg/kg) on the left post auricular region in lieu of lidocaine. She developed sudden supraventricular tachycardia, hypertension and flash pulmonary edema. She was initially treated with propofol, nitrogycerin and increased peak end-expiratory pressure. Within 4 h, she remained tachycardic, but was hypotensive with an increased central venous pressure. Electrocardiogram and echocardiogram investigations showed ST changes indicative …

The Long And Short Of It: The Role Of Telomeres In Fetal Origins Of Adult Disease., Stephanie E Hallows, Timothy Regnault, Dean H Betts

Paediatrics Publications

Placental insufficiency, maternal malnutrition, and other causes of intrauterine growth restriction (IUGR) can significantly affect short-term growth and long-term health. Following IUGR, there is an increased risk for cardiovascular disease and Type 2 Diabetes. The etiology of these diseases is beginning to be elucidated, and premature aging or cellular senescence through increased oxidative stress and DNA damage to telomeric ends may be initiators of these disease processes. This paper will explore the areas where telomere and telomerase biology can have significant effects on various tissues in the body in IUGR outcomes.

Medical Physics Staffing For Radiation Oncology: A Decade Of Experience In Ontario, Canada., Jerry J. Battista Dr., Brenda G Clark, Michael S Patterson, Luc Beaulieu, Michael B Sharpe, L John Schreiner, Miller S Macpherson, Jacob Van Dyk

Oncology Publications

The January 2010 articles in The New York Times generated intense focus on patient safety in radiation treatment, with physics staffing identified frequently as a critical factor for consistent quality assurance. The purpose of this work is to review our experience with medical physics staffing, and to propose a transparent and flexible staffing algorithm for general use. Guided by documented times required per routine procedure, we have developed a robust algorithm to estimate physics staffing needs according to center-specific workload for medical physicists and associated support staff, in a manner we believe is adaptable to an evolving radiotherapy practice. We …

Health Studies Publications

The development of agricultural biotechnology humanitarian projects for food security in the last five years has been rapid in developing countries and is expected to rise sharply over the coming years. An extremely critical issue in these projects involves building trust with the community and farmers they aim to serve. For the first time, our social audit engagement with one of these initiatives, the Water Efficient Maize for Africa project, has revealed that a critical but unrecognized component of building trust with farmers involves publicly addressing the concerns surrounding stacked trait crops. As a result, we argue in this article …

Building Effective Agbiotech Partnerships Founded On Trust: A Summary Of The Challenges And Practices In Sub-Saharan Africa, Obidimma Ezezika

Health Studies Publications

The potential for improving the efficiency and success of partnerships in agricultural biotechnology is contingent on the presence of trust. As Stephen Covey (2006) asserts in his book The Speed of Trust, trust is the basis of the new global economy and is an essential element of any successful organization [1]. The presence of trust is particularly important in public-private partnerships (PPPs), in which partners with varied interests, goals, and operating principles embark on complex tasks within innovative ventures. Even more crucial is the role of trust in the success of agbiotech initiatives led by PPPs. This is cited throughout …
