CRCHUM: at the forefront of clinical research
"Being able to ask questions and improve treatments lies at the heart of the mission of a tertiary and quaternary care hospital like the CHUM," notes Jacques Turgeon, Director of the CHUM's research centre (CRCHUM). In other words, research is an essential ingredient of health care.

Physiotherapy for the soul — treating psychosis
Psychosis is a disorder that alters our perception of reality. It is associated with various psychiatric disorders that profoundly impact our quality of life, to the point where we can no longer function normally. It is important to intervene quickly because lengthy delays before treatment result in a less favourable prognosis. But what kind of intervention? What treatments should be used? What are their conditions of success? These questions lie at the heart of Dr Amal Abdel-Baki's research.

Another aspect studied by Dr Abdel-Baki is drug and alcohol consumption before and dur-ing treatment, especially among the 55% of patients with a substance use problem. Her re-sults reveal that drug or alcohol consumption prior to treatment has fewer consequences than continued use during therapy. Patients with a substance use problem do not respond as well to treatment and have to be hospitalized more often than patients who have never consumed drugs or alcohol or who have ceased while be-ing treated. "It is clear that special intervention strategies have to be developed for these pa-

Treating advanced prostate cancer — a world first
One out every six of the roughly 25,000 Canadians with prostate cancer will not survive. each year in Canada, this disease takes 4,300 lives, and most of these patients die in considerable agony.

to ensure more effective treatments
Do you have chronic shoulder pain? If so, you are not alone. In 2000, the cost of treating this problem in the United States amounted to no less than $7 billion. This pain can be caused by several factors. Dr nathalie Bureau, a CRCHUM radiologist and clinical researcher, studies acromiohumeral disorders, a pathology that produces shoulder impingement that may lead to tendinopathy or tears of the tendons that control shoulder movements.

Of the 25,000 Canadians diagnosed with lung cancer in 2010, 20,000 will die. Since lung cancer is a deadly disease (leading cause of cancer-related deaths) and difficult to accurately diagnose and to treat, Dr Moishe Liberman, a researcher and thoracic surgeon, decided to compare two techniques for evaluating the stage of the cancer's development.

Stemming HIV transmission in an at-risk population
The many dangers related to injection drug use, especially among individuals who share needles with other users, are well known. This practice opens the door to the transmission of serious diseases, in particular HIV, and has consequences for the public in general. However, a new study led by Dr Julie Bruneau, a CRCHUM physician and researcher, has revealed that transmission rates have declined among injection drug users (IDU) in Montreal.

Innovations in liver cancer treatments
Liver resection is the only curative approach for hepatic metastases of colorectal origin, with a survival rate of 50% after five years. This operation involves removing the region of the liver that contains tumours and then allowing what remains of the liver to regenerate itself over time. But just which portion of the liver needs be removed, and can we intervene at an earlier stage of the disease to limit the extent of the intervention? The CRCHUM's Dr Réal Lapointe and Dr Franck Vandenbroucke-Menu devote their clinical research activities to finding answers to these questions.
tion. Lapointe and Vandenbroucke-Menu con-ducted a study in collaboration with the IRCAD (Institut de Recherche contre les Cancers de l'Appareil Digestif) in France to validate a new 3D imaging technology that evaluates the total volume of the tumours and the remaining liver. The idea was to simulate the liver resection using a 3D reconstruction of the patient's liver, tumours and blood vessels and to determine
the volume of the remaining liver. This study was the first of its kind to compare this technology to the

Detecting and treating prediabetes
Systematic screening for prediabetes is not performed in Canada even though several studies have shown that treatment with or without medication can decrease the risk of developing diabetes. Since January 2009, Dr Jean-Louis Chiasson, an endocrinologist and researcher at the CRCHUM, has been working on this issue with his european colleagues within the framework of an important clinical research project in China.
By Dalila Benhaberou-Brun
WhAt is prediAbetes?
Prediabetes is a condition in which a person displays a high fasting blood sugar level (6.1 to 6.9 mmol/L) or a blood sugar level between 7.8 and 11 mmol/L two hours after an oral glucose tolerance test (75 g of glucose). Dr Chiasson is concerned because this condition carries an in-creased risk not only of progressing to diabetes, but also of causing cardiovascular problems. In his view, patients need to be treated at this stage. To this end, he is participating in the ACe study, a major new clinical research project.
Ace, A good cArd?
Funded by Bayer Laboratories, the ACe study is an original research project including 7,500 pa-tients with prediabetes who have experienced a cardiovascular event. The study's objective is to assess the efficacy of the drug acarbose in pre-venting the incidence of mortality, myocardial infarction and cerebrovascular accidents as well as the development of type 2 diabetes in predia-betes patients.
An earlier international study directed by Dr Chiasson demonstrated that acarbose reduced the risk of developing diabetes by 36% by re-

Improved monitoring of women with cervical pre-cancer
Women with severe precancerous changes of the cervix — the stage preceding cancer — are treated by surgery. They are then monitored for two years with colposcopy, a medical procedure that involves a visual examination of the cervix with a special magnifying device. Unfortunately, the treatment fails in around 15% of cases and the pre-cancer could go unseen since colposcopy, the main method used in Canada, does not detect certain precancerous lesions that persist after surgery.
